FOX Factory Race Series 2.5 Internal Bypass shocks deliver velocity- and position-sensitive damping with Dual Speed Compression (DSC) adjustment and high-speed-ready performance in a bolt-on kit.
Patented Internal Bypass technology creates multiple zones of damping control for a more comfortable, controlled ride. The design provides progressive force to control hard bottom-outs, prevent harsh top-outs, and offer an initial catch on landings. In the ride zone shock fluid bypasses the main piston through a series of bleed holes; beyond the ride zone the bleed holes terminate and fluid is forced through the main piston for increased damping.
These shocks are engineered to provide added support and confidence when driving at speed through rugged terrain while maintaining a comfortable on-road feel.
*Compatible with Toyota 4Runner. Bolt-on kit; final setup should be dialed in using the DSC adjuster to match load and driving conditions.
