FOX Factory Race Series 3.0 Internal Bypass shocks for the 14th generation Ford F-150 deliver position-sensitive damping technology, Dual Speed Compression (DSC) adjustment, and high-speed ready performance in a bolt-on kit. Patented Internal Bypass technology allows for multiple zones of damping control. The result is a comfortable, confident ride with increased damping force through rough terrain. Internal bypass shocks produce more force progressively to control hard bottom-outs, prevent harsh top-outs, and provide an initial catch for landing. Shock fluid bypasses the main piston through aseries of bleed holes in the ride zone. As the shock extends past the ride zone in rebound or compression, the bleed holes terminate, forcing fluid through the main piston. The Factory Race Series shocks also stay cool by utilizing a Recirculating Reservoir Bridge. The bridge circulates shock fluid between the finned external reservoir and body using checked ports. Type III anodization prevents corrosion and wear of the 3-inch diameter aluminum bodies.The DSC adjuster allows you to dial in your F-150 for load, environment, and driving style.FOX Internal Bypass shocks deliver the support and confidence you need while driving Mach-3 through rugged terrain. Experience race-bred performance next time you leave the pavement.
