Lowering blocks

Great problem solver !! if you have clearance issues with your suspension or you just want to get your car lower to the road , this is the thing to use !! if you are gonna paint them , bead blast the edges first to allow the paint for something to stick too !!

Just what I needed to correct a crooked frame.

I own a used pickup. Previous owner must have backed into something and bent the frame at the kickover. Driver side sits 1/2 lower than passenger. This lowering block was just what I needed to raise my spring pack that little distance and even up the bed.
