This RC-scale hinge pin set is built for the DP-DPR Upper A arm used on Yokomo drift packages. The components provide exact replacement pivot points at the upper A arm mount, restoring a secure connection and repeatable geometry while leaving the chassis layout unchanged.
Compatibility is restricted to the DP-DPR Upper A arm mounting locations specified; do not attempt to fit them to unrelated mounts. Fitting is simple on stock assemblies: remove worn pins, align the upper arm, then refit the replacement pins in the original sequence. After installation, check for smooth travel and absence of lateral play.
As part of setup and tuning, these hinge pins function as maintenance parts that preserve factory geometry. Exchange pins during regular servicing to sustain consistent steering feel and reliable weight transfer in drifting. Always verify upper arm alignment and pivot clearances against your baseline measurements after service.
