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

Performance-Focused MTX4 Spur

The MTX4-0854/V2 is a Version 2 54-tooth Delrin spur gear optimised for MTX4 transmissions where lowered meshing friction is desired. Manufactured to meet 0.8 pitch dimensional standards, it is intended for use as a direct replacement or dedicated race spare.

Fitment and role: designed for MTX4-style gearboxes, this spur reduces contact drag in the drivetrain and can contribute to more consistent power delivery in tuned setups. Ensure pinion pitch and centre distance match the MTX4 specification prior to installation.

Installation notes: remove the gearbox cover, retain original shims and spacers, mount the 54T Delrin spur on the factory hub, and inspect axial runout and tooth engagement under slow rotation before reassembly. Use the original pinion or a correct 0.8 pitch racing pinion and confirm backlash through full suspension articulation.

Tuning considerations: Delrin's lower surface friction affects drivetrain damping and slip behaviour; after fitting, re-evaluate slipper or clutch preload, check for consistent mesh under load, and consider light, targeted lubrication on non-mating surfaces to control wear without increasing drag.
