The Yokomo ZS-506A Differential Drive Ring set provides two drive rings intended for use during ball differential rebuilds. These components help restore precise engagement and keep drivetrain feedback predictable.
These rings are suitable for a number of Yokomo models, including DP-YD4, MRTC-86 and DP-GR35, making them handy spares for hobbyists with multiple cars. They simplify maintenance and help to standardise diff behaviour after servicing.
Produced to close tolerances, the drive rings give a reliable fit that limits excess movement and guards differential internals from unnecessary wear. They are well suited to both competitive use and everyday running where stable diff action is preferred.
