Kyosho Mini-Z AWD Compatible Titanium Main Shaft TMZA025E by GPM  [TMZA025E]

Lightweight replacement shaft for Mini-Z AWD

This single-piece titanium main shaft is provided as an economy replacement compatible with Kyosho Mini-Z AWD models. It serves as a direct swap to renew an MR-03 AWD style drivetrain while keeping original geometry intact.

Fitment tips: check that your car uses the MR-03 AWD layout and confirm axle clearance before fitting. Keep original wave or flat washers and e-clips that match your unit, and ensure the spline meshes cleanly with the gearbox output to prevent drive train play. This shaft can form part of a wear-focused tuning program compared to standard steel parts.

Fitting advice: remove the old shaft, inspect bearings and seals for wear, slide the new shaft into the gearbox in the same orientation, and check for smooth rotation prior to reassembling. Do not trim or add shims unless stated by the chassis manual.
