What does 'Internal Bypass' mean for this shock?

An Internal Bypass shock has internal passages that allow fluid to bypass the main piston at certain points in its travel. This provides position-sensitive damping, meaning the shock can offer softer damping in the initial travel and firmer damping as it gets compressed further, helping to prevent bottoming out.

How does the DSC adjuster work?

The DSC (Dual Speed Compression) adjuster allows you to independently tune both high-speed and low-speed compression damping. High-speed compression affects how the shock reacts to rapid impacts, like hitting a bump, while low-speed compression influences body roll and weight transfer during slower maneuvers like cornering.

Can this shock be rebuilt?

Yes, this FOX coil-over shock is designed to be rebuildable and serviceable. This means you can replace seals, oil, and other components to maintain its performance over time, rather than needing to replace the entire unit.

Product Details

FOX has built a reputation for developing suspension systems that can handle extreme conditions and deliver reliable performance, whether you're hitting jumps in the desert or navigating tough off-road terrain. This 2.5 Factory Race Series coil-over shock is designed to provide the damping control and spring rate you need to tackle demanding situations.

This coil-over is rebuildable and serviceable, meaning you can maintain it for long-term use. It features custom valving, tailored to your specific needs, and an Internal Bypass design that offers position-sensitive damping. The piggyback reservoir holds extra oil to help keep the shock cool under heavy use, and the DSC (Dual Speed Compression) adjuster allows you to fine-tune the compression damping at both high and low speeds, giving you precise control over your suspension's response.

This shock uses a 7/8 inch shaft and is designed for applications where precise suspension tuning is critical. It's a solid option for serious off-road builds where consistent performance and adjustability are key.
