Fox Racing Shocks 981-25-406-L Factory Race 2.5x18 External Bypass 3-Tube Piggyback Shock Left

The Fox Racing Shocks 981-25-406-L is a Factory Race Series 2.5 x 18 External Bypass Piggyback Shock designed for the left-side application in high-performance off-road and racing environments. Built to withstand the punishment of extreme terrain, this shock absorber features a 2.5-inch diameter body and 18-inch stroke, delivering superior damping control and heat dissipation where stock shocks simply cannot compete.

Key Features:

• 2.5" Shock Body – Large-diameter aluminum body provides increased oil volume for reduced fade and improved thermal management during extended off-road use
• 18" Stroke – Long travel stroke engineered for maximum wheel articulation on demanding trails and race courses
• 3-Tube External Bypass Design – Three bypass tubes allow precise, position-sensitive damping tuning, controlling compression and rebound characteristics at specific points in the shock's travel
• Piggyback Reservoir – Integrated remote reservoir increases oil and nitrogen gas capacity, reducing heat buildup and maintaining consistent performance under repeated hard hits
• Left-Side Application – Specifically designed and valved for left-side installation to ensure proper performance and geometry
• Rebuildable and Serviceable – Full rebuild and service capability extends the life of the shock and allows maintenance after heavy use
• Custom Valving Options Available – Can be revalved to match specific vehicle weight, terrain, and driver preference
• High-Quality Seals and Internals – Fox's race-proven internal components deliver long service life and consistent damping performance

Fox Factory Race Series shocks are the choice of professional off-road racers competing in events like Baja, King of the Hammers, and desert racing circuits worldwide. The external bypass system allows damping to be tuned zone-by-zone throughout the shock's travel, offering a level of precision unmatched by standard monotube or twin-tube designs. Whether you're building a dedicated race truck or a serious off-road performance vehicle, the Fox 981-25-406-L delivers race-winning damping technology in a rebuildable, field-serviceable package.
