Precision Front Bulk Head for Ultima RB7 Chassis

The Kyosho UM703B Front Bulk Head fits the Ultima RB7 and tightens the front assembly to improve steering predictability. Built from quality components to resist race day wear, it serves as both a replacement and an upgrade for serious setups.
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 Kyosho UM703B a direct swap for the factory part?

Yes, it is intended as a direct replacement for the stock front bulk head on the Ultima RB7, aligning with the original mounting points and geometry.

How should I check alignment after fitting the unit?

After installation, confirm steering linkage and kingpin alignment, then run a few slow laps to verify neutral steering and consistent toe settings.

Does this part need periodic maintenance?

Inspect mounting screws and bearing seats periodically and replace any degraded hardware to keep the front end precise and free of play.

Will changing the bulk head affect suspension setup?

Because the unit preserves original geometry while improving stiffness, suspension balance is usually retained, though minor trim to camber or toe may be useful when fine tuning.
