About this kit
Air Spring Kit, fitment-checked
This Rough Country air spring kit (100074) suits 2011-2019 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD trucks running anywhere in a 0-7.5 inch lift range. A 4 inch, 4 degree spacer kit ships with it. Note that it does not add towing capacity, and minor drilling is required to mount the brackets.
Air springs handle the load here: double convoluted bags rated to support up to 5,000 lbs, so a loaded 2011-2019 Silverado or Sierra HD sits closer to level under a trailer. The kit covers trucks from stock height through 7.5 inches of lift and includes powder-coated steel brackets, DOT-approved airline, and 1/4 inch push-to-connect fittings. An onboard compressor and wireless controller are listed as optional. Coverage is 2 Year Limited Warranty on Compressor & Limited Lifetime on Air Springs. Shipping weight: 40.0 lb.
