An optional Z55 suspension package was available on many of GM’s larger trucks. Auto Ride is GM’s trade name for its automatic load leveling suspension and computer controlled crash system. The Auto Ride system provides a smooth ride, but when the system fails it can leave a huge hole in your pocket. Grade Auto Parts offers brand new replacement passive shocks for Z55-equipped GM trucks that will maintain ride quality and handling at a much lower cost.
The factory-built Auto Ride Z55 package is a fully automatic ride control system that continuously adjusts the damping level of each of the four corners of the vehicle to deliver superior ride and ride quality. It was equipped as a standard feature on the GMC Yukon Denali and Yukon XL Denali trim levels and is available as an option on Chevrolet Suburban, Tahoe, Avalanche and other GM trucks manufactured between 2000 and 2014. On the more luxurious Cadillac Escalade and Escalade EXT SUVs, the system retained the option code Z55, but differed in name and was instead listed as “Road Sensing Suspension”.
Along with dynamic dumping mode, the Auto Ride Z55 system also features automatic load control via an air suspension system, which helps maintain the vehicle level and ride when the truck is fully loaded with cargo or passengers. Maintains quality. Because the Auto ride Z55 system is a hybrid of a dynamic hydraulic suspension and an air suspension, it is unfortunately vulnerable to wear and tear as time passes. Over time, hydraulic seals weaken, causing a loss of hydraulic pressure and a total loss of moisture at each corner, resulting in rough and bouncy driving. When the air adjustable damper part fails, your truck will often lean on one end or even just one corner. The resulting low ground clearance and vehicle imbalance will make your truck unstable and unsafe to drive. New suspension components help ensure the best handling, braking and acceleration for your vehicle.
