Cognito Deaver Mini Leaf Pack Set for 2011-2025 Chevy/GMC Silverado/Sierra 2500/3500 HD (210-91230)

Fits 2011-2025 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD 2WD/4WD trucks.

The Cognito Deaver Mini Leaf Pack Set is engineered to improve the ride quality of heavy-duty GM trucks by addressing the harshness of the factory suspension. This progressive mini pack replaces the thick, stiff OEM bottom overload spring with a progressive-rate leaf assembly that offers a more compliant feel on the road. When one or both factory spacer blocks are removed, this set provides an adjustable 1 to 2.5 inches of rear lift, though total height adjustments can range from 1 to 3 inches depending on configuration.

These mini packs are designed exclusively for compatibility with stock spring packs and include new high-strength center pins for a secure installation. Manufactured in the USA, this kit is a functional upgrade for owners looking to balance increased ride height with a smoother suspension response.
