Base Kit Components 110H

These components are subject to change based upon your selections.

Options:

4" Block - The standard system comes with a 4" block.

Rear Block and Add A Leaf - Add $74.72

If your factory leaf packs are worn out or you plan on doing some towing, the add-a-leaf option might be a good choice for you. The add-a-leaf in addition to the block will help freshen up you old worn out factory leaf springs.

52" Rear Leaf Spring - Add $497.13 

56" Rear Leaf Spring - Add $513.97

Replace those old worn out leaf springs with new BDS Glide-Ride springs. This upgrade will eliminate the need for a rear block thus reducing axle wrap and improve towing characteristics. Measure your truck to determine the length required.

BDS Glide-Ride leaf springs will reduce axle wrap and create a more controlled and stable feel when towing. These springs are covered by the BDS No Fine Print Warranty. Actual leaf spring may not be exactly as shown in photo.

Bushings are not included when ordering these leaf springs separately. Order one bushing kit per spring.
