Product Details

When you're pushing your vehicle to its limits off-road, whether that's flying over desert terrain or navigating challenging rock climbs, you need suspension that can handle the punishment and keep you in control. This FOX 3.5 Factory Series Bypass Shock is built for those demanding situations, offering advanced damping performance and suspension control tailored to your specific needs.

This shock features a durable, zinc-plated seamless alloy body designed to withstand harsh environments. The 1-inch diameter shaft is made from industry-leading 17-4 H900 stainless steel, known for its strength and corrosion resistance. Inside, FOX Racing Oil is used, formulated for ultimate performance. All the machined aluminum components are black anodized for a solid finish and added durability. Because it's a bypass shock with custom valving, it allows for precise tuning of compression and rebound damping – this specific unit has 3 compression and 2 rebound tubes, giving you a wide range of adjustability to dial in the ride for your vehicle and driving style. It's also rebuildable and serviceable, meaning you can maintain its performance for years to come.

This shock is designed for custom valving, allowing you to specify the exact damping characteristics you need. It's a substantial upgrade for serious off-road applications where consistent, reliable suspension performance is critical. Ensure you consult the manufacturer's documentation for installation details and any specific requirements for custom valving setup.
