M&P USA GM Z55 2-Axle Shock & Ride Height Bypass Kit with Pigtails for 2005-2012 Cadillac, Chevrolet & GMC

The M&P USA Z55 2-Axle MagneRide Bypass Kit converts BOTH axles of a 2005-2012 GM truck or SUV with the Z55 AutoRide system in one box, with the rear pigtails included . It lets you replace the factory GM MagneRide shocks and electronic struts, including worn-out rear air-ride shocks, with standard passive shocks or coilovers without the “Service Suspension System” warning or fault codes. You get 4 shock simulators, 4 ride height sensor simulators, and 2 rear pigtails with waterproof heat-shrink crimp connectors. The front plugs straight into the factory connectors; the rear air-ride connectors use the included pigtails, which are spliced in. It fits 2005-2012 Cadillac Escalade, Chevrolet Tahoe and Suburban, and GMC Yukon and Sierra Denali models with the Z55 package.

GM used both Z55 AutoRide and Z95 MagneRide during 2013 and 2014, and changed connectors partway through some model years, so the year alone won’t tell you which kit you need. Here’s how to check:

1. Open the glove box and find the Service Parts Identification label, a sticker covered in short 3-character codes.
2. Look for Z55 (use this kit) or Z95 (use the Z95 kit).
