FOX Factory Race Series 2.0 x 2.5 Bump Stop, Part Number 981-20-041

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.

• NEW proprietary Cerakote® protective ceramic coating over zinc plated basecoat
• JM92 MIL-SPEC oil developed specifically for off-road racing
• Black Anodized CNC Machined Aluminum Components
• Hard Chrome Plated 4130 Chromoly Steel Shaft
• Hard chome plated 4130 chromoly steel shaft
• Owner serviceable and rebuildable

The FOX Factory Race Series 2.0 x 2.5 Bump Stop is engineered for demanding off-road use, delivering controlled end-of-travel suspension performance when vehicles encounter hard landings, large obstacles, and aggressive terrain. FOX devotes extensive research and development to suspension components that withstand severe punishment while providing consistent damping and suspension control.

Featuring patented internal bypass technology, the FOX 981-20-041 allows oil to flow around the piston through specific portions of the stroke, then builds significant hydraulic pressure where additional support is needed. This design helps create a controlled ride zone and supports the vehicle during demanding suspension events. Custom valving options are available, allowing the bump stop to be tuned for vehicle weight, terrain, and driving speed.

The bump stop uses a durable aluminum body, a remote reservoir design, and a hard chrome-plated 4130 chromoly steel shaft for strength in harsh environments. Its race-developed internals and serviceable construction make it suitable for long-term off-road use and professional maintenance. Additional finishes and materials include a Cerakote protective ceramic coating over a zinc-plated basecoat, black anodized CNC-machined aluminum components, and FOX JM92 MIL-SPEC oil developed specifically for off-road racing.
