Fox Racing Shocks 981-25-405-R Factory Race 2.5 x 16 External Bypass 3-Tube Piggyback Shock Right

The Fox Racing Shocks 981-25-405-R is a Factory Race Series 2.5-inch diameter, 16-inch external bypass piggyback shock absorber designed for high-performance off-road racing and competition applications. Featuring a 3-tube external bypass configuration, this right-side shock delivers precise, independently tunable damping across multiple zones of wheel travel, allowing racers and builders to dial in compression damping characteristics for varying terrain conditions.

The external bypass design routes shock fluid through adjustable bypass tubes positioned along the shock body, enabling fine-tuned control over low-speed and high-speed damping without disassembling the shock. The 2.5-inch main body provides a large fluid and nitrogen reservoir capacity to resist fade during extended, high-intensity use. The integrated piggyback reservoir further increases oil volume and heat dissipation, maintaining consistent performance lap after lap.

Key Features:

• 2.5-inch shock body diameter for increased oil capacity and thermal stability
• 16-inch travel for long-travel off-road and racing builds
• 3-tube external bypass for multi-zone, independently adjustable compression damping
• Piggyback reservoir for expanded fluid volume and improved heat management
• Right-side specific fitment for proper bypass tube orientation
• Rebuildable and fully serviceable for long-term racing use
• Custom valving options available to match specific vehicle weight, suspension geometry, and terrain
• Nitrogen-charged for consistent, aerated-fluid-free damping performance
• Machined aluminum body and components for lightweight strength

Built to Fox's exacting Factory Race standards, the 981-25-405-R is engineered for serious off-road competition including desert racing, rock crawling, and pre-runner applications where maximum suspension travel and precise damping control are essential. Fully rebuildable and re-valveable, this shock represents a long-term investment in race-proven suspension performance.
