About this kit

4-Inch 4-Degree Spacer Air Spring Kit with Compressor, GM HD, fitment-checked

Rough Country 100347WC is the fully loaded GM heavy-duty air spring package: rear air spring kit, a 4-inch, 4-degree spacer set, and a wireless air bag controller with onboard compressor. Coverage runs 2020 through 2026 across Silverado 2500 HD and 3500 HD and Sierra 2500 HD and 3500 HD in 4WD and RWD. Rear sway bar and frame-side-mounted 5th wheel hitch trucks are excluded.

Three assemblies ship under this part number, and the 4-inch, 4-degree spacer set is what differentiates it from the other GM heavy-duty air spring kits in the line. Applications cover 2020 to 2026 Silverado and Sierra 2500 HD and 3500 HD, work trims through Denali Ultimate, in both drive types. The onboard compressor and wireless remote handle pressure from the cab. Before ordering, rule out a rear sway bar and a frame-side-mounted 5th wheel hitch. Minor drilling is required, and a downloadable installation guide is available.
