Arnott Industries Air Spring to Coil Spring Conversion Kit P/N:C-2137
Retire a failing GM air-ride setup for good with the Arnott Industries Air Spring to Coil Spring Conversion Kit (P/N: C-4424, also written C4424) — a complete front and rear kit that transforms the factory air suspension into a passive steel coil-spring system. It's designed for short-wheelbase GMT K2UC/UG models and drops in as a direct-fit replacement for the 2015-2020 Cadillac Escalade, 2015-2020 Chevrolet Tahoe, and 2015-2020 GMC Yukon (see the "Vehicles it fits" section for engine-level details).
If a worn or leaking factory air suspension is the issue, this kit provides a full mechanical conversion to coil springs. Because it replaces both the front and rear units, install it as a complete set for balanced ride height and handling. Consult the vehicle service information for the correct fasteners and whether any originals may be reused.
