Improve Steering Performance on the Ultima SB

The Kyosho UM578 - Ultima SB Front Knuckle & Hub Carrier Set is an effective upgrade to sharpen steering control and increase front-end durability. It helps the Ultima SB track better through uneven sections and turns.

Robust Design for Off-Road Use

This knuckle and carrier set is aimed at reducing common wear points and delivering steadier handling over time. Its build quality supports regular off-road running and the occasional competitive outing.

Fitting and Setup Advice

The UM578 parts fit into the Ultima SB platform without major modification. After fitting, perform basic setup checks like toe and steering endplay to ensure predictable handling on the track.
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 these compatible with aftermarket uprights?

They are intended for standard Ultima SB uprights. If you use aftermarket uprights, verify geometry and mounting points before fitting.

How will this affect handling on hardpack?

The set tightens steering feel and reduces unwanted flex, which can improve precision on hardpack surfaces as well as loose tracks.

Can I service these parts with standard spares?

Routine servicing uses common RC spares like bearings and fasteners. Keep spare small parts on hand to minimise downtime between sessions.
