This Metal Diff Set is a pre-assembled differential designed for ARRMA RC models. It features a 37-tooth, 1.35 module gear set and is ready to drop into the front or rear of a model, delivering durability and precise gear mesh.

The assembly uses a steel 1.35 module main gear for strength, precision-manufactured gears for accurate tooth mesh, a tough composite diff case to keep everything aligned, and high-strength steel internal gears with splined output shafts. It arrives pre-assembled and filled with 10,000 cSt silicone oil for smooth, reliable operation.
