GPM Racing Aluminium Centre 17 Piece RC Gearbox - GPM-TRX4038

The GPM Racing TRX4038 aluminium center gearbox is a 17-piece metal upgrade set designed as a direct replacement for the stock plastic center gearbox on the Traxxas TRX-4 trail crawler. The TRX-4's center gearbox takes significant load during crawling and trail driving, and this GPM Racing aluminium unit offers a more durable alternative for builders looking to move beyond the standard plastic housing. If you're running your TRX-4 on rocks, rough trails, or any demanding terrain, upgrading the center gearbox is a practical step in building a tougher drivetrain.
