TRAXXAS LATRAX SST Steel+Aluminium Ball Differential by GPM SST100S  [SST100S]

Steel & Aluminium ball differential

This GPM ball differential is an RC-scale replacement part built for TRAXXAS LATRAX platforms. The unit combines steel and aluminium components with precision ball elements to form the internal running surfaces, and it is intended for Latrax Rally, Latrax Stadium Super Truck (SST) and Teton model use.

Internal hardware includes ball bearings, thrust washers, a delrin pulley and aluminium output cups, assembled to allow a user-adjustable torque feel. Adjustment is done via the central screw, which changes the pre-load on the ball stack to alter slip and turn-in behavior without modifying other drivetrain parts.

Use this unit when you want a serviceable aftermarket diff that fits the referenced Latrax models, provides a predictable adjustment range, and is straightforward to service with basic RC tools such as a hex driver and clean workspace for the small components.

For maintenance, inspect the ball bearings and washers for wear during routine servo and motor service intervals, and reassemble with light grease appropriate for ball differentials to retain smooth adjustment action.
