FOX Factory Race Series 3.2 Internal Bypass shocks for the LC250, GX550, and 4Runner chassis deliver velocity and position-sensitive damping technology, Dual Speed Compression Evolution (DSC EVO) 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 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. Type II anodization prevents corrosion and wear of the 3.2-inch diameter aluminum bodies. Finned reservoirs increase oil capacity, house an IFP, and feature a DSC EVO adjuster. DSC EVO utilizes Variable Valve Control (VVC) on the high-speed circuit. VVC doesn't add preload to the shim stack to adjust high-speed damping. The result is more comfort, independent high and low-speed circuits, and increased capacity for big hits. Add clicks of high-speed compression without sacrificing small-bump sensitivity.FOX 3.2 shocks with Internal Bypass provide the support, adjustment, and confidence you need while driving at speed. Experience race-bred performance next time you leave the pavement.
