I wanted to replace my stock bumper on my Jeep, have a winch installed, and get on onboard compressor. I had some really specific needs and wasnt sure Id be able to get what I needed. (I cant remember the name of the guy that helped me on my first visit), but I was so impressed. He spent probably 40 minutes going over everything. We liked through various websites to find exactly what I wanted. I was unable to get the compressor, but thats not RSs fault. Blame Covid😊. Besides that I also asked him some questions about the diesel engine because Ive never had one before. He answered all my questions and never once made me feel like I was asking dumb questions. When I brought my Jeep in for service, I dropped it off with no wait. I think it was finished around 4pm the same day. John and I talked through some additional work Id like have done. Ill definitely be back.

Gotta say they did a fantastic job on the 4Runner. Rides great all things considered. John was informative, understanding, and up-front. I will be coming back for future work without a doubt. They offer a free check up to garuntee the quality after 500ish miles. That shows they care about the work done to your vehicle.One thing I will say, make sure the exact parts you want are available. The wheels Rock Solid received from the warehouse did not fit at all. NOT ROCK SOLIDS FAULT, but if I drop a $3000 dollar deposit prior to any work, the parts should be in the garage and checked before I drop my vehicle off.John did say that if the parts came in incorrectly, I would have to wait a little while longer, but my truck was lifted before they realized the wheels wouldnt fit. Again, not their fault at all and I would be happy to continue business with them.

Rock solid 4x4 did a awesome job helping me get my truck fixed up after in was stolen and damaged. Was very upfront and fair with everything and understood it was a bad time to put out a lot of money as I’m the only one working because the virus. Will definitely be going back in the future. No one else will touch my truck. Thanks to John and the crew. Definitely recommend this shop for anything truck related.

John, Matt and Travis are all knowledgeable, highly skilled and honest. You can trust these guys to customize your truck or Jeep.

John was great at explaining everything to my son. Went to 3 different places with worse ratings only to find out this is the place to have any work done. We will be back.

They have done some great work on mine and my familys trucks.

John and Travis are fantastic when if comes to knowledge, workmanship, and customer service. My 37s fit great, my 30 light bar is installed very well, and my alignment is spot on. I highly recommend these guys and this shop.

I had Rock Solid 4x4 do a 3 1/2 inch lift on my 2014 Wrangler. Great job guys! All work was done on time, and within their bid. They even schedule a check up after a few hundred miles just to make sure all is OK. In my case my steering was a little off after some 4wd low off roading. Evert thing was fixed after the checkup. Great job! Support your local small business!

From the first email I received from John I knew I was going to the right place. He agreed to meet with me and go over my Jeep build same day. I expected to meet with him for a few minutes and get a price. I was wrong John met with my wife and I for about an hour and half. He went over every detail and showed price points for different products and labor costs. After meeting with John I decided he and Rock Solid 4x4 are the only people I ever want to work on my Jeep. I cannot wait to see how this build turns out and will update with photos once completed. I did my Jeep back and it is amazing. Rock solid 4x4 did an amazing job. Looking forward to coming back and making more modifications.

Transparent with options, pricing, and availability. Quality is equally as important to him and his team as it was to me. I personally had friendly interactions with John himself, and his technician working on my truck. Great experience. Great place of business. No one was able to compete with pricing! (Leveling kit)

Made a appointment 2 weeks in advance for a easy fix. Never even moved the car or looked or even called me back!! Kept my keys overnight with no call. Much better shops around the area

I knew after I read the reviews that I was going to the right place. I was dealing with very bad death wobble and drive train noise with my 2015 JK and John got it figured out and handled faster and more cost effective than I could have ever imagined. I will never use another shop again. Rock Solid 4x4 is on a whole other level of knowledge, honesty, and customer service. Thanks again guys!

Brought in a Chevy Express to be lifted, and they were extremely helpful with choosing the best option for me. Very nice people and well priced. You really can’t go wrong here.

Requested an Quote online for some Rock Skins and some Rock Slide Engineering Power Steps. A guy called he gave me some numbers but items I wanted were missing or substituted. I told him on the phone that I wanted lights for the steps which were not included and additional rock guards for the steps. He also quoted me Rock Slide Engineering Skins that I did not want since they are UGLY. At the time I was interested in the DV8 rock Skins. He said hed call back with a final quote when he had time and I never heard back. If you say your going to do something you should follow up. I guess they didnt need my business. They may do fine work but Ill never know.

