FOX Performance Elite 2.0 Air Shock, 10-Inch Travel, 1-1/4-Inch Shaft, Normal Valving, 40/90 - Part FOX981-20-049

The design of the off-road Performance Elite air shock allows for infinite adjustability of the spring rate by varying the nitrogen charge pressure. FOX's first air shock was invented by Bob Fox back in 1974 and has been highly refined in the 30-plus years we’ve been producing them. The off-road Performance Elite air shock uses the identical race-proven performance damping technology as our other Performance Elite Series off-road shocks, so servicing and valving adjustments are the same. Incredibly strong yet lightweight hollow shock shafts further reduce weight on these shocks that are ideal for competition rock crawlers. Rebuildable and serviceable. Custom valving options available.

• JM92 MIL-SPEC oil developed specifically for off-road racing
• Durable clear coated, zinc plated seamless alloy body
• Durable Clear Coated; Zinc Plated Seamless Alloy Body
• Black Anodized CNC Machined Aluminum Components
• Hard Chrome Plated 4130 Chromoly Steel Shaft
• Hard chome plated 4130 chromoly steel shaft
• Owner serviceable and rebuildable

The FOX Performance Elite 2.0 air shock is engineered for off-road competition vehicles, including rock crawlers and other demanding applications. Its nitrogen-charged air spring allows the spring rate to be adjusted without replacing a coil spring, providing a broad range of tuning options for vehicle weight, terrain, and driver preference. The shock features FOX race-proven Performance Elite damping technology, with servicing and valving adjustments supported by the same processes used across the Performance Elite off-road shock line.

Built for durability and long-term serviceability, the FOX981-20-049 uses a clear-coated, zinc-plated seamless alloy body and black-anodized CNC-machined aluminum components. A hard chrome-plated 4130 chromoly steel shaft provides strength and wear resistance, while the hollow shaft design helps reduce unsprung weight. JM92 MIL-SPEC oil, developed specifically for off-road racing, supports consistent damping performance in demanding conditions.

This FOX air shock is owner-serviceable and rebuildable, making it suitable for enthusiasts and competition teams who require ongoing maintenance and tuning capability. Custom valving options are available for applications that require more precise damping characteristics. The shock is supplied with normal valving and a 40/90 specification. Professional installation and appropriate nitrogen charging equipment are recommended. This product may expose you to chemicals known to the State of California to cause cancer or reproductive harm.
