Hydra 2 Freehub Body Conversion Kit

What Our Gearhead® Experts Are Saying:

"If you want the easiest way to swap driver standards on a Hydra 2 hub, these kits are the answer. Engagement is immediate, installation is clean, and the hub feels brand new afterward."

Hydra 2 freehub kits are engineered to provide a seamless way to replace or convert freehub bodies while preserving the ultra-fast engagement Hydra 2 hubs are known for. Each kit arrives fully assembled with pawls and springs, minimizing service time and eliminating the need to source small internal parts separately.

Available in HG, XD, MS, and single speed options, these kits support a wide range of drivetrain configurations across trail, enduro, and gravity builds. Certain kits include a matching driveside endcap for full compatibility, while others require a specific endcap to be ordered separately depending on the existing hub configuration.

Recommended for riders and mechanics performing drivetrain conversions, hub refreshes, or emergency replacements, Hydra 2 freehub kits deliver factory-level performance, unmistakable engagement, and long-term reliability with minimal downtime.
