This GPM replacement kit provides front constant velocity drives and rear axle shafts specified for TRX4M Ford Bronco 1/18 scale kits. Components are produced from medium carbon steel and are engineered to restore drivetrain geometry while offering reliable service life under typical crawling and trail loads.
The components focus on accurate transmission of wheel rotation through the front CVD area and rear axle assemblies, supplying a direct-fit replacement for worn or damaged stock items. Packaged as a complete kit, the parts reduce workshop downtime by avoiding the need for additional machining in compatible TRX4M configurations.
Fitment and inspection: removal of front and rear driveline housings is required. Use standard RC tools for disassembly, verify spline engagement and bearing interfaces during installation, and perform a slow hand rotation to confirm smooth operation and correct alignment before running the vehicle.
Application guidance: these medium carbon steel shafts deliver dimensional stability under load, making them suitable when replacing fatigued OEM components or preparing a TRX4M rig for frequent trail use where metal drive parts are preferred.
