Fox Racing Shocks 981-25-402-R Factory Race External Bypass Piggyback Shock - 2.5x10 3-Tube Right

The Fox Racing Shocks 981-25-402-R is a Factory Race Series 2.5-inch x 10-inch external bypass piggyback shock absorber (right-side application) engineered for serious off-road competition and high-performance trail use. Fox's external bypass platform has accumulated decades of race wins across the globe, and this latest generation refines the proven externally adjustable, position-sensitive damping architecture to deliver elevated performance, enhanced durability, and a more streamlined build.

The three-tube external bypass design gives the shock precise, tunable damping at multiple points throughout the stroke — allowing damping forces to be dialed in for specific terrain, vehicle weight, and driving speed. The piggyback reservoir increases oil and nitrogen capacity, reducing heat buildup and maintaining consistent damping performance during extended high-intensity use.

Key Features:

• 2.5" smooth-bore zinc-plated seamless steel body for long-lasting corrosion resistance and structural integrity
• Dual-coated body finish featuring proprietary FOX Grey Cerakote® protective ceramic coating over a zinc-plated basecoat for superior corrosion resistance and durability
• 7/8" hard chrome-plated, heat-treated alloy steel shaft for exceptional wear and corrosion resistance
• Black-anodized CNC-machined 6061-T6 billet aluminum components for precision fit and reduced weight
• 3-tube external bypass configuration for position-sensitive, externally adjustable damping tuning
• Piggyback reservoir increases fluid and nitrogen volume for consistent fade-free performance
• Rebuildable and fully serviceable construction for long service life
• Custom valving options available to suit specific build and performance requirements
• Right-side specific mounting orientation

The Fox 981-25-402-R is a rebuildable, race-pedigree shock built for demanding off-road applications where precision damping control and long-term reliability are non-negotiable. Custom valving options make it adaptable to a wide range of builds and performance goals.
