The Kyosho UB035 Main Gear Shaft uses an 8L/20T configuration and serves as a practical replacement for the Ultima RB7.5 drivetrain. Its consistent manufacturing tolerances support steady gear engagement under typical club and track use.
This shaft is aimed at RC users who value steady drivetrain behaviour. The accurate tooth form and shaft dimensions help the Ultima RB7.5 maintain predictable power transfer and reduced slop.
Designed primarily for the Ultima RB7.5, the UB035 may be suitable for other cars with the same 8L/20T specs. Always measure and compare key dimensions if fitting to alternate models.
Ensure the Kyosho UB035 Main Gear Shaft is seated and aligned correctly during installation. Regular checks of mesh and bearings will prolong the life of the gear train.
