The Cognito Deaver Mini Leaf Pack Set fits the 2019-2025 GMC Sierra 1500 and replaces the harsh factory overload spring with a progressive-rate mini pack.

Improves ride quality while adding up to 3in of rear lift when the factory spacer blocks are removed.

Install Difficulty: Professional Install Only
Requires disassembly of the factory leaf spring pack to install new center pins; typically takes 2-3 hours per side with a vehicle lift. Professional alignment recommended after any suspension modification.

Product Overview

This progressive overload leaf pack bolts to the factory spring pack using included center pins. It softens the abrupt engagement of the stock bottom overload for a smoother loaded and unloaded ride.

Removing one or both factory spacer blocks yields 1-3in of rear lift, letting you dial in ride height without a separate lift kit.

Compatible only with stock Sierra 1500 spring packs.
