I thought that was designed for a car? IT's got to be junk, coming from AutoZone. Seriously, though, an aftermarket offroad shock would work better, last longer and only cost a bit more. Rancho, Pro Comp, Superlift all have some in the $30-$40 price range. If you're cheap like me, get the Superlift Scratch&Dent shocks off ebay for $9. Same thing as there $35 shock, just has some blemishes. JSM84
