Mini-Z MR-03 AWD Titanium Main Shaft TMZA025E by GPM  [TMZA025E]

Titanium main shaft upgrade for Mini-Z MR-03 AWD

This titanium main shaft is supplied as a single-piece economy option compatible with Kyosho Mini-Z AWD platforms. It is intended as a direct replacement to refresh MR-03 AWD drivetrain components without altering surrounding geometry.

Compatibility and fitment guidance: verify MR-03 AWD gearbox layout and axle clearance before fitting, retain your existing wave or flat washers and e-clips where they match your model, and inspect spline engagement at the gearbox output to avoid endplay. Use this shaft when tuning for improved wear resistance versus standard steel shafts.

Installation notes: remove the worn shaft and check associated bearings for signs of wear, insert the replacement in the same orientation as the original, and confirm free rotation before final assembly. Avoid trimming or adding shims unless your chassis manual explicitly permits them.
