Performance Upgrade for Ultima SB with Kyosho UMW531B

Fit a tougher rear mount to your chassis with the Kyosho UMW531B Aluminum Rear Suspension Holder. Built for the Ultima SB series, this machined aluminium component increases structural rigidity and creates a more accurate mount point, helping to stabilise rear-end behaviour under load.

Advantages of the Aluminum Rear Holder

The UMW531B swaps a flexible stock part for a stiffer alloy unit that reduces unwanted flex while keeping mass efficient. The result is crisper steering response and more predictable handling during corner exits.

Fitment and Simple Installation

Designed to match Ultima SB geometry, this holder installs with basic hand tools and uses the existing mounting layout for a straightforward replacement. Quick to fit, it gets you back on track with minimal fuss.
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 UMW531B fit other Kyosho kits?

This part is made for the Ultima SB family and will fit those chassis without modification. Other Kyosho models may require adaptor parts or drilling to work.

What basic tools are needed for fitment?

A set of hex drivers and a small spanner are usually enough. Follow original screw torque and reuse existing hardware where possible.

How should I maintain the alloy holder?

Inspect mounting screws regularly, clean contact surfaces, and check for thread wear. The anodised finish helps resist wear but routine checks keep performance consistent.
