Product Details

Arnott AS-2190 is a rear air shock absorber designed to keep the rear air leveling system operational on select GM full-size cars. The unit uses a twin-tube, hydraulic internal damper with progressive spring characteristics to support controlled rear suspension response. It also includes springs and spring isolators, along with a protective aluminum can for added durability in everyday driving conditions. This part number, AS-2190, is a direct replacement option for applications where the original rear air shock has worn out or the air leveling system is no longer maintaining proper ride height.

This part cross-references General Motors 19257784 and 19299843 for the same application.
