UMI’s heavy duty boxed arm kit with adjustable rod ends provides a rock-solid foundation for your autocross, road race or corner carving 4th Gen. The lower a-arms fully gusseted box tubing construction, while appearing heavy-duty, affords a five pound weight savings per set over factory lower a-arms.

This A-arm kit is designed to work with the factory K-member, UMI k-members, and virtually all stock mounting point aftermarket K-members. Crafted with pride in Philipsburg, PA- USA.
