LB4LK | 4 Inch Aluminum Rear Block and U Bolt Kit

The hot set up for the rear of small and mid-size pick ups plus suv’s where the axle is on top of the leaf spring is the good old lowering block kits. Available in both aluminum and steel, there is a block kit to fit your needs! All kits have new U-bolts, nuts and washers!

In 97 Chevy changed the shape of the rear leaf springs in such a way to require a steel plate to seat the lowering blocks on. This keeps the blocks from getting point loaded and potentially breaking. Use instead of LB1023-4! for 1997 – 2003 S-10’s and Blazers

We recommend Calmax SuperShocks, check in the kits for the best part number for you!
