Compared to the conventional upper arm, this version is approximately 6mm shorter in overall length, making it possible to achieve narrow rear A-arm setups that were previously limited by design constraints. (Note 1)
It can also be used as a front upper arm. (Note 2)
Notes: 1) For narrow setups, we recommend using the simultaneously released PM Upper Arm Shaft 23.5mm (R31S117). 2) If you are using a turnbuckle-type upper arm, please prepare a D-cut type PM Upper Arm Shaft (R31S001 / R31S012 / R31S063) along with M3×4mm set screws, sold separately.
