Fine-Adjust Diff Preload Kit BD-508 for BD7/BD5

This Yokomo BD-508 kit provides a compact tension screw and matching spring for BD7 and BD5 scale RC differentials, enabling controlled changes to diff preload. It helps you dial in traction distribution and corner behaviour for competitive runs.

Installation is simple within compatible BD-series diff housings, and the kit allows incremental preload adjustment so you can tune spool-up and resistance without swapping the full diff assembly.

Will this kit fit aftermarket BD-series housings?

If the housing matches one of the Compatibility codes listed above, the BD-508 components will be compatible; verify the housing code before fitting.

How sensitive is preload change per screw turn?

Adjustments are sensitive; small turns produce noticeable preload shifts. Make gradual changes and compare lap times or handling feel to judge effect.

Does the kit alter internal diff gear spacing?

No, the kit changes preload via the tension screw and spring; it does not modify gear spacing or require gear replacement.
