I'd just like to share that the shock portion of the reman Arnott "AutoRide" shocks are NOT rebuilt. Only the air bag/bladder portion. That means that if the reman that you buy from them came off a vehicle with 300K, the shock is a 300K mile shock. The air bag is fresh, but that's it.
I found all of this out when one of the rear "AutoRide" shocks on my Denali started leaking. In my research I found that Monroe was actually the OEM for these and just ordered brand new units through Rock Auto for about $40 more, each. That way I was able to keep the nice ride and Stabilitrak functions.
