Description
The FOX® Factory Race 2.5 X 12 Coilover Piggyback Shock (P/N 981-25-113) is a 2.5-inch-body coilover shock with a piggyback reservoir and 12 inches of travel, providing a primary means to suspend the vehicle with adjustable preload and dual-rate spring crossover rings.
IMPORTANT: This is a piggyback-reservoir coilover — the reservoir is mounted directly to the shock body rather than remote-mounted via hose. It shares identical travel and core specifications with FOX® P/N 981-25-108, the same Factory Race 2.5 X 12 Coilover in a Remote Reservoir configuration — confirm which reservoir mounting style fits your application’s available clearance before ordering, as the two are not interchangeable. The coil spring is not included and must be matched to your application’s spring rate.
Factory Race Series coilover shocks are the foundation of race-winning suspension, providing a primary means to suspend the vehicle paired with adjustable preload and dual-rate spring crossover rings to dial in the perfect ride.
The piggyback reservoir design mounts the reservoir directly to the shock body rather than via a remote hose, offering a more compact package for applications with limited mounting space while still providing increased oil volume over a standard emulsion shock.
The shock body is finished in FOX Grey Cerakote®, a proprietary protective ceramic coating for corrosion and abrasion resistance, and uses a wire ring bearing design at the mounting points. FOX® backs this shock with its official limited warranty; full warranty terms are available from FOX® directly.

This shock is a universal application component sold by travel length, body diameter, and reservoir style rather than by specific vehicle fitment. Confirm your application’s mounting clearance for the piggyback reservoir and required travel (12″) before ordering — the remote reservoir version (P/N 981-25-108) is not a substitute for this listing.
