The Kyosho UB013-02 Aluminum Rear Hub Mount is a solid upgrade over the stock plastic part on the Ultima RB7.5, adding toughness and consistent suspension geometry. It is a common choice for racers who need dependable rear mounting points.
This aluminum mount resists deformation and helps preserve precise wheel positioning, reducing unpredictable handling caused by worn plastic parts.
For drivers competing at club level or track days, the UB013-02 provides a firmer platform that supports crisp steering inputs and stable corner exits without compromising agility.
The part is designed to integrate with the existing Ultima RB7.5 setup, allowing a quick swap so you can spend more time running and less time fitting parts.
