Product Details
The 17-4 H900 hard chrome plated stainless steel shaft on this Fox Factory Race 2.5 X 18 External Bypass shock is built to handle the extreme demands of off-road racing. This shock is designed to provide consistent damping performance and suspension control, whether you're navigating rough desert terrain or tackling challenging rock climbs. The 3-tube external bypass design allows for a wide range of adjustability, giving you precise control over your suspension's behavior in various conditions.
This shock features a proprietary JM92 MIL-SPEC oil, specifically developed for the rigors of off-road racing, ensuring reliable performance under high stress. The components are CNC machined from aluminum and finished with a black anodized coating for durability and a clean look, while the entire assembly is protected by a new proprietary Cerakote ceramic coating over a zinc plated basecoat, offering robust resistance to the elements. Because it's owner serviceable and rebuildable, you can maintain its peak performance over time, and custom valving options are available to fine-tune it to your specific needs.
This is a single (left side) shock absorber. For optimal performance and balance, it's recommended to pair it with a matching right-side shock and ensure your vehicle's suspension system is properly set up to take advantage of its capabilities. Refer to the manufacturer's installation instructions for detailed guidance.
