Fox Racing Shocks 981-20-013-3 Factory Race 2.0 x 9.4 Smooth Body Piggyback Shock Class 9/11 Rear 8.0 Reservoir

The Fox Racing Shocks 981-20-013-3 is a Factory Race Series 2.0 smooth body piggyback shock absorber engineered specifically for Class 9 and Class 11 rear suspension applications in off-road racing. With a 9.4-inch stroke and an 8.0-inch remote reservoir, this shock is built to handle the punishment of competitive desert and short-course racing while delivering consistent, controlled damping performance.

Fox's Factory Race Series shocks feature a 2.0-inch diameter body constructed from high-strength aluminum, offering superior heat dissipation and reduced unsprung weight compared to steel alternatives. The smooth body design eliminates external reservoirs mounted at the shock body, providing a clean, snag-free profile ideal for tight suspension packaging in race buggies. The piggyback reservoir increases oil and nitrogen gas volume, dramatically reducing heat buildup and fade during extended high-speed runs.

Key Features:

• 2.0-inch smooth body shock absorber designed for Class 9 and Class 11 rear applications
• 9.4-inch stroke for extended wheel travel in off-road race configurations
• 8.0-inch piggyback reservoir expands fluid capacity and reduces shock fade
• High-flow, velocity-sensitive damping valving optimized for race performance
• Lightweight aluminum construction for reduced unsprung weight
• Nitrogen-charged with internal floating piston (IFP) to prevent aeration and cavitation
• Application-specific tune developed for Class 9/11 race vehicles
• Rebuildable and re-valvable for ongoing race tuning

Designed and tuned specifically for Class 9 and Class 11 off-road racing, this shock delivers the precise, race-ready damping characteristics that Fox Racing Shocks is renowned for on the world's toughest courses. As a rebuildable unit, it offers long-term value and the ability to dial in valving as race conditions evolve.
