Starting at $499.99/set

Our heavy duty boxed lower a-arms for 1993-2002 GM F-body cars are designed to be a direct factory replacement bolt-in as an alternative to our wildly popular tubular lower a-arms. Our P/N 2309 (Rod ends) and P/N 2312 (Roto-Joints) provides a rock-solid foundation for your autocross, road race or other heavy duty suspension needs. The a-arms fully gusseted box tubing construction, while able to handle virtually any punishment you can dish out, affords a five pound weight savings per set over factory a-arms. The tube adapters for mounting the rod ends (P/N 2309) or Roto-Joints (P/N 2312) are crafted from 4140 chromoly steel to enhance thread durability and guarantee years of trouble free use. A-arms are designed to work with the factory K-member and virtually all aftermarket K-members. UMI is proud to offer some of the strongest and most durable a-arms in today’s market. Crafted with pride in Philipsburg, PA- USA.
