Fox® 883-09-141 - 3.0 Factory Series Rear Quick Adjustable Bypass Shock Absorbers

Position-sensitive External Bypass technology allows separate adjustment of the shock's compression and rebound damping at different stages of suspension travel. This provides the ultimate control in fine-tuning the vehicle's ride to maximize control, small bump compliance and comfort while preventing harsh bottom-outs. The Factory Race Series 3.0 External Bypass shocks feature four adjustable bypass zones and are coupled with QAB adjusters for quick and easy adjustment.

FOX Quick Adjust Bypass (QAB) allows you to quickly and easily adjust bypass circuits by hand, with definitive clicks at every half turn, making tracking adjustments easy. No tools necessary. The Factory Race Series 3.0 External Bypass QAB's can be set to match the Gen 2 Raptor's stock ride quality and add the ability to increase compression and rebound damping by up to 50%.

Developed for and by off-road racing's top athletes to handle the most extreme racing conditions, the External Cooling System (ECS2) is designed to maximize cooling efficiency and provide sustained, fade-free performance. Internal and external extruded aluminum fins increase cooling surface area and facilitate heat dissipation. Forced, unidirectional fluid circulation moves oil through the entire cooler to maximize cooling efficiency. This race-winning technology will keep your shocks cool and performing their best all day long. The Factory Race Series Gen 2 Raptor upgrade kit's ECS2 coolers mount through the inner fender wells and bed, requiring minor drilling.
