AS-3430 is a new, Arnott engineered, aftermarket air suspension shock for the rear of the 2000-2014 Cadillac, Chevrolet and GMC SUV's including the Escalade, Tahoe, Suburban and Yukon (SWB/LWB) with Autoride and the 2007-2014 Cadillac, Chevrolet and GMC SUV's including the Escalade, Tahoe, Suburban and Yukon (SWB/LWB) with Magneride. This new assembly is built with premium components precisely tuned to ride like the OE, premium, multi-ply Goodyear air sleeve, long-lasting O-rings and bump stop, heavy-duty crimping rings, and a diecast top mount made of aluminum. This universal shock, which fits both the left and right side, is designed and assembled in the USA and includes an upgraded harness to avoid Autoride/Magneride burnout. Arnott's replacement GMC rear air shock works with the vehicle's auto leveling functionality.
