Fine-Tune Your Bypass Shock Travel With a Direct-Fit Replacement Stem
This FOX 2.0 Factory Series stem is a direct-fit replacement component for FOX internal bypass shocks, measuring 9.610 inches extended and 7.580 inches compressed. It is engineered to work with FOX's internal bypass technology, which allows oil to flow around the piston at certain points of the stroke while building pressure at others, delivering the feel of nearly endless suspension travel. Paired with FOX's Ride Zone technology, a race-developed shock piston, and Dual Speed Compression adjustment, this stem helps you fine-tune your suspension for weight, terrain, and speed.
