Mugen Seiki MTX4 60T Delrin Spur 0.8 Pitch MTX4-0860/V2 by 3Racing  [MTX4-0860/V2]

60T Delrin spur designed for MTX4

This is a replacement spur gear for the Mugen Seiki MTX4 chassis supplied under 3Racing part number MTX4-0860/V2. The component is a 60-tooth unit at 0.8 pitch, molded in Delrin for reduced friction in 1/10 on-road drivetrains.

Compatibility and use: provided as a direct spare or upgrade piece for MTX4-series gearboxes that require a 0.8 pitch 60T spur. Always confirm your chassis and gearbox specification and ensure the pinion gear matches the pitch to maintain correct mesh.

Fitting advice: fit the spur to a clean hub, check for axial runout and secure spline engagement, and verify pinion mesh to avoid backlash or binding. Inspect bearings and axle alignment while the gearbox is open and use threadlocking only where the manufacturer recommends it.

Tuning role: as a Delrin spur the part aims to minimise rotational drag and maintain consistent tooth engagement under typical running loads, making it suitable for service replacement or drivetrain checks during setup adjustments.
