Improve RB6 Chassis Stability with the UM724B

The Kyosho UM724B rear bulk head is intended for the RB6 with a mid-motor arrangement, reinforcing the rear end and delivering accurate mount points for suspension and driveline components. It is designed to resist track wear and keep geometry stable under load.

Performance Benefits of the UM724B

By increasing rear-end stiffness the UM724B aids weight transfer control and can sharpen handling response. It serves well as a replacement for fatigued parts or as part of a handling upgrade package for racers seeking repeatable setup behaviour.
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 fitting this change my handling drastically?

Expect firmer rear-end behaviour and slightly crisper turn-in. Changes are subtle but improve consistency, especially if you previously had a worn bulk head.

Are aftermarket upgrades compatible with the UM724B?

Most RB6-compatible aftermarket components will work with the UM724B, but always check mounting clearances and link lengths before fitting to avoid interference.

How often should I inspect the bulk head?

Inspect after heavy impacts or every few race meetings; look for hairline cracks, elongation of screw holes and loosened fasteners, and replace if any fatigue is visible.

Can this part be used for practice and race days?

Yes, it is suitable for regular practice and race use. Its construction is aimed at enduring repeated sessions while maintaining alignment and handling characteristics.

Do I need special screws or washers?

Standard RB6 mounting hardware will usually suffice, though replacing old screws and using small washers can help distribute load and prevent wear at mounting points.
