The GMC Sierra 2500 HD Leaf Spring Pack - Rear - ICON - SWR - '11-'26 is a direct-replacement rear pack for 2011–2026 Sierra 2500 HD trucks. It refines ride comfort while retaining factory rear ride height.

Built as a complete OEM-replacement, this ICON pack reduces rear spring rate by about 20% for a smoother, more controlled ride when you’re not frequently hauling or towing. Its higher overload transition helps the truck absorb small bumps, and it works with ICON Vehicle Dynamics shocks, stock dampers, and other aftermarket options to suit your setup. Ride height remains stock, so stance and geometry stay consistent with factory specs.

Features

• Direct OEM replacement, complete pack.
• Retains 0" rear lift (stock height).

• Improved comfort versus OEM leafs.
• Optimized overload for small-bump control.
