Arnott AS-2708 Air Suspension Shock - Rear

Rear Air Shock for GM Autoride Suspension

Arnott AS-2708 is a remanufactured rear air shock absorber for GM SUVs and trucks equipped with Autoride Suspension RPO Code Z55. It restores electronic damping and air ride function for applications such as the Cadillac Escalade, Chevrolet Tahoe, Chevrolet Suburban 1500, and GMC Yukon.

Built as a rebuilt OE-style replacement, this rear shock uses a new Goodyear-manufactured rubber air spring bladder and plugs directly into the factory electronic damping system. Arnott AS-2708 is a practical option when the original rear air shock has lost ride control, air support, or damping response.
