SCX27038MG is a single-piece steel middle gear manufactured for AXIAL-compatible transmissions and intended as an aftermarket upgrade. The design focuses on accurate shaft engagement and bearing mounting to maintain drivetrain geometry under load.
The gear ships with two 5x10x4 bearings to support correct axial location and rotational support. During installation verify bearing preload and gear mesh, and follow standard gearbox assembly practice to ensure consistent drivetrain performance.
