Overview
This is the Team Associated TC28 Gear Differential Set, a complete fluid-filled gear differential for the TC28 1/28 scale 4WD electric on-road touring car. The same assembly serves as either the front or the rear differential, so one part number covers both ends of the car.
The TC28 uses fluid-filled gear diffs front and rear with height and belt tension adjustment, and diff fluid is one of the most effective tuning levers on the platform. A second complete diff lets you keep a known setting ready instead of rebuilding between heats.
