Fox Racing Shocks 981-35-406-R Factory Race External Bypass Piggyback Shock - 3.5x16 Right

The Fox Racing Shocks 981-35-406-R is a Factory Race Series 3.5-inch diameter, 16-inch external bypass piggyback shock absorber designed for high-performance off-road racing applications. Built with a 5-tube external bypass configuration and 1-inch bypass tubes, this right-side shock delivers precisely controlled damping over the full range of suspension travel — from slow, rocky terrain to high-speed desert running.

The external bypass design allows damping force to be tuned independently at multiple points in the shock stroke, giving racers and serious off-road enthusiasts the ability to dial in exactly how the suspension behaves during compression and rebound. The integrated piggyback reservoir increases fluid and nitrogen gas volume, reducing heat buildup and fade during extended hard use.

Key Features:

• 3.5" bore diameter for maximum damping force and fluid volume
• 16" stroke external bypass configuration
• 5-tube external bypass with 1" bypass tubes for multi-zone damping adjustment
• Piggyback reservoir for increased oil and nitrogen capacity, reducing heat fade
• Fully rebuildable and serviceable for long service life and race-day reliability
• Custom valving options available to suit specific vehicle setups and racing conditions
• Right-side application — sold individually
• Designed and manufactured in the USA to Fox Racing Shocks' exacting quality standards

The Fox Factory Race Series represents the pinnacle of Fox's off-road shock technology, trusted by professional racers in events like the Baja 1000, King of the Hammers, and SCORE International desert racing. Whether building a race truck, trophy truck, or a high-performance off-road vehicle, the Fox 981-35-406-R provides the damping control and durability to compete at the highest level.
