Spohn Performance's front lower a-arms set a new, higher standard of performance and quality. When they designed these a-arms, they had two goals in mind. One was to provide the performance capabilities needed for the toughest race tracks, the second was to provide the strength and durability required for the demands of a daily driven vehicle. We're proud to say that we have accomplished both. Spohn's front lower a-arms are a true "A" arm rather than a "V" arm. This provides maximum rigidity and equalizes forces delivered in to the k-member. Spohn control arms are gusseted in critical areas to ensure that a weld never breaks. The Spohn front control arms can be installed on a stock k-member, or on aftermarket k-members. They decrease overall weight, and more importantly - "unsprung" weight.
