MTX-4 Low-Drag Delrin Spur Gear 53T 0.8 Pitch MTX4-0853/V3 by 3Racing  [MTX4-0853/V3]

Low-Drag Delrin Spur for MTX-4 Chassis

Designed for the Mugen Seiki MTX-4, this replacement spur carries the 3Racing part number MTX4-0853/V3. The Delrin construction and 0.8 pitch 53-tooth specification in Version 3 help reduce friction where the gears mesh.

For correct fitment on MTX-4 gearboxes, ensure the spur sits flush, check centre distance against the gearbox layout, set the motor pinion mesh precisely, and confirm smooth rotation by hand before final assembly. It is intended as a direct replacement or maintenance spare for matching pitch and tooth count systems.

When tuning, the reduced friction of a Delrin spur helps lower drivetrain resistance and can make throttle transitions smoother under light load. Monitor wear and verify mesh clearance and bearing condition to keep the drivetrain reliable.