Got a 2 lift on my Tacoma and John was very transparent of the entire process and bent over backwards getting parts during the pandemic to make everything work. Highly recommend for anyone looking to get work done on their vehicle.

Did great work, and pricing was fair. Ill definitely be bringing my Jeep back for work in the future. Highly recommend them!

Put a new heavy duty bumper and winch on my truckGreat work at a great fair price and no BS...You wont go wrong picking these guys to do your work.

Friendly staff, very good with alignments. I drive over an hour to get here because this shop is that good.

Great bunch of guys. Fair prices, and they know their stuff. I have a lifted FJ Cruiser and they get the wheel alignment spot on.

I had purchased a Lexus GX 460 and wanted to do a very modest lift to help with fitting some larger tires. I had great concerns about retaining my ride quality. John at Rock Solid made sure that all of my concerns were addressed. He helped to guide me in the right direction of what to consider with my lift; He listened to me ramble on the phone many times throughout the process and was always patient and responsive to my calls/texts. It was clear that he and his crew have a wealth of knowledge and experience, and he was able to explain things on an advanced level when considering retaining my factory ride. I would recommend anyone looking for off-road or suspension related items to check them out!

I spoke to John on the phone, I was having difficulty getting my doors off my Jeep. He told me to stop by and they would take a look and see how difficult it might be (saying if I would need to make an appointment if it was going to take a little time to get them off) but reassured me that he could definitely help me. He was incredibly kind and I immediately wanted to stop by. I stopped by a couple days later and was helped by Travis and another gentleman. They both stopped what they were doing and immediately got to work on trying to get my doors off. Ended up having to get another gentleman for one of them but they got them off! They didnt charge me anything! I will 100% be back here when I get work done! Without a doubt! I will also tell everyone about them! THEY ALSO PRICE MATCH!

The guys at Rock Solid know what they are doing. I upgraded my Tacoma to 35 tires and was having rubbing issues. They took care of it and no more rub. Highly recommended for your Toyota or 4x4 needs. Check them out. Did not disappoint.

Rock Solid 4x4 does fantastic work. John and his team are highly transparent about cost, timing, and expectations. Their work is very high quality and reliable. John and his team can handle everything from routine/standard maintenance to custom fabrication work. They custom fabricated a roof mount/support system for our roof top tent with a full light system. I recommend Rock Solid for anyone looking to improve their off road rig!

John took care of all my concerns. They did a great job installing the Rough Country 3.25 inch leveling/lift kit on my 2015 Chevy Colorado. He was upfront and honest. Thank you!

These guys are the real deal. I developed the dreaded Wrangler death wobble. John takes you back in the shop and gets hands on with your Jeep and shows you what the issues are. No surprises, no lies, no b.s. No pressure to perform work that is not needed. My estimate was around half of what the dealer and a few other 4x4 shops had quoted. As long as I have my Jeep, Ill never go anyplace else.

Was not able to do business with this shop even after three attempts to contact them about the wheel and tire package. Just go to discount tire, they price match.

I had a 2010 Mitsubishi Outlander that had some issues with the hitch that we installed. John listened to my concerns and gave me an honest answer. I generally dread going to mechanics and shops for help but for once I was treated respectfully. Everyone here was friendly and helpful. While most of my friends are amateur mechanics and DIYers, Ill recommend this place to anybody that needs any 4x4 specialists.Thank you so much guys! I really appreciate it!

These guys rock. Just got a 2.5 inch level on my Ram. Super timely, transparent, and professional. I’ll be coming back here for more upgrades. Can’t say enough about these dudes.

Got a Ox locker and 4:88 gears installed. After calling all the 4x4 shops around town John was the only one that took time to talk to me about it and give me a quote. They did a fantastic job on the install and at a fair price.

Since the day I started taking my Jeep to John at Rock Solid 4x4, I knew this guy was genuine. He does absolutely amazing work, and is the most honest and reliable person I have ever dealt with in any industry. Most shops will milk you for every penny they can get out of you. Rock Solid 4x4’s main focus is to get you back on the road as efficiently and cost effectively as possible with 100% client satisfaction. I will only take my vehicles to them! Highly recommended for any make or model!

I reached out to John about installing a 2 inch spacer or lift kit on my 2019 Jeep Cherokee. Unfortunately, a quality lift product does not exist yet for this vehicle. He was very upfront about the results he has seen so far with the existing products and recommended I wait until a more reliable kit comes to market to move forward (when he could have easily installed the subpar product that the other companies I spoke to recommended). John truly strives to provide top quality services and clearly values honesty. I will only be using Rock Solid in the future.

