Compatible MTX-4 Delrin Spur Gear 0.8 Pitch 52T - MTX4-0852/V3 by 3Racing  [MTX4-0852/V3]

MTX-4 Compatible 52T Delrin Spur

This Delrin spur is made for use with Mugen Seiki MTX-4 gear trains and provides a 0.8 pitch, 52-tooth replacement designed for lower friction mesh options.

Delrin (acetal) commonly runs smoother against hardened pinions and holds its shape across normal RC operating ranges, offering a practical alternative to standard nylon spurs when tuning drivetrain feel and noise.

Fit the spur with attention to pinion alignment and recommended backlash for MTX-4 gearboxes, ensure the spur sits concentrically on the shaft, and confirm the gearset turns freely with your motor and pinion choice. Only use minimal gear lubricant if advised for your configuration and re-inspect the mesh after a short test session.
