Good To Know

Q: Do I need to replace the outer clutch basket at the same time? A: It is good practice to inspect the outer basket whenever the inner hub is replaced, since both wear together and a grooved basket can affect clutch operation.

Q: Will this fit every Honda TRX400EX Sportrax from 1999 to 2004? A: This hub is listed for the TRX400EX Sportrax across those model years, but serial number and production changes can affect fitment, so confirm compatibility before ordering.

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