Description

The Deaver spring is a complete replacement of the OEM spring and is arched for 4 inch over stock rear lift height while maintaining excellent ride quality via being made from high-quality spring steel, a higher leaf count with thinner leaf material for a more compliant ride.A military wrap is used on the front eyelet for safety, the ends of each leaf are diamond-shaped cut and have anti-friction inserts for smooth movement, and the pack is secured with included center pin and retaining clips. Using leaf springs over lift blocks helps reduce wheel hop or axle wrap. Made in the USA.
