TRAXXAS E-Revo and Summit Adjustable Steel Drive Shafts ER037SF+AR by GPM  [ER037SF+AR]

Overview of the shaft set

The ER037SF+AR set supplies matched front and rear drive shafts made for 1/10 TRAXXAS E-Revo and Summit hobby models. Main shaft material is Steel #45 and the package includes a small aluminium collar plus the pin hardware required to hold the assembly together. The design allows the effective shaft length to be tuned between 75mm and 80mm for common axle arrangements.

These components are intended as replacement or tuning parts for RC drivetrains. Steel #45 offers a predictable hardness range among common hobby steels, helping manage wear at pin joints while remaining within model-scale use. Steel retaining rings are fitted at both ends to help retain the supplied screw pins during running and servicing.

The source lists included items exactly as follows: 6x8x5 aluminium collar, quantity 1 pc; and 2.5xM4Tx15 screw pins, quantity 2 pcs. No additional hardware or tools are claimed, so installers should use typical model tools and any extra fasteners as required.

For model builders who prefer steel shafts with a short adjustable range, the ER037SF+AR offers a direct parts-level option for TRAXXAS E-Revo and Summit drivetrains using Steel #45 and the listed small securing hardware.
