The Samix Traxxas TRX-4 Brass Differential Case is a direct fit upgrade for the stock plastic TRX-4 diff cup. This machined brass upgrade is stronger than the stock parts and will help to create a longer lasting differential. Plus the cup weighs 17 grams, so it helps to add weight down low and lower the overall center of gravity. Package includes one brass diff cup.

Does not fit with stock trx4 parts. The mesh is too small. Tried 2 of them.

Upon receiving this part I began to fit it only to realise that it has been machined wrong and the diff locking spool does not fit into the teeth in the samix diff case yet I have x3 hot racing ones and x4 yeah racing ones and it fits on all those perfectly plus the standard traxxas diff case ??

Had no issue with the teeth meshing correctly. The machine work appeared to be quality. There were no burrs and all surfaces were finished smoothly. Quality part for the front or rear diff.
