## Description

Product Type: This RC car part is a 39 tooth differential gear assembly designed for hobby grade RC car, built as a compact round gear and cup unit with a precision machined metal structure.
Function: As a differential gear, it helps transfer drive power transfer the drivetrain while supporting smooth gear action with the included main circular component gear, bevel gears, shafts, and bearings.
Construction: The aluminum differential housing and powder metallurgy gear are paired with shims, screws, washers, and a clear circular circular component for a complete steel gear assembly set build.
Nice fit: The precision machined components are made to work together in a tight, organized assembly, helping maintain stable alignment within the differential case.
Purpose: This 39 tooth differential gear assembly is intended to replace or assemble a drivetrain component for RC car use, supporting consistent mechanical performance in the drive unit area.

This RC car part is a 39 tooth differential gear assembly intended for hobby grade RC car, combining a compact round gear and cup layout with precision machined metal components. It brings together the main circular component gear, differential case, bevel gears, shafts, shims, screws, washers, a clear circular circular component, and bearings in one organized assembly. Built around an aluminum differential housing and a powder metallurgy gear, the steel gear assembly set is designed as a sturdy drivetrain component with a tightly snug construction. The included parts work together to form the differential mechanism, helping the gear assembly operate as a coordinated unit rather than a loose collection of pieces. Because the components are machined metal parts, the assembly presents a clean, exact alignment that suits detailed RC maintenance or replacement work. It is intended for users who need a differential gear solution that matches the mechanical demands of model car drivetrain and keeps the drive unit area running with a properly assembled internal structure.

Option: Red 1PC Diff Case
