FOX Factory Race Series 2.5-Inch x 2.0-Inch Bump Stop, Eye-to-Eye Mount – FOX981-25-048

FOX devotes countless hours of research and development to design race-winning suspension that withstands incredible punishment and provides consistent performance you can rely on. Regardless of whether you are flying high over the desert or struggling to stick to a rock face on an off-camber climb, our shocks will give you the damping performance, suspension control and proper spring rate to get the job done. Rebuildable and serviceable. Custom valving options available. Uncompromised performance through FOX’s patented internal bypass technology delivers the feel of near-endless suspension travel. Exclusive internal bypass technology allows oil to flow around the piston at some points of the stroke – while creating humongous pressure at other points – supporting the vehicle like no other product can. Floating through terrain is accomplished with FOX’s ride zone – combining a race-developed shock piston, internal bypass and Dual Speed Compression adjustment – allowing fine tuning for weight, terrain and speed. Dominate any terrain with the brute strength of 3- and 2.5-inch aluminum bodies, cactus cooler reservoirs and 7/8” shafts with redundant seals, all proven in the harshest of environments under the toughest of conditions.

The FOX Factory Race Series FOX981-25-048 bump stop is engineered for demanding off-road applications where dependable impact control and consistent suspension performance are essential. Its eye-to-eye mounting configuration provides a secure installation format for compatible racing and performance suspension systems, helping manage hard bottom-outs and reduce harsh impact forces during aggressive driving.

FOX internal bypass technology is designed to deliver controlled damping throughout the stroke by directing oil flow around the piston at specific points while increasing pressure where additional support is needed. Combined with FOX’s ride zone, race-developed piston design, internal bypass system, and Dual Speed Compression adjustment, this bump stop supports suspension tuning for vehicle weight, terrain, and driving speed. Custom valving options may be available for specialized setups.

Built for serviceability and long-term use, the FOX981-25-048 features a durable aluminum body, a hard chrome-plated 4130 chromoly steel shaft, black anodized CNC-machined aluminum components, and redundant shaft seals. FOX JM92 MIL-SPEC oil is formulated specifically for off-road racing, while the Cerakote protective ceramic coating over a zinc-plated basecoat adds resistance to demanding environmental conditions. The unit is owner-serviceable and rebuildable, helping simplify maintenance and extend product life. Verify vehicle, suspension configuration, mounting location, and required travel before installation.
