FAQ

Upgrade the Ultima SB front end

The Kyosho UM578B Front Knuckle & Hub Carrier Set strengthens the steering assembly of the Ultima SB to give cleaner steering inputs and steadier behaviour through corners. These front-end parts help keep alignment and suspension action consistent, which supports repeatable lap times and smoother trail runs.

Performance reasons to fit the UM578B

With accurate machining and robust construction, the knuckles and carriers reduce unwanted flex and distribute impact forces more evenly. This results in less component wear and a more predictable steering feel, useful for both club racing and casual off-road driving alike.

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.

Are replacement parts available if I damage a knuckle?

Replacement knuckles and carriers can be sourced using the part designation; keep the model number handy when ordering to ensure correct fitment for your Ultima SB.

How tough are these parts in crashes?

They are designed for improved impact resistance compared to stock items, but you should inspect them after heavy impacts and replace any components that show cracking or permanent deformation.
