Product Overview
The Cognito Deaver Mini Leaf Pack Set is designed for Silverado and Sierra owners who want improved rear ride quality with the added benefit of adjustable rear lift height. By replacing the harsh factory bottom overload spring with a progressive mini leaf pack, this set helps reduce the stiff, jarring feel often associated with factory overload spring setups.
Built for compatible Chevy Silverado and GMC Sierra 1500, 2500, and 3500 applications, this mini leaf pack set is ideal for truck owners upgrading ride comfort, leveling rear stance, or fine-tuning suspension height after other suspension modifications. Cognito lists the 1500 application for 2019–2025 Silverado/Sierra 1500 2WD/4WD and the HD application for 2011–2025 Silverado/Sierra 2500/3500 2WD/4WD.
The design uses a progressive overload spring rate to help deliver better ride quality while still adding rear height. On 1500 applications, Cognito notes the kit can provide 1–3 inches of rear lift if one or both spacer blocks are removed. On 2500/3500 applications, Cognito notes the kit can provide 1–2.5 inches of rear lift depending on spacer block configuration.
Additional features include included center pins, set-based packaging, and a 2-hour DIY install time listed by Cognito. These mini packs are designed only for use with stock spring packs and are not intended as a universal replacement for aftermarket leaf spring packs.
Engineered with vehicle-specific fitment, the Cognito Deaver Mini Leaf Pack Set offers a clean suspension upgrade that improves rear ride feel while allowing customers to dial in added rear height.
Installation is typically a direct spring-pack modification that removes the factory bottom overload spring and installs the Deaver mini pack to the stock spring pack using included center pins. Cognito lists a 2-hour DIY install time for both applications.
Whether you're upgrading for improved ride comfort, added rear stance, or a better-balanced suspension setup, the Cognito Deaver Mini Leaf Pack Set delivers progressive spring performance, adjustable rear lift, and proven Cognito suspension quality. Now Available at LEER!
