FOX Performance Elite 2.0 Air Shock, 14-Inch Travel, 1-1/4-Inch Shaft, Normal Valving, 40/90 - FOX981-20-051

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.

• 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 where adjustable spring control and race-proven damping are essential. By varying the nitrogen charge pressure, the spring rate can be tuned to suit vehicle weight, terrain, and driving conditions without changing conventional coil springs.

Part number FOX981-20-051 uses FOX Performance Elite damping technology, providing compatibility with established FOX service and valving procedures. The shock is rebuildable and owner serviceable, while custom valving options allow further tuning for specialized builds. A lightweight hollow shaft helps reduce unsprung weight without compromising durability in severe off-road use.
