Fox Racing Shocks 981-30-415-R Factory Race External Bypass Piggyback Shock - 3.0x18 4-Tube Right

The Fox Racing Shocks 981-30-415-R is a Factory Race Series 3.0 x 18 External Bypass Piggyback Shock designed for serious off-road racing and high-performance applications. Built to handle the extreme demands of desert racing, rock crawling, and competitive off-road events, this right-side shock delivers superior damping control and thermal management where stock or standard aftermarket shocks simply cannot keep up.

The 4-tube external bypass design allows damping forces to be tuned independently across the shock's travel range—providing a compliant, controlled ride over small trail chop while firmening up progressively as suspension travel increases. This design is a hallmark of professional-grade race shocks, separating bypass technology from conventional monotube or twin-tube units.

The 3.0-inch main body houses a large-diameter piston and increased fluid volume, reducing heat buildup during extended high-speed use. The integrated piggyback reservoir further increases oil and nitrogen gas capacity, extending fade-free performance during the most punishing conditions.

Key Features:

• 3.0" body diameter with 18" travel for maximum wheel movement and control
• 4-tube external bypass configuration for fully adjustable, position-sensitive damping
• Piggyback reservoir increases fluid volume for heat dissipation and fade resistance
• Rebuildable and serviceable — designed for long-term race use and field maintenance
• Custom valving options available to match specific vehicle weight, terrain, and driving style
• High-strength aluminum body construction for reduced unsprung weight
• Right-side specific orientation
• Fox Racing Shocks' race-proven sealing system for consistent, leak-free performance

As a fully rebuildable unit with custom valving capability, the Fox 981-30-415-R is a long-term investment for racers and serious off-road enthusiasts who demand the highest level of suspension performance and tunability.
