What does the piggyback reservoir do?

The piggyback reservoir holds extra oil, which helps keep the shock cooler under heavy use. This allows for more consistent damping performance and can help prevent shock fade during long or demanding off-road runs.

Can this shock be rebuilt?

Yes, this FOX coilover shock is designed to be rebuildable and serviceable. This means you can maintain it over time to ensure it continues to perform at its best, and custom valving options are available.

What is the spring rate for this coilover?

This coilover shock comes with a 50/70 spring rate. This is a common dual-rate setup that offers a good balance between ride comfort and off-road capability.
