Fox Racing Shocks 981-44-403-L Factory Race 4.4 x 18 External Bypass 5-Tube Piggyback Shock Left

The Fox Racing Shocks 981-44-403-L is a Factory Race Series 4.4-inch diameter, 18-inch external bypass piggyback shock absorber designed for the left-side application. Built to withstand the extreme demands of off-road racing and high-performance driving, this shock features a 5-tube external bypass configuration that precisely controls damping force at multiple points throughout the shock's travel, delivering exceptional wheel control and ride consistency over rough terrain.

The piggyback reservoir provides additional oil and nitrogen gas volume, which helps dissipate heat during extended or aggressive use — reducing fade and maintaining consistent performance lap after lap or mile after mile. The large 4.4-inch shock body maximizes oil volume and piston surface area for superior damping capability compared to standard shock designs.

Key Features:

• 4.4" bore diameter for maximum oil volume and damping force
• 18-inch stroke for extended suspension travel
• 5-tube external bypass design for multi-zone damping adjustability
• Piggyback reservoir for increased fluid capacity and heat management
• Left-side application — sold individually
• Rebuildable and serviceable for long-term race use
• Custom valving options available to suit specific racing or terrain requirements
• Nitrogen-charged for consistent, aerated-fluid-free performance
• Fox Racing quality construction with race-proven components

Engineered for competitive off-road racing, prerunning, and extreme performance applications, this Fox Factory Race shock is fully rebuildable and can be custom-valved to match your specific vehicle setup, driving style, and terrain. Whether you're building a dedicated race truck or a high-performance off-road vehicle, the Fox 981-44-403-L delivers the reliability and tunability demanded at the highest levels of motorsport.
