I was wondering what the lifespan of the autoride shocks is. I know how to tell on the rear "air-ride - leveling" shocks, but on the fronts? My Yuk is a 2500 so I actually have electronic shocks all the way around with no air. Traditional style shocks get bouncy, but I have heard the autoride shocks get stiffer. I dont know. Mine are definately not bouncy, but the truck has 165k miles. Anybody know?
