MTX4 0.8 Pitch Delrin Spur 54T MTX4-0854/V2 by 3Racing  [MTX4-0854/V2]

Delrin Spur for MTX4

The MTX4-0854/V2 is a 54-tooth Delrin spur gear manufactured for replacement use in Mugen Seiki MTX4 assemblies. Version 2 matches the standard 0.8 pitch specification used on MTX4 spur systems and is offered as a spare or upgrade option.

Fitment and role: designed to substitute the factory spur in the MTX4 gearbox, the Delrin tooth profile aims to reduce meshing drag where compatible. Before fitting, verify your pinion and gearbox spacing on the specific MTX4 build to avoid incorrect engagement.

Installation notes: remove the gearbox cover, preserve any original shims and spacers, fit the 54T Delrin spur on the same hub, and manually rotate the drivetrain to check axial runout and mesh before sealing the case. Confirm backlash across steering and suspension travel with the original pinion.

Tuning considerations: because Delrin has lower surface friction than some other plastics, the drivetrain response may change slightly. After swapping, check slipper or clutch settings and drivetrain lubrication to maintain consistent behaviour on track or trail runs.
