TRAXXAS E-Revo/Summit Aftermarket Steel Drive Shafts ER037SF+AR by GPM  [ER037SF+AR]

Overview and intended use

The ER037SF+AR drive shaft set supplies a matched pair of front and rear shafts for 1/10 TRAXXAS E-Revo and Summit models, supplied for hobby use. The shafts are made from Steel #45 for the main sections and the kit includes a small aluminium collar plus pin hardware to secure the assembly. The effective shaft length can be adjusted between 75mm and 80mm to fit common drivetrain geometries.

This kit is aimed at replacement and tuning duties on RC drivetrains. Steel #45 is chosen for predictable hardness within hobby steel grades, offering useful wear characteristics around pin joints without implying suitability beyond model-scale applications. Steel retaining rings at both ends assist in keeping the supplied screw pins in position during running and maintenance.

Included items are stated exactly as in the source: 6x8x5 aluminium collar, quantity 1 pc; and 2.5xM4Tx15 screw pins, quantity 2 pcs. No further hardware or installation tools are listed, so fit using standard modelling tools and add size-appropriate fasteners if needed.

If you run a TRAXXAS E-Revo or Summit and prefer steel shaft components with an adjustable span, the ER037SF+AR offers a direct parts-level option using Steel #45 and the basic securing hardware shown above.
