This RC-scale hinge pin set is intended for the DP-DPR Upper A arm on Yokomo drift packages. These parts act as direct replacement pivot points where the upper A arm rotates on the suspension assembly, reestablishing a secure connection and repeatable geometry without modifying the chassis layout.
Fitment is confined to the DP-DPR Upper A arm mounting points as specified, so do not attempt to adapt them to other components. Installation on stock setups is straightforward: remove the worn pins, position the upper arm, and fit the replacements following the original hardware sequence. Confirm free suspension movement and check for any side-to-side play after refit.
For setup and tuning, fresh hinge pins maintain the intended suspension geometry. Replace them during routine servicing to retain consistent steering response and dependable weight transfer during drift sessions. After changing pins, verify upper arm orientation and pivot clearances against your setup notes to preserve handling characteristics.
