Chamfered F_ Upper I_arm Purple for RD/SD/MD

This is an aluminum I-arm for use on the front upper arms. It features a red anodized finish to match the red version of the YD-2 series. The caster angle can be adjusted by 7mm forward and backward using the spacer, allowing for a wider adjustment range and a smaller caster angle than the standard. Despite being made of highly rigid aluminum, the I-arm design keeps it as lightweight as possible. When changing from the standard resin arm to this product, please use the upper I-arm rod end adapter in conjunction with this product.
