Traxxas Latrax Ball Differential SST100S by GPM  [SST100S]

Precision engineered steel and aluminium ball diff

This aftermarket ball differential is engineered as a serviceable replacement for Traxxas Latrax platforms. The unit uses hardened steel running elements together with aluminium output cups and precision ball hardware to deliver a predictable, adjustable torque transfer for Latrax Rally, Latrax Stadium Super Truck (SST) and Teton vehicles.

Internally the assembly features ball bearings, thrust washers, a delrin pulley and aluminium output cups configured to allow preload adjustment via the central screw. Altering the central screw changes the preload on the ball stack and thereby modifies slip characteristics and turn-in response without requiring changes to other drivetrain components.

Designed for hobbyists who prefer to service and tune their drivetrain, the diff is straightforward to disassemble with standard hex drivers and basic workshop tools. Regular inspection of the balls and washers and re-lubrication with a light differential grease will help maintain consistent adjustment and long-term reliability.

For best results inspect bearing surfaces during scheduled maintenance, replace any worn thrust washers or balls, and use minimal grease when rebuilding to preserve precise adjustment feel.
