YZ-W91TS / YZ-W91 Inner Arm Pin, compatible with Works'91 TeamSpec - Yokomo YZ-009IW1  [YZ-009IW1]

Inner arm pivot details

This inner suspension arm pin for RC models is built to modify or replace the inner pivot on Works'91 TeamSpec format chassis and is supplied as two pieces. Increasing the pivot length allows a torque rod to be mounted while leaving outer arm geometry intact.

Installation on YZ-W91 layout types is typically direct: the pin takes the place of the stock inner pivot and accepts the existing torque rod routing on the chassis. Ensure the inner arm and torque rod line up correctly so movement through suspension travel is unhindered.

Use this pin as a tuning aid to test torque rod placements on the inner arm, enabling measured adjustments to roll balance and traction without changing other suspension parameters.
