Purpose-built replacement spur for Mugen Seiki MTX4 gearboxes, supplied as part MTX4-0860/V2 by 3Racing. The Delrin 60T 0.8 pitch design targets minimal rotational drag and repeatable tooth engagement for competitive on-road tuning.
Application brief: intended as a direct service item or tuning component for MTX4 platforms that require a 0.8 pitch 60-tooth spur. Confirm gearbox specifications before installation and match the pinion pitch and tooth count to retain optimal mesh and drivetrain reliability.
Installation and setup protocol: install on a clean spur hub, verify spline seating and axial runout, and set pinion backlash to the tight tolerance appropriate for your setup. While fitting, inspect bearings and drive alignment and use threadlocker only where specified by the chassis guidance.
Technical note: Delrin offers predictable wear and low friction under typical racing loads, helping preserve drivetrain response during tuning cycles and race day checks.
