The Kyosho UB005 is an aluminium front wheel shaft that replaces the stock item on the Ultima RB7.5 to give a stronger, more precise front end. Its metal construction reduces wear and improves steering feel, which is useful for drivers tuning setups or competing in time attack sessions. The UB005 fits the RB7.5 layout and helps maintain consistent handling under race conditions.
Aluminium combines lightweight properties with durability, making it ideal for critical suspension and steering parts. Replacing plastic shafts with the UB005 can yield sharper steering inputs and lower long-term maintenance. For enthusiasts aiming for predictability and reduced component fatigue, the Kyosho UB005 is a practical component upgrade.
