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.

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 !!

Great Lowering Solution

Needed to move my axle two inches forward to center the rear wheels in the wells. I used Speedway's 3 inch lowering blocks to achieve the proper stance on my 50 Fleet Line. I was happy to save money by purchasing only the aluminum blocks as my u-bolts were already long enough to accommodate the blocks. Otherwise you'll need to consider buying the kit with long u-bolts.
