The racing wheel overhauling kits are assembled with Koyo bearings.

Koyo is a Japanese manufacturer of high quality bearings mounted as standard on the main brands and almost all aftermarket wheels for racing.

Each code contains all the components necessary for revising the wheel unit, thus guaranteeing a quick and precise operation.

For front or rear wheel bearings are meant only the bearings and the dust covers for both sides of the wheel.

The kits are normally composed of two oil seals and two or three bearings.
