My 1500HD failed inspection due to bipod and track arm wear. The store charged $450 for a replacement. I ended up going to Revain and bought the crank, cocking arm and cocking arm mount for a lot less. The swap took about 3 hours including removing the steering box as I couldn't remove the tie rod. I also installed a cognito kit to beef up all the steering. Wow, what's the difference, now the truck doesn't wander across the street anymore. I thought it was because of the crappy rubber I put on. It turns out that the new levers make a big difference. These Moog parts appear to be much stronger than the stock parts and cheaper when bought from Revain.
