Cognito 11-24 Chevy/GMC Silverado/Sierra 2500/3500 HD 2WD/4WD Deaver 4 Inch Leaf Spring Pack K97

If you're looking to lift the rear of your 2011-2025 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD, these Deaver leaf spring packs from Cognito are a solid option. They replace your factory springs and are specifically arched to provide a 4-inch lift over stock, helping to reduce rear-end sag and improve the stance of your truck.

These aren't just any springs; Deaver uses high-quality spring steel and a higher leaf count with thinner material. This construction is key to achieving excellent ride quality, making the ride more compliant and comfortable compared to stiffer, less flexible springs. For safety, the front eyelet features a military wrap, and each leaf end is diamond-shaped and includes anti-friction inserts. These details help ensure smooth movement and prevent binding. The pack is secured with the included center pin and retaining clips, making it a bolt-in installation that requires no cutting or welding. Using a full leaf spring pack like this also helps reduce common issues like wheel hop and axle wrap, especially when carrying loads or under acceleration.

This set includes two leaf spring packs, enough for the rear of your truck. They are proudly made in the USA and are designed for both 2WD and 4WD applications. When installing, remember to refer to the manufacturer's instructions for proper fitment and any specific torque requirements.
