Design intent and fitment

This 1pc aftermarket main shaft is intended for scale RC drivetrain installations on Tamiya M1025 Hummer rigs and DF01-based setups, delivering a direct connection to the wheels for improved throttle feel.

The core shaft is produced from 6061-T6 aluminium to balance lightness and strength, while the contact points use hardened steel fittings to secure the gearbox output and wheel hubs with minimal added mass.

An anodized finish reduces surface abrasion and helps preserve accurate alignment through repeated use in hobby conditions.

Included hardware: Red Ring 3*1.5 - 4 pcs, E-Clip 4mm - 2 pcs. Supplied as a single-piece replacement intended for compatible tractors and crawler conversions.

Do I need extra shims or spacers to install this?

Most installs use the provided rings and E-clips, but check hub clearance and gear mesh on your chassis; small spacers or shims may be needed in some DF01 conversions.

Is the finish durable for outdoor running?

The anodized surface helps resist everyday scratches and wear, but avoid prolonged exposure to corrosive conditions and rinse off mud and salt after running.

Will this change gearing or clearance?

The shaft keeps original interface dimensions; it is intended as a like-for-like replacement, though you should confirm clearance and gear engagement on your particular build.