10/10 these are the guys for your 4x4 needs. True chads

Very knowledgeable., professional and super helpful. I took my Jeep in for one problem, they figured out it was not what I had taken it to them for and fixed it the right way! I will definitely be going back for all my Jeep mechanical needs.

Awesome customer service, guys know what they are doing! Never tries to hustle you into fixing unnecessary stuff.

Good service, fair price. I wish dealing with more shops was like my experience here. Ive only used Rock Solid for two small items, but both were completed on time with very good service.

Great bunch of guys! Got me a great deal on a Rough Country lift kit for my 77 Chevy K10. It had an original suspension that was entirely shot. They replaced it in a day and now it runs smoothly. Love the work!

John and Rock Solid is hands down the best mechanic shop Denver has to offer. John and his crew do the most incredible job on any and every car they work on. John will not settle until the job is done 100% to his specifications. If there is one company you can trust with your vehicles it’s Rock Solid. Thanks for all the great work.

I cant say enough good things about Rock Solid 4x4 and the owner, John. I needed new shocks on my 2006 4Runner and I took it to another place first and they wanted to charge me a fortune, and didnt really seem to know what they were talking about. John charged me less than half what the other place did, and he really knows his stuff. Im so glad I discovered Rock Solid! John will do whatever it takes to make you happy, and explains everything in detail so you know whats going on and there are no surprises. I will definitely be back.

Great customer service, quality work and upfront estimate, very easy shop to work with,I will back in the future for sure!

Hi everyone,. I just had my 2010 Nissan lifted 6 inches with some nice rims and 32 inch tires on my truck. Rock solid did a awesome job and truck looks sweet. The pricing was pretty good. I highly recomend this place any day of the week. Thanks John

I have many places much closer to me to have my vehicles serviced. Rock Solid has been a God send to me and my family. The words knowledge ,integrity, and honesty comes to mind when I think about the quote and service they provide. I would give them 6 stars if Google allowed me to due to the folks there exceeding my expectations.

I brought my 2004 Tahoe into John and his shop for work on my power steering gear box, steering components and some various leaking hoses. The work was explained in detail to me and completed in a timely manner. The pricing was extremely fair and competitive. Will definitely be visiting this business again for future work on my vehicles.

I own a 08 Tundra lifted 16 on 40s. It needed alot of work done to make it street worthy. The first guy who i trusted to fix this truck screwed me over bad. I didnt know who to go to and to trust to finish this project. Then i ran into John. He has been committed and has put a lot of effort into finishing this project. I would never thought i would find the right guy because this is not a truck you would consider a daily driver. Its been my dream to own this truck. John told me if i can dream it, that he can build it. I am very pleased with what he has done so far with my dream. He is very knowledgeable. Any time i have a question or dont know something about my Tundra with the suspension or what not he will sit down with you and explain in full detail. He is not out to take your money. He will actually try to save your dollar. He will do the least expensive. If you need something more he will tell you first before doing anything that would break the bank. John is the go to man. He is a man of God and is very honest.

I came in with a pitman arm with the shaft from the gear box stuck in it along with the steering gear box with an extender on it. They where able to knock the broken shaft out of the gear box and removed the extender with a stripped head saving it so it was still reusable. They were quick and did a very good job. I will be back with my trucks to them for future work.

Might be the best group of professional mechanics Ive ever worked with. I bought a used Wrangler with 200,000 miles on it and almost everything under the floorboards was shot. These guys got everything fixed/ replaced for a fraction of the cost that other people were quoting me for, and they helped me out with some other stuff too. Cant thank you guys enough.

Im extremely impressed with their customer service and honesty. Never tried to upsell or convince me of any particular route just listened and then offered advice and options. Great shop!

The basics for a 5-star automotive review IMO is to be honest, fair pricing and do the work right. I just got a 99 F350 that needed a bunch of little things with a potentially expensive exhaust manifold/pipe repair. They could have told me it was a painful repair and charged me for a lot of work and Id have been hard pressed to argue ,instead they indicated it went better than expected and billed me an hours labor and some parts. An honest automotive shop will always be busy and make good long term revenue from customers who can trust them - and so far John and his team appear to understand that.

First thing first, John! You the man! Honest, quality service. Fair. I mean I can go on. I was sceptical at first because it seemed to be a shop for more OFFROAD vehicles and I have a lowered truck, but John and his team were able to help me out. Great, honest people. It seems they offer other services as well not just suspension and John and his team will be the first I call to see if they can do it.

