About this kit

Air Spring Kit with Compressor, fitment-checked

Covers the 2020-2025 Chevrolet Silverado 2500 HD and 3500 HD and the GMC Sierra 2500 HD and 3500 HD, in 4WD and RWD. Bundled with the 10100 compressor, and it includes headlight adjustment brackets for 2021 models with headlight actuators. Several exclusions apply — read them before ordering.

One kit spans four trucks here, the Silverado and Sierra in both 2500 HD and 3500 HD form, across 2020-2025 in 4WD and RWD. The exclusions are the part to check: frame side mounted fifth wheel hitches and models with a rear sway bar are both out. Front and rear headlight adjustment brackets are included for 2021 models fitted with headlight actuators, which is the sort of detail that otherwise turns into a second order. The bag is double convoluted with an internal bump stop on powder coated steel brackets, with DOT approved air line and push to connect fittings. 49 lb boxed.
