Fox Racing Shocks 981-25-603-3 Factory Race 2.5x16 Coilover Internal Bypass Piggyback Shock with DSC Adjuster

The Fox Racing Shocks 981-25-603-3 is a Factory Race Series 2.5-inch diameter, 16-inch coilover internal bypass piggyback shock absorber featuring Fox's Digital Shock Controller (DSC) Adjuster. Engineered for serious off-road racing and high-performance applications, this shock delivers the precision damping and durability demanded by professional racers and dedicated enthusiasts.

Internal Bypass Technology:

Fox's internal bypass design allows the shock to run at a firm, controlled rate during normal travel while automatically softening as the shock approaches the end of its stroke. This provides superior bottoming resistance without sacrificing ride quality or compliance over rough terrain — a hallmark of Fox Factory Race engineering.

Key Features:

• 2.5-inch bore diameter — large-volume shock body for increased oil capacity and superior heat dissipation
• 16-inch shaft travel — extended travel for demanding off-road and racing environments
• Coilover configuration — integrates spring and damper into a single, compact, adjustable assembly
• Internal bypass design — position-sensitive damping for a plush mid-stroke feel with firm end-stroke control
• Piggyback reservoir — additional fluid and nitrogen gas volume for consistent fade-free performance during prolonged hard use
• DSC (Digital Shock Controller) Adjuster — allows precise, on-the-fly external damping adjustability without disassembly
• Rebuildable and fully serviceable — designed for long service life; can be rebuilt and revalved to extend lifespan and adapt to changing conditions
• Custom valving options available — can be spec'd or revalved to match specific vehicle weight, spring rates, and terrain requirements

Built with Fox's industry-leading quality standards, the 981-25-603-3 is constructed from high-strength materials and sealed with premium wipers and seals to withstand the harshest racing environments. Whether you're competing in desert racing, rock crawling, or demanding overland expeditions, this shock delivers the consistent, race-proven performance Fox Racing Shocks is known for worldwide.
