Air Spring Kit for Silverado & Sierra 2500 HD/3500 HD (2011–2019)

Air Spring Kit, fitment-checked

For the heavier end of the GM lineup: Rough Country 10007 is a rear air spring kit covering 2011–2019 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD in 4WD and RWD, plus the 2015 Silverado 3500. Bags support up to 5,000 lb of load for level ride height. Installation involves minor drilling, and the kit does not add towing capacity.

Trims run wide: WT, LT, LTZ, and High Country on the Chevrolet side, Base, SLE, SLT, and Denali on the GMC side, in both 4WD and RWD. The bags are double-convoluted with internal bump stops, mounted on powder-coated steel brackets and plumbed with DOT-approved line and push-to-connect fittings. A downloadable step-by-step installation guide is available for the job, which includes minor drilling. Use the fitment table to confirm your exact year, model, and drivetrain before ordering, since the 3500 listings differ slightly from the 2500 listings.
