AXIAL SCX10 Adjustable Main Shaft SCX037SAN Upgrade by GPM  [SCX037SAN]

Tunable main shaft for SCX10 crawlers

This aftermarket main shaft assembly is specified for AXIAL SCX10 platforms and pairs aluminum 6061 T6 housings with hardened steel #45 adjustable swing shafts and a cross-head universal joint. The set preserves scale fit while improving articulation and weight distribution for crawling and trail driving.

The alloy shaft body reduces rotating mass versus fully steel constructions, and the hardened adjustable shafts deliver the torsional strength required for steering and axle movement. The cross-head universal increases the steering arc available, which helps on steep approach angles and tight crawling lines without modifying chassis geometry.

Fitting is the same as other SCX10 driveline swaps: remove original main shafts, install alloy housings, adjust shaft lengths, and secure with the supplied hardware. After fitting, verify steering link geometry and driveline clearance across full suspension travel before final tightening.

This shaft kit suits builders wanting a lighter alloy housing married to hardened adjustable shafts to fine tune steering angle and driveline behaviour on AXIAL SCX10 1/10 scale electric 4WD models.
