ARRMA Diff Case 49T Main Gear/17T Input Gear RC Differential - ARAC4025

The ARRMA AR310802 differential case assembly (style code ARAC4025) is a genuine ARRMA spare part housing a 49-tooth main gear and 17-tooth input gear, designed to restore or replace a worn or damaged diff unit in compatible ARRMA vehicles. This RC differential is a direct factory-spec component, meaning it matches the original gear ratios and fitment without modification.
