Fox Racing Shocks 981-02-396-1 Factory Race 3.5 Series 16in External Bypass Shock Custom Valving

The Fox Racing Shocks 981-02-396-1 is a Factory Race Series 3.5 external bypass shock absorber engineered for the most demanding off-road racing and competition applications. Featuring a 16-inch stroke with a 5-tube bypass configuration — 3 compression and 2 rebound bypass tubes — paired with a 1-inch diameter shaft, this shock delivers precise, progressive damping control across the full range of suspension travel.

Custom valving is set at the factory to match your specific racing application, providing tailored damping characteristics that standard shocks simply cannot offer. The bypass tube design allows the shock to transition through distinctly tuned damping zones as the suspension cycles, giving drivers confident control whether crawling technical terrain or absorbing high-speed desert whoops.
