What makes the JM92 oil special for off-road racing?

JM92 MIL-SPEC oil is developed specifically for off-road racing conditions. This means it's formulated to maintain consistent viscosity and performance under extreme temperatures and pressures encountered during demanding off-road use.

Can I service or rebuild this shock myself?

Yes, this FOX Factory Race shock is designed to be owner serviceable and rebuildable. This allows for routine maintenance and the ability to customize the valving to your specific needs.

What is the benefit of the piggyback reservoir?

The external piggyback reservoir increases the shock's oil capacity and helps dissipate heat more effectively. This leads to more consistent damping performance, especially during prolonged or aggressive use, and helps prevent shock fade.

About this part

Product Details

When you're pushing your vehicle to its limits on challenging terrain, whether it's a high-speed desert run or a technical rock crawling ascent, having reliable suspension is key. The FOX Factory Race 2.5 x 8 Coilover Piggyback Shock is built to handle that kind of punishment, offering consistent damping performance and the right control to keep your tires planted and your ride manageable.

This shock absorber is a well-built piece designed for serious off-road use. It features a 2.5-inch diameter body and an 8-inch stroke, providing ample travel for various conditions. The shaft is made from 17-4 H900 hard chrome plated stainless steel, which is strong and resists corrosion. Inside, it uses JM92 MIL-SPEC oil, a specialized fluid developed specifically for the demands of off-road racing. The external piggyback reservoir allows for increased oil capacity and cooling, which helps maintain consistent damping performance under heavy use. Plus, the entire assembly is protected by a proprietary Cerakote ceramic coating over a zinc-plated basecoat, offering robust defense against the elements and impacts.

What's great about these shocks is that they are owner serviceable and rebuildable. This means you can maintain them yourself or have them custom valved to perfectly match your driving style and vehicle setup, ensuring you get the most out of your suspension over the long haul. All the CNC machined aluminum components are black anodized for a clean look and added durability.
