Fox Racing Shocks 981-20-052 Performance Elite 2.0 X 16.0 Air Shock

The Fox Racing Shocks 981-20-052 Performance Elite 2.0 x 16.0 Air Shock is a high-travel, nitrogen-charged off-road shock absorber engineered for serious competition and extreme off-road builds. Featuring a 2.0" body diameter and 16" of travel, this air shock is purpose-built for rock crawlers, prerunners, and other high-performance off-road vehicles that demand maximum suspension travel and tuneability.

Key Features:

• Infinite Spring Rate Adjustability: Nitrogen charge pressure can be varied between 10–500 PSI to dial in the precise spring force needed for your application — no coil spring required
• Hollow Chromoly Shaft: The 4130 hollow chromoly steel shaft is incredibly strong yet lightweight, reducing unsprung weight without sacrificing durability
• Race-Proven Performance Damping: Uses the same damping technology found throughout the Performance Elite Series, ensuring consistent valving performance and familiar serviceability
• Zinc-Plated Seamless Alloy Body: Corrosion-resistant construction stands up to mud, water, and trail abuse
• 16" of Suspension Travel: Extended travel design ideal for competition rock crawlers and long-travel custom suspension systems
• Standard Valving: Ships with 40 compression / 90 rebound standard valving; can be revalved by any authorized Fox service center
• Fully Rebuildable & Serviceable: Like all Fox Performance Elite shocks, this unit can be rebuilt and revalved to extend its service life

Fox air shocks replace traditional coil springs with pressurized nitrogen, allowing builders to fine-tune ride height and spring rate on the fly. To calculate spring force, simply multiply the PSI by 1.2 — for example, 200 PSI delivers approximately 240 lbs of spring force. Always charge with dry nitrogen; never use compressed air, as it introduces moisture that can cause internal corrosion.

The Fox Racing Shocks 981-20-052 is an ideal choice for competition builds where long travel, lightweight components, and reliable off-road damping performance are non-negotiable.
