This aftermarket titanium main shaft is supplied as a 1pc economy replacement compatible with Kyosho Mini-Z AWD models. It is intended to replace worn shafts on MR-03 AWD layout cars without altering the surrounding geometry.
Fit and compatibility advice: confirm the MR-03 AWD layout and ensure sufficient axle clearance prior to installation. Preserve existing wave or flat washers and e-clips where they are the correct size for your model, and check spline seating in the gearbox output to eliminate lateral play. The shaft is suitable for those looking to improve wear performance over standard steel components.
Assembly notes: remove the old shaft and inspect bearings for wear, carefully slide the new shaft into the gearbox in the original orientation, and verify smooth free rotation before completing assembly. Do not trim or use shims unless the chassis manual authorises such changes.
