The GPM Graphite Main Shaft, model GXM025/2WD, is produced as a direct-fit replacement for XMODS Radio Shack platforms. Using a consistent graphite compound, the shaft reduces rotating mass and maintains torsional stiffness to support improved handling and reduced wear on mating parts.
GPM parts are intended to provide reliable upgrades that fit without extensive modification. The Graphite Main Shaft GXM025/2WD is recommended for model owners focused on a measurable reduction in rotating mass and consistent long term performance.
