The Kyosho UB017 main chassis uses premium 7075 aluminium to strengthen the Ultima RB7.5 platform. It is engineered to stand up to regular competitive use while keeping mass distribution favourable for handling adjustments. Designed specifically for Ultima RB7.5 owners, it provides a solid foundation for setup work.
Constructed from 7075 aluminium, the UB017 delivers reliable rigidity without unnecessary weight. Precision machining ensures mounting points line up cleanly, so installation is straightforward and your components sit squarely. That predictability helps when dialling in suspension settings.
By reducing chassis twist, the Kyosho UB017 improves traction and steering feedback, making the car more responsive through corners. The added stiffness aids consistent lap times across varying track surfaces.
