Fox Racing Shocks 981-35-402-R Factory Race External Bypass Piggyback Shock - 3.5x16 5-Tube Right

The Fox Racing Shocks 981-35-402-R is a Factory Race Series 3.5" x 16" External Bypass Piggyback Shock designed for serious off-road racing and high-performance applications. Built to the exacting standards that Fox Racing Shocks is renowned for in professional motorsports, this right-side shock delivers exceptional damping control and heat dissipation under the most demanding race conditions.

The 5-tube external bypass configuration with 3/4" bypass tubes allows precise, position-sensitive damping adjustment by routing oil around the main piston at specific points in the shock's travel. This allows tuners and drivers to independently dial in low-speed compression, high-speed compression, and bottom-out resistance — critical for achieving optimal race performance over varied terrain.

The 3.5" bore piggyback reservoir provides a significantly increased oil volume compared to standard shocks, dramatically reducing heat buildup and fade during extended high-speed use. The piggyback design keeps the reservoir close to the shock body for compact packaging while still delivering the fluid capacity needed for race-level performance.

Key Features:

• 3.5" bore diameter for high oil volume and superior heat management
• 16" stroke for maximum wheel travel on race-built vehicles
• 5-tube external bypass system with 3/4" bypass tubes for position-sensitive, tunable damping
• Piggyback reservoir design for increased fluid capacity and fade resistance
• Right-side application — sold individually
• Rebuildable and fully serviceable for long service life and cost-effective maintenance
• Custom valving options available to suit specific vehicle setups and race disciplines
• Constructed from high-grade aluminum for strength and weight savings
• Nitrogen-charged for consistent, cavitation-free performance

The Fox Factory Race Series represents the pinnacle of Fox's off-road shock technology, trusted by professional racers in desert racing, rock crawling, and short-course events. The 981-35-402-R is fully rebuildable and can be revalved by Fox or authorized service centers to keep it performing race-ready for years to come.
