About this kit

Rear Air Spring Kit with Compressor, fitment-checked

No spacers in this box — just the GM heavy-duty rear air spring kit and the wireless air bag controller with onboard compressor. Rough Country 10034WC covers Silverado 2500 HD and 3500 HD and Sierra 2500 HD and 3500 HD, 2020 through 2026, 4WD and RWD. Trucks with a rear sway bar or a frame-side-mounted 5th wheel hitch will not work.

The pairing here is straightforward: bags and powder-coated brackets for the rear axle, plus an onboard compressor and wireless remote to set pressure without leaving the seat. Fitment runs 2020 to 2026 on Silverado 2500 HD and 3500 HD and Sierra 2500 HD and 3500 HD, WT and Pro through High Country and Denali Ultimate. Rear sway bar trucks and frame-side-mounted 5th wheel hitches are out. Minor drilling is required, 2021 trucks with headlight actuators use the supplied adjustment brackets, and a downloadable installation guide is available.

Priced components are sold separately here, so a worn shock or arm can be replaced on its own later.

Rough Country shares subassemblies across kits, so individual package labels can carry broader application ranges. The complete 10034WC kit fits the vehicles shown in the fitment section above.
