Upgrade your old or worn down oil shocks to heavy-duty gas shocks from Bronco ATV and UTV Components™. These shocks are designed to come standard with 10% stiffer springs and adjustable preload for more efficient aerodynamics and faster acceleration. All Bronco shocks come with pressed NBR bushings compared to OEM shock bushings that are generally made from polyurethane that are prone to failure due to out-of-tolerance wear and fracture. Gas shocks from Bronco include springs, retainers, and bumpers ready to mount right out of the box with simple and easy installation instructions.
