Eliminate your block and factory rear spring with these Progressive Rate Springs from Deaver and enhance your ride and eliminate axle wrap! Deaver's Progressive Series Springs are high quality 9-leaf and 10-leaf units fabricated with high grade 5160 "AMERICAN MADE" steel. A higher leaf count spring allows the use of thinner leaf material that yields a more flexible, progressive leaf stack, producing a much smoother spring rate curve throughout the complete suspension cycle. The even, linear compression rate curve of the Progressive System Spring is the primary key to superior ride quality.

Other design features include diamond cut inner leaf ends minimizing shear points, anti-friction pads inserted between the leafs for a smoother ride and quiet operation, full military-wrapped spring eyes for superior durability, and OEM bushings. Combined with properly valved high performance shock absorbers, the ride is enhanced beyond belief!

Kit includes bushings. If you would like to add u-bolts, please select this option.
