Team Associated ASC31782 TC7.2 Gear Diff Rebuild Kit

The gear differential is a maintenance item on any competition touring car. Diff oil breaks down, seals take a set, and washers wear, and once the diff starts to leak or feel notchy, the car loses drive consistency and corner exit traction. This rebuild kit gives you the seals and hardware to service it properly instead of chasing handling problems with setup changes.

The kit includes one gear diff case O-ring, four diff T-nut washers, two 5 x 12 x 0.2 mm shims, and four 4.9 x 1.9 mm O-rings. It is designed for the Team Associated TC7.2 gear differential and is also used with the #92076 gear diff plastic gears, so it covers a full seal and shim refresh in one package.

Rebuilding your diff with fresh seals restores a leak-free case, correct internal preload, and the smooth, consistent action that makes diff oil changes an actual tuning tool. Most racers keep a couple of these kits on hand so a diff service never has to wait for a parts order.
