The Yokomo ZD-506 Drive Ring is a simple replacement part that helps preserve differential efficiency in on-road RC cars. These rings are made for routine service and help sustain reliable torque transfer during both club races and weekend practice sessions.
These drive rings suit many 1/10 scale on-road models and are a practical spare for hobbyists who perform regular maintenance. Swapping worn rings prevents extra stress on gears and bearings and keeps your drivetrain behaving predictably.
Before installation, clean the differential housing and remove grime to ensure a snug fit. Check the rings periodically for flat spots or wear and replace them as needed to avoid secondary damage to gears.
