I now have about 5,000 miles on this kit and have gained 4-6 MPG increase, no exaggeration. Tip: Use the trucks power steering as a press to remove the stock hub assembly from the steering knuckle. I am not a professional mechanic and I completed the work by myself, the install instructions are very good. This kit drives like a dream, the front end feels lighter while steering. I installed this kit with the Dynatrac Hub upgrade, kit# DNCR60-3X1104-E, on my Manual trans 20 5.9 diesel with 115,000 miles on it and am extremely pleased with this product. Stop shopping and pondering, it works! +MPG+ and not wearing out front end components.
