Remark :

Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will fitting a UMW749 change my diff feel?

The shaft itself is a mechanical link but pairing it with recommended diff outputs and hexes can alter overall feel by improving stability and power transfer.

What maintenance should I perform after racing?

After each session clean the shaft, check for wear or burrs, and lightly lubricate moving interfaces to prevent corrosion and binding.

Are there setup tips for low grip events?

Use narrower pill settings, tune diff and tyre choice, and consider the UMW748 and UM773 parts to help the car settle on low grip layouts.
