What makes this coilover owner serviceable and rebuildable?

This means you can perform maintenance and repairs yourself. The design allows for disassembly to clean, replace seals, or recharge with nitrogen, extending the life of the shock and allowing you to fine-tune its performance.

What is the purpose of the remote reservoir?

The remote reservoir holds extra oil and nitrogen, which helps to keep the shock cooler during extended use or high-impact situations. This prevents shock fade and maintains consistent damping performance.

What kind of oil is used in this shock?

It uses JM92 MIL-SPEC oil, which is a specialized fluid developed specifically for the harsh demands of off-road racing. This oil is designed to maintain its viscosity and performance characteristics under extreme temperatures and pressures.

About this part

Product Details

Fox is known for putting in serious time on research and development to create suspension parts that can handle a lot of abuse and still perform reliably. This 2.5 Performance Elite Series coilover shock is built with that same dedication, designed to give you the damping control and spring rate you need whether you're hitting jumps or navigating tough terrain.

This coilover features a 7/8 inch hard chrome plated steel shaft for durability and a zinc plated seamless alloy body that's built to last. The black anodized CNC machined aluminum components add to its robust construction. It uses JM92 MIL-SPEC oil, which is specifically developed for the demands of off-road racing, ensuring consistent performance even under extreme conditions. A key advantage is that this shock is owner serviceable and rebuildable, meaning you can maintain it yourself to keep it performing at its best for a long time.

This is a complete coilover assembly, meaning it includes the shock, spring, and reservoir all in one unit, simplifying installation. It's designed to be a direct replacement for many applications, but always check fitment to be sure. Because it's owner serviceable, you can perform routine maintenance or rebuilds yourself, saving on future service costs and keeping your suspension dialed in.