Rock Solid also describes their customer service and professionalism. After another shop did some poor work on my jeep leaving me feeling anything but confident, John and crew went through it and fixed or replaced several things and now I finally am confident that my jeep is ready to do some serious crawling again. Fair prices and no up selling or trying to do unnecessary work but will make sure you leave with a vehicle that is safe! Rack solid 4x4 is now my got to shop and I will be back for any future needs.

John spent so much time teaching my 16 year old son about his new Jeep; how to take care of it, what he do in the future, etc. Very reasonably priced!!!!! Honest, but not pushy!! Very knowledgeable!!I highly recommend Rock Solid!!

John is the best, simple as that. He will educate on the process and ensure you are in the loop with the entire job. John has built two trucks for me, Im getting ready to send another one his way. If you want the job done right the first time John and his team is the right choice.

This shop and guys at Rock Solid 4x4 are amazing! John listened to what I was looking for and delivered a outstanding service. I highly recommend this shop.

Outstanding service true to their word. I have been a long time customer of Johns for many years and he never disappoints. I have referred many of my friends to him.

I was having issues with my steering on my Ram 3500. The truck was all over the road. I self-diagnosed the problem as being the steering box. So, I purchased a Red Head steering box ($500) and contacted John to have him install it. Before installing it, John went through the truck and determined that the drag link and tie rod ends were shot and likely causing my issue. Unlike a lot of mechanics that would have just installed the steering box, John went the extra mile and really evaluated the vehicle. He also educated me on the absolute art of aligning these trucks. So, after installing new steering linkage, steering box brace and dual steering stabilizer, my truck is very tight and I could not be happier. I cannot say enough about this shop and the confidence I have in them. John is the man.

John at Rock Solid lifted my 2012 Xterra and performed the alignment. Should have been a simple job, but as is often the case, the Nissans Cam Bolts were rusted solid. He had to replace the the lower control arms to set the camber, but when finished, the rig drives like a dream. These guys do great work and you can take them at their word. Nothing but good things to say. Ill use them from now on!

This is my second time having work done by John and his crew at rock solid.Absolutely happy with everything they do .All my work goes to them thanks guys your the best.

Best in town!

Great team at Rock Solid, customer service is paramount! Very knowledgeable, trustworthy and honist! Quick turn around and great rates. Johns shop is the only place ill go. A+++!

Went above and beyond in service and professionalism. Im so happy they fixed my problem for a very reasonable price

Great shop, great staff, very happy with my experience. Wouldnt hesitate to send anyone their way.

John was more than informative and actually took the time to educate me before and during the alignment process! He and his team also were able to correct more than what the dealer or Les Schwab failed to do. Will definitely be returning to Rock Solid although I live far away, lol. Great work!

John and his team are awesome to work with. Their customer service is top notch! I will be back for more upgrades.

John and Rock Solid 4X4 are the best of the best. They are very attentive to detail and always provide the best service and high quality products. No need to look any further for your 4x4 powertrain needs.

One of the best Mechanics I ever found highly recommended Very knowledgeable These are the guys to go see

John and his team were exceptional to work with. Highly recommended.

This shop and staff are legit. High quality of work and good communication with no BS.

John and his team do exceptional work! He has been working on my 1985 Cj7 for a number of years now. He and his team have done everything from re-gears, axel seals, top end motor work, suspension, wheel and tire upgrades, wiring, custom fabrication of mounts and steering and the list just goes on and on.My Jeep is a rare bird as it is one of the few registered CJ7s with a 400+ hp AMC V-8 under the hood. John and his team have always treated her with a level of respect I think she deserves and have helped me immensely to work through many many different issues that have presented themselves while working with such a unique powerplant under the hood.I can say whole heartedly that John and his team have not only been a trusted source when needing repairs and modifications, they have also become friends! Friends that I trust with not only my jeep but quite literally my life and my families life. John always strives to make sure the job is done right and safely the first time. He never just slaps something together just for the paycheck, he works with you to make sure that you know the intricacies of what is going on when swapping or modifying crucial components. If something doesnt look right to his eye, he stops and calls for verification of what you would like done and how best YOU would like to proceed. To me this is invaluable!Needless to say, the next time I need my jeep modified or fixed or altered in any way, its going straight to Rock Solid 4x4!

Good mechanics great service. Very friendly

My go to place for alignment. Thank you.

John takes the time to go through your vehicle and weigh out all your options.

Cool as people!
