The Kyosho UB005 is an aluminium front wheel shaft designed to bolt straight into the Ultima RB7.5 chassis, giving a sturdier connection at the front end. By replacing softer stock components, this shaft delivers more predictable steering and greater resistance to impact damage during club runs. It sits securely in the RB7.5 hub assembly to improve tracking and driver confidence on circuit surfaces.
Aluminium is favoured for being both light and durable, which helps reduce unwanted flex while keeping the car agile. Installing metal upgrades like the UB005 can lead to crisper steering feedback and easier corner-to-corner consistency. For hobbyists focused on lap time and longevity, the Kyosho UB005 brings practical gains without complex installation.
