Yokomo YZ-009IW1 inner suspension arm pin for Works'91 TeamSpec, inner arm pin for YZ-W91TS/YZ-W91  [YZ-009IW1]

Inner suspension arm pin

This RC-scale inner suspension arm pin is designed to restore or modify the inner pivot on Works'91 TeamSpec style chassis, supplied as a set of 2pcs. The part increases the overall length at the inner arm pivot to provide a mounting point for a torque rod without altering the outer arm geometry.

Fit and installation are straightforward when working within the YZ-W91 platform layout, the pin replaces the factory inner pivot location and accepts the chassis' existing attachment path for a torque rod. Check alignment with the inner arm and torque rod to ensure smooth movement through the suspension travel.

In tuning, this pin serves as a simple hardware option to add or test torque rod mounting points on the inner arm, enabling incremental changes to roll and traction behaviour on track setups while keeping other suspension dimensions unchanged.
