The Kyosho UB013 aluminum rear hub carrier is crafted to fit the Ultima RB7.5 range with tight tolerances. Its machined construction gives racers a dependable replacement for standard components while keeping fitment straightforward.
Made from quality aluminum, the UB013 increases rigidity over stock plastic carriers which helps maintain consistent wheel alignment under load. That translates to steadier handling and a predictable rear end during fast lap work.
This hub carrier is built specifically for the Ultima RB7.5 to ensure correct geometry and simple installation. Basic RC tools like hex drivers will get you fitted quickly with minimal adjustment needed.
Aluminum upgrades are popular because they combine light weight with higher fatigue resistance. Swapping to the UB013 lets drivers gain a tougher rear assembly without compromising overall balance.
