TT-02BR Balldiff Gearbox Joints, RC spare parts

TT-02BR Balldiff Gearbox Joints are a focused RC spare parts set for maintenance on the TT-02BR platform. The pack centers on 2 molded joint pieces paired with 2 retaining rings and 2 metal pins, a combination suited to rebuilding a worn or incomplete balldiff gearbox connection with the correct matching hardware. The black joint components use a cylindrical upper section and a slotted lower end, a shape that indicates a guided mechanical fit where the pin locks the part in place and the retaining ring secures the assembly. That layout matters during service work because small drivetrain parts need the right companion pieces to go back together cleanly. Instead of mixing general workshop hardware, this set keeps the parts grouped for the specific TT-02BR balldiff area. The compact format also makes it practical to keep as a bench spare for routine rebuilds. Used during repair or scheduled maintenance, the set supports a direct refresh of the gearbox joint area when wear, loss or disassembly interrupts a running chassis. On a hobby bench, the separated parts are easy to identify before installation, and the matched count of joints, rings and pins helps keep the rebuild process organized.
