The PO of my son's truck was an idiot, he ran a chevy 1 ton AAL on the rear suspension, causing a 3" higher lift in the rear, that rode like s***. So I ordered a 1.5" AAL from Wheeler's and put it in today, I also removed the overload leave since he never hauls anything or tows. Anyways, it was a great product at a decent price, wanted to give them some props.....
