TRAXXAS Latrax Rally / Sst / Teton Steel-Aluminium Ball Differential by GPM LTX100S  [LTX100S]

Ball differential for Latrax series

This is an RC-scale ball differential designed by GPM for Traxxas Latrax platforms, intended as a replacement or upgrade part for hobby models. The unit combines metal and engineered-plastic components to manage drive torque transfer between wheels and to allow tunable diff action for handling balance.

Key components listed by the manufacturer include ball bearings, thrust washers, a Delrin pulley, and aluminium output cups. The design uses the ball differential mechanism to deliver adjustable resistance, which is changed by tightening or loosening the central adjustment screw to vary how freely the axle halves rotate relative to each other.

In practical terms for RC use, this part is aimed at hobbyists who need a compact, serviceable diff that fits Latrax-scale drivetrains and who want the ability to fine-tune torque distribution for cornering behaviour. It is an accessory part for electric RC models and not for full-size vehicles.

Use this GPM ball differential when replacing a worn diff or when adding a tunable unit to Latrax-series models; check fitment against your chassis before installation and retain original mounting hardware when possible.
