MTX-4 Racing Intermediate Gear 23T Hardern Aluminium MTX4-0823 by 3Racing  [MTX4-0823]

Race-Oriented 23T Hardern Aluminium Gear for MTX-4

High-precision 23-tooth second gear engineered for the Mugen MTX-4 gearbox. CNC-style machining from Hardern aluminium delivers consistent tooth form for tuned spur and pinion combinations in competition or high-performance rebuilds.

Application and fit: the gear is built to match MTX-4 internal geometry and integrates with existing spur and pinion setups to alter final drive ratios in predictable increments. It is not a universal fit and should be used where MTX-4 specifications are met.

Service and setup: during installation check bearing radial play and shaft runout, establish optimal mesh with minimal backlash suitable for racing loads, and ensure pinion alignment under torque. Follow recommended torque values to preserve gearbox rigidity and tooth alignment.

Tuning impact: the 23T intermediate gear offers fine ratio steps for acceleration tuning without large jumps in top speed. Aluminium construction reduces rotating mass but requires careful thermal and wear monitoring in prolonged high-load sessions.
