Part #: 231410-R
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. These arms have double shear sway bar mount tabs with endlink set included as well as a double shear shock mount to fit most 1/2" bolt race shocks. Lower arms are compatible with UMI/Strano, Viking, Penske, JRi, and most other race shocks. Upper arms feature caster and camber adjustment with premium rod ends. Laser cut ball joint pads feature improved ball joint angle and increased caster (up to additional 2 degrees - depending on chassis tolerances) for lowered cars and come assembled with premium ball joints. UMI's newest design features the most travel and clearance of any a-arm on the market and is a must for lowered vehicles. This A-arm kit 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.
