Tamiya CC02 Aluminum Center Gearbox Upgrade CC2038 by GPM  [CC2038]

6061-T6 center gearbox for CC02 trail rigs

This aftermarket center gearbox is a scale RC accessory crafted for the Tamiya CC02 MERCEDES-BENZ G500 platform. Machined from 6061-T6 aluminum, it helps stabilise the transmission gears inside the CC02 center assembly and supports a more consistent steering feel and drivetrain stability under crawling loads. The component is a hobby-grade RC part and is not for real vehicle use.

The part replaces the original plastic center gearbox to provide a firmer mounting surface for internal gears and to improve dimensional accuracy where the gearbox meets driveshafts and bearings. Because aluminum moves heat away from gear interfaces faster than plastic, the material can assist with heat dissipation during long trail sessions, which can help maintain run-to-run consistency.

Installation notes: fitting this upgrade requires access to the CC02 center transmission area and basic disassembly of the center assembly. Verify gear mesh and bearing alignment when reassembling to maintain smooth rotation and correct steering response. Check screw torque and gear engagement after first runs for reliable performance.

This CNC-machined center gearbox suits hobbyists refining CC02 drivetrains who want a stiffer gearbox mounting and improved thermal behaviour compared with the stock plastic housing.
