Stronger Rear Bulk Head for RB6

The Kyosho UM724B rear bulk head is engineered for RB6 chassis with mid-motor configuration to add stiffness and keep drivetrain parts aligned during aggressive running. It is built to stand up to frequent track sessions without degrading handling.

Why Fit the UM724B

Fitting the UM724B helps centralise mass and reduce unwanted flex, improving predictability through corners. It is an effective replacement for worn components and a helpful tweak for drivers chasing consistent lap times.
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 UM724B bolt-on or does it require modifications?

Installation is generally bolt-on to RB6 mid-motor mounts, but verify screw types and torque settings to avoid misalignment. No major chassis surgery is normally needed.

Will this affect battery placement?

The UM724B itself does not change battery tray location, but improved rigidity can make weight distribution adjustments more noticeable when you relocate batteries for tuning.

Can I use standard RB6 screws with this part?

Most standard RB6 mounting screws will fit, though using fresh hardware and thread lock where appropriate helps keep a secure connection during hard running.
