Upgrade Your ULTIMA RB6 with Kyosho UM712B Suspension Arms

If you want to sharpen the performance of an ULTIMA RB6, the Kyosho UM712B Front Suspension Arm Set provides a clear upgrade path. Made for the RB6 chassis, these arms focus on long-term durability and crisper handling to support competitive driving.

Engineered for Track-Level Stability

The Kyosho UM712B suspension arms are produced to give extra strength and consistent stability. This approach reduces unwanted flex so the car responds more predictably to steering inputs, helping you place corners more accurately during club or regional events.

Suited to Serious Racing Use

From practice laps to race day runs, this suspension arm set suits committed RC racers who want reliable parts that hold up under stress. The improved construction helps maintain chassis geometry and repeatable handling on asphalt tracks.
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 the UM712B arms fit without other modifications?

The Kyosho UM712B arms are designed for RB6 chassis fitment and typically install using the stock mounting points, so no major chassis mods are needed.

How do these arms change steering feel?

By reducing flex and adding rigidity, the arms give a firmer, more direct steering response that helps when dialing in corner entry and mid-corner balance.

Are there any setup tips after fitting the arms?

After fitting, check toe and camber at ride height and run a few warmup laps to confirm handling, making small shock or toe adjustments as required.
