Cognito 11-25 Chevy/GMC Silverado/Sierra 2500/3500 HD 2WD/4WD Deaver Mini Leaf Pack Set

The stock bottom overload spring on your 2011-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500/3500 HD can feel pretty harsh. This Cognito Deaver Mini Leaf Pack Set is designed to replace that stock spring with a progressive overload spring. This means you get a much smoother ride, especially over bumps, while also gaining adjustable rear lift. By removing one or both of the included spacer blocks, you can achieve between 1 and 3 inches of lift, giving you the option to dial in your truck's stance.

These mini packs are built to work with your truck's existing spring packs, attaching directly to them with the new center pins that are included. This design makes for a straightforward installation, often completed in about two hours. The progressive spring rate is the key here; it allows the suspension to absorb smaller impacts more comfortably than the stiff stock overload, while still providing the necessary support for heavier loads or towing. It’s a smart way to improve both ride quality and capability without a complete spring replacement.

This set is sold as a complete kit, ready to install on your 2WD or 4WD truck. It's a well-built solution made in the USA, designed to integrate seamlessly with your factory suspension components for a noticeable improvement in how your heavy-duty truck handles daily driving and hauling.
