Fox Racing Shocks 981-20-049 Performance Elite 2.0 x 10.0 Nitrogen Air Shock

The Fox Racing Shocks 981-20-049 is a Performance Elite 2.0 x 10.0 Air Shock built for serious off-road and competition applications. Part of FOX's Performance Elite Series, this 2.0" diameter air shock delivers race-proven damping technology in a lightweight, field-serviceable package — making it a top choice for rock crawlers, off-road racers, and custom suspension builds.

Unlike traditional coil spring shocks, the air shock design uses pressurized nitrogen as both the spring medium and gas charge. This allows for infinite spring rate adjustability simply by varying the nitrogen pressure, giving builders and racers the ability to dial in ride height, preload, and load capacity without swapping springs. FOX recommends filling with nitrogen only — never compressed air — to prevent internal corrosion.

Key Features:

• 2.0" body diameter with 10.0" of travel for a compact, versatile shock package
• Nitrogen air spring — infinitely adjustable spring rate by varying pressure (10–500 PSI)
• Hollow chromoly shock shaft — incredibly strong yet lightweight for reduced unsprung weight
• Race-proven Performance Elite damping technology — same valving and service platform as other FOX Performance Elite Series shocks
• Zinc-plated seamless alloy body — exceptional corrosion resistance for harsh environments
• Fully serviceable design — can be rebuilt and revalved through authorized FOX service centers
• Ideal for competition rock crawlers and custom off-road suspension setups

The FOX Performance Elite Series air shock shares the same service and valving platform as the broader Performance Elite lineup, making tuning and maintenance straightforward. Whether you're building a dedicated race rig or a trail-ready crawler, the 981-20-049 provides the durability, adjustability, and FOX-quality damping that serious off-road builds demand.
