The Kyosho UM578 - Ultima SB Front Knuckle & Hub Carrier Set is a focused upgrade for drivers wanting crisper steering and stronger front assembly performance. It helps the Ultima SB maintain better control when running on rough terrain and tight courses.

Durable Design Built for Trail and Track

Made to withstand typical off-road use, this knuckle and hub carrier set increases the strength and lifespan of the front suspension. The components are suited to both casual bashing and more serious club-level use where reliable steering response matters.

Simple Fitment with Ultima SB Chassis

Installation is straightforward and designed to match the Ultima SB series mounting points, so you can upgrade without major changes to your setup. Check alignment and fastener torque after fitting to keep handling predictable.
Remark :

They are made for the Ultima SB family. For older or modified chassis, verify the mounting pattern and clearances before installing.

What tools do I need for installation?

Basic RC hand tools such as hex drivers, pliers and a torque wrench are sufficient. Keep fasteners to the recommended torque to avoid play in the steering.

Are these suitable for racing use?

Yes, they offer improved steering precision and durability that benefit track sessions and competitive club events, while still being suitable for weekend trail runs.
