Fox 4.0 Factory Race Shaft 5-Tube External Bypass 18in Piggyback Shock - Right

Fox is known for building race-winning suspension systems that can handle serious punishment and deliver reliable performance. This 4.0 Factory Race Shaft 5-Tube External Bypass Piggyback Shock is a prime example, designed to give you the damping control and suspension performance needed whether you're hitting jumps in the desert or navigating tough off-road terrain.

This shock features a 17-4 H900 hard chrome plated stainless steel shaft for durability. It uses JM92 MIL-SPEC oil, which is specifically developed for the demands of off-road racing, ensuring consistent performance even under extreme conditions. The components are CNC machined from aluminum and finished with a black anodized coating, while the entire shock body benefits from a new proprietary Cerakote protective ceramic coating over a zinc plated basecoat, offering robust protection against the elements. This shock is also owner serviceable and rebuildable, allowing for custom valving options to fine-tune your suspension setup.

Because this is a high-performance component, custom valving options are available to tailor the shock's response to your specific vehicle and driving style. It's designed to be rebuilt and serviced, meaning you can maintain its performance over the long haul.
