MaxTrac 401900 Rear Shock Extenders Fits 2019–26 Silverado 1500

A Simple Solution for Lowered Silverado and Sierra Trucks

When lowering your 2019–2026 Chevrolet Silverado 1500 or GMC Sierra 1500, proper shock positioning is critical for ride quality and suspension performance. The MaxTrac 401900 Rear Shock Extenders are designed to relocate the factory shock mounting points, allowing your original shocks to operate correctly on trucks with a 4"–6" rear drop.

Built from heavy-duty steel and finished in a durable grey powdercoat, these shock extenders offer an easy bolt-on installation while helping preserve suspension travel and overall ride comfort. Best of all, they work with factory Adaptive Ride Control shocks, making them an excellent choice for modern GM truck lowering projects.
