Suncore's 109G-14-R-PAIR Passive Air Shock Absorbers Conversion Kit changes out the expensive electronic air shocks with passive shocks for your Z55 Auto Ride Suspension. These Passive Air Shock Absorbers fit directly where your old electronic shocks mounted, and include a pre-installed bypass to keep your suspension warning lights off after the installation. Upper and lower bushings are included with this air shock, and everything fits into place exactly as the OEM air shock would.
