Stiffen the Rear End on Your Ultima SB with Kyosho UMW531B

The Kyosho UMW531B Aluminum Rear Suspension Holder replaces soft plastic mounts with a precision-machined aluminium unit for the Ultima SB series. Its accurate dimensions give a secure fit that helps reduce play and improves consistency lap after lap.

Why Choose This Rear Holder

This alloy holder reduces unwanted chassis flex while keeping weight efficient, delivering a firmer rear feel that benefits cornering balance and throttle control. It is aimed at drivers wanting a direct handling response.

Compatibility and How to Fit

Built to suit the Ultima SB chassis layout, the UMW531B is a direct-fit replacement in most cases. Installation is straightforward using common hex tools and the original mounting hardware.
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.

Is the alloy holder significantly heavier than the plastic part?

The aluminium piece can be slightly heavier than stock plastic, but it reduces flex and improves handling trade offs that many drivers prefer.

How long does installation usually take?

A typical swap takes 15 to 30 minutes for someone familiar with basic RC maintenance. Take care to align parts before tightening fasteners.

Can I use this with aftermarket suspension arms?

Compatibility depends on the arm geometry. Many aftermarket arms that follow Ultima SB dimensions will work, but check measurements to avoid clearance issues.
