Good To Know

Q: Will this kit fit both the FX350 and FX450? A: The kit is listed for both models across the 2017-2025 range. Confirm your model year and hub before ordering.

Q: Can I reuse my old sprocket bolts? A: Reusing stretched or corroded bolts can lead to loosening under load. Fitting a fresh rear sprocket bolt kit is the safer route when you change the sprocket.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
