Axial EXO Steel Center Swing Shaft Upgrade EX037S by GPM  [EX037S]

Center Swing Shaft for EXO Chassis

The EX037S steel center swing shaft is an aftermarket replacement made for use with the Axial EXO chassis and supplied as a single set. As a direct swap for the central swing assembly, this steel shaft is intended to increase center drivetrain stability and provide better wear resistance than common stock materials.

For builders tuning drivetrain feel, a steel center swing shaft changes feedback and stiffness around the center diff and linkage. Expect a firmer connection through the center drivetrain that can reduce flex under heavy loads during aggressive trail runs or bashing, while also transferring more shock to adjacent linkages and mounting points.

Installation is straightforward for those familiar with EXO center assemblies: remove the original shaft from the center swing carrier, inspect bearings and linkage pins for wear, install the steel shaft in the same location, and confirm free movement of the swing arms before reassembly. Do not overtighten fasteners and verify that nearby ball bearings rotate freely after installation.

Maintenance advice: inspect the shaft and bearing mating surfaces periodically for wear and corrosion, use appropriate lubrication for steel-to-bearing contact, and replace worn link pins or bearings to avoid premature wear on the shaft.
