Big shocks can handle harder work, while staying cooler, for longer. The 2.5-inch aluminum shock bodies have 23% more surface area compared to a 2.0-inch body, allowing more heat to dissipate more quickly. This keeps the temperature of the shock oil in check and helps minimize shock fade during long days on rough trails.

Hydraulic Top Out (HTO) is the latest in position-sensitive damping technology from FOX, utilizing trickle down technology from our internal bypass Factory Race series shocks, but in a more simplified design.

2.5 Performance Series shocks are designed with trickle-down technology from Performance Elite Series. A more robust monotube utilizes upgraded internals, without including unnecessary features. We built 2.5 Performance Series shocks with an OEM-inspired seal pack, a threaded bearing cap, and an aluminum internal floating piston. This simple shock architecture means greater durability and long-term reliability, without the hassle.

2.5 Performance Series are tailored specifically to the vehicle you drive. FOX Ride Engineers spend considerable time with each application to evaluate the ride, optimize valving and validate performance both on and off-road.

Custom shock valving provides the driver with superior on-road comfort in all load conditions while retaining damping capacity off-road. A composed vehicle body inspires driver confidence, letting drivers push faster through low-speed bumps and washboard roads.
