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\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\u003e17-4 H900 hard chrome plated stainless steel shaft\u003c\/li\u003e\n  \u003cli\u003eBlack Anodized CNC Machined Aluminum Components\u003c\/li\u003e\n  \u003cli\u003eOwner serviceable and rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe FOX Factory Race 2.5 x 12 Coilover Piggyback Shock is engineered for demanding off-road applications where suspension control, consistent damping, and serviceability are essential. Part number FOX981-25-113 uses FOX internal bypass technology to manage damping throughout the shock stroke, helping provide controlled suspension response over high-speed terrain, technical trails, and changing obstacles.\u003c\/p\u003e\u003cp\u003eIts ride-zone performance combines a race-developed piston, internal bypass, and Dual Speed Compression adjustment to help fine-tune the shock for vehicle weight, terrain, and driving speed. The piggyback reservoir supports consistent performance during extended, high-demand use, while the robust aluminum body and 7\/8-inch shaft are designed to withstand harsh off-road conditions. Custom valving options are available for applications requiring more specific suspension tuning.\u003c\/p\u003e\u003cp\u003eFOX builds this serviceable and rebuildable shock with a proprietary Cerakote protective ceramic coating over a zinc-plated basecoat, black-anodized CNC-machined aluminum components, and a 17-4 H900 hard-chrome-plated stainless steel shaft. JM92 MIL-SPEC oil, developed specifically for off-road racing, supports reliable damping performance across demanding conditions. The FOX Factory Race 2.5 x 12 Coilover Piggyback Shock is intended for automotive off-road suspension applications; verify vehicle fitment, mounting configuration, spring requirements, and valving before installation.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications \u0026amp; Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: FOX\u003c\/li\u003e\n\u003cli\u003ePart Number: FOX981-25-113\u003c\/li\u003e\n\u003cli\u003eProduct Type: Coilover piggyback shock\u003c\/li\u003e\n\u003cli\u003eApplication: Automotive off-road suspension\u003c\/li\u003e\n\u003cli\u003eShock Configuration: 2.5-inch race shock with piggyback reservoir\u003c\/li\u003e\n\u003cli\u003eAdjustment: Dual Speed Compression adjustment\u003c\/li\u003e\n\u003cli\u003eShaft Construction: 17-4 H900 hard-chrome-plated stainless steel\u003c\/li\u003e\n\u003cli\u003eServiceability: Owner serviceable and rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eOne FOX Factory Race 2.5 x 12 Coilover Piggyback Shock.
