Axial EXO Centre Diff Input Shaft Upgrade Steel - EX041S by GPM  [EX041S]

Robust steel centre diff input shaft

This is an RC-scale centre differential input shaft intended for compatibility with the Axial Racing EXO drivetrain, identified as model EX041S. Constructed from steel and supplied as 1pr, it replaces the stock input shaft to increase service life and resilience under normal running conditions.

Installation involves removing centre drivetrain components, aligning splines and bearings, and confirming correct gear mesh; check fit before final assembly and use recommended thread locking compounds where applicable. This shaft is a direct drivetrain replacement for scale RC models only.

The shaft helps maintain steady torque transfer through the centre differential and is a common choice when tuning for stronger drivetrain performance or when carrying out scheduled maintenance replacements.
