Great work, great price, great timing, and AWESOME customer service!In January, I needed to have the driveshaft rebuilt for my truck. I am a home handyman, and not a professional mechanic or from any other business that buys a lot of their products, but Certified Power treated me as if I were their most valued customer. There is no such thing as a small-fry for these guys. They were friendly and helpful from the beginning to the end. The work was done quickly, the price was very good, and the quality is great. If I could give them a rating that is better than Excellent, I would. If I ever need driveshaft work or hydraulics again, I will not hesitate to return to Certified Power, and I will definitely recommend them to my friends.
