GMC Sierra 2500 Leaf Springs - Rear - Cognito - Deaver Mini Leaf Pack - 11-25. A progressive mini overload that replaces the harsh stock bottom leaf and adds adjustable rear lift with improved ride quality.

Built by Deaver for Cognito, this mini pack is designed for stock spring packs on 2011-2025 Chevy/GMC Silverado/Sierra 2500/3500 HD 2WD/4WD. It installs in place of the thick overload and fastens to the OE pack with new center pins included. The progressive rate smooths small bumps while maintaining control under varying load. Depending on spacer block use, expect about 1-3 inches of rear height change, commonly 1-2.5 inches when one or both spacer blocks are removed. DIY friendly at roughly 2 hours, made in the USA, and sold as a set.
