The Kyosho UB035 Main Gear Shaft features the 8L/20T specification commonly used on the Ultima RB7.5. It serves as a straightforward swap-in part to maintain smooth gear engagement during track sessions.
Engineered for consistent tooth engagement, this shaft supports predictable drivetrain response for both practice and competition. Precision in manufacture helps reduce backlash and gear noise.
While optimised for the Ultima RB7.5, the UB035 may be used in other cars with matching gear profiles. Double-check shaft length and tooth count before attempting to fit it into a different chassis.
During installation of the Kyosho UB035 Main Gear Shaft, confirm alignment and run the drivetrain by hand to check for binding. Periodic checks and light lubrication of mating surfaces will keep things running smoothly.
