Adds Compliant Ride Quality While Improving Utility and Stance

2011-2025 GM Sierra/Silverado 2500/3500 owners who are looking to replace sagging suspension, gain additional ground clearance off-road, or just want a more aggressive stance will find a solution in Cognito's 4" Deaver Leaf Spring Pack. The 4" Deaver Leaf Spring Pack provides an effective solution. Cognito's 4" Deaver Leaf Spring pack reduces rear-end bounce and axle wrap compared to using lift blocks. By utilizing a higher leaf count combined with thinner leaf material, the Deaver Leaf Springs offer a smooth ride quality for both on and off the road. The additional lift gained from the springs can also improve rear suspension sagging while towing. The springs feature military-wrapped eyelets which provides an extra layer of strength and reducing stress during extreme articulation, further enhancing your truck's capability.

American Made Steel with Diamond-Ends and Military Wrapped Front Eyelets

Deaver leaf springs are well known for their high-quality USA construction, and their 4" Leaf Spring Pack is no exception. The Deaver springs are made of high-quality steel with diamond shaped cut ends and anti-friction pads between the leafs to ensure smooth spring operation. Military wraps that form a double wrap are used for the front eyelets, enhancing strength and safety. The leaf pack is secured by the included center pins and retaining clips which assist in holding leaf springs together during abuse.
