Upgrade the differential on your Yokomo with the B2-508TSA Locking T-nut and Thrust Spring Set, made for YZ-2, YZ-4, and MAX2 cars. The set helps you dial in consistent diff behaviour while resisting wear from frequent running.
The B2-508TSA supplies a locking T-nut and a matched thrust spring to secure the diff internals. With a firmer hold on the assembly, you will notice reduced play and steadier power transfer through corners.
Intended for straightforward installation on Yokomo YZ-2, YZ-4, and MAX2 models, this hardware is handy for drivers who switch between carpet, asphalt, or loose surfaces and want predictable diff response.
