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.\nRebuildable and serviceable. Custom valving options available.\nUncompromised 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.\n\nFloating 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.\n\nDominate 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.\n\u003cul\u003e\n  \u003cli\u003eNEW proprietary Cerakote® protective ceramic coating over zinc plated basecoat\u003c\/li\u003e\n  \u003cli\u003eJM92 MIL-SPEC oil developed specifically for off-road racing\u003c\/li\u003e\n  \u003cli\u003eBlack Anodized CNC Machined Aluminum Components\u003c\/li\u003e\n  \u003cli\u003eHard Chrome Plated 4130 Chromoly Steel Shaft\u003c\/li\u003e\n  \u003cli\u003eHard chome plated 4130 chromoly steel shaft\u003c\/li\u003e\n  \u003cli\u003eOwner serviceable and rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe FOX 2.0 Factory Series bump stop is engineered to provide reliable bottom-out control during demanding off-road driving. Designed for race vehicles, trucks, and custom suspension applications, the FOX 981-20-040 combines consistent damping performance with a durable construction that withstands repeated impacts, harsh terrain, and high-speed suspension cycling. Its pinch-mount design supports secure installation where compatible mounting hardware and vehicle clearance are available.\u003c\/p\u003e\u003cp\u003eFOX internal bypass technology helps manage damping through different portions of the stroke, allowing the bump stop to deliver controlled support as suspension compression increases. A race-developed piston, internal bypass design, and Dual Speed Compression adjustment work together to help tune performance for vehicle weight, terrain, and driving speed. The unit is owner serviceable and rebuildable, and custom valving options are available for specialized suspension setups.\u003c\/p\u003e\u003cp\u003eThe FOX 981-20-040 features a durable aluminum body, a hard chrome-plated 4130 chromoly steel shaft, redundant seals, and black anodized CNC-machined aluminum components.
