The Kyosho UB013-02 Aluminum Rear Hub Mount replaces the fragile plastic stock part on the Ultima RB7.5, delivering improved strength and more repeatable suspension geometry. It is a practical upgrade for racers wanting consistent handling lap after lap.
Machined from quality aluminum, the UB013-02 increases resistance to wear and crash damage while helping the rear suspension retain accurate wheel alignment. That stability translates into more predictable behaviour during acceleration and braking.
This rear hub mount is aimed at drivers who push the Ultima RB7.5 at speed, providing a firmer mounting point that supports sharper turn-in and controlled exits without adding excess weight.
Installation is straightforward and uses the existing mounting points on the Ultima RB7.5 so you can swap the part quickly and get back on track with minimal setup time.
