Upper A-Arm Pins for Type-C Chassis - Yokomo YOKSD009U  [YOKSD009U]

Replacement Upper Arm Pins (Type-C)

This is a replacement RC part made to act as upper a-arm pivot pins for Type-C chassis. The pins act as the pivot mount, helping to lock the arm alignment under load and prevent lateral play that can disturb handling.

Fitting is straightforward for a hobbyist: extract the old pins, inspect the arm eyelets and any retainers for wear, then fit the new pins ensuring correct seating and retention. After installation, rotate the arm through its range to check for smooth travel and clearances.

In tuning scenarios, fresh upper a-arm pins contribute to repeatable suspension geometry and cleaner steering response on drift-focused setups. Use this part to remove pivot slop and keep alignment consistent while testing changes.
