About this kit
4-Inch Spacer Air Spring Kit with Compressor, fitment-checked
The 100054WC build adds onboard air to the Silverado and Sierra 1500 setup: the rear air spring kit, a 4-inch 4-degree spacer set, and a wireless air bag controller kit with compressor, so pressure can be adjusted from the driver's seat. Fitment covers 2007–2018 Silverado 1500 and Sierra 1500, the 2019 Silverado 1500 LD, and the 2010–2018 Sierra. Drilling is required during installation.
Everything in the box works together: air bags with internal bump stops, powder-coated steel brackets, push-to-connect fittings, DOT-approved line, and the wireless controller and compressor that let you set rear pressure without an external air source. Supported trucks run from Silverado 1500 WT and Custom through LTZ, and Sierra 1500 SLE through Denali, plus the Silverado 1500 LD. Expect to drill during the install. Air springs level a squatting rear end under load. They do not change what the truck is rated to tow.
