Product Details
When you're pushing your vehicle to its limits off-road, whether that's navigating rough desert terrain or tackling steep rock climbs, having suspension that can keep up is crucial. This FOX 4.0 Factory Series bypass shock is built to handle that kind of punishment and deliver consistent performance when you need it most.
This shock features a 4.0-inch diameter body and a 16-inch stroke, giving you ample travel. The external bypass design allows for precise tuning of compression and rebound damping with 3 compression and 2 rebound tubes, letting you dial in the suspension's response to different terrain and driving styles. The 1-1/8 inch shaft is made from strong 17-4 H900 stainless steel, known for its durability. All the aluminum components are black anodized and CNC machined for a precise fit and finish, and the seamless alloy body is zinc plated for corrosion resistance. It uses a specialized FOX Racing Oil formulated for peak performance.
This shock is rebuildable and serviceable, meaning you can maintain it for long-term use. Custom valving options are also available if you need to fine-tune the damping even further for your specific application. This is a serious piece of suspension hardware designed for those who demand the best performance from their off-road vehicle.
