Product details
UMI’s fabricated tubular a-arms provide a rock solid foundation for your 4th Gen’s front suspension. Our P/N 2307 a-arms are built to offer smooth travel, a precise steering feel, and an 8lb weight savings over stock. The DOM 1-1/4” diameter tubular sections are precision bent, CNC notched and TIG welded to the ball joint cup featuring our double strength configuration. UMI built 4130 CrMo tube adapters provide a durable attachment point for the high misalignment rod-end while the other side features an ultra smooth, bind free Delrin bushing. The combination of Delrin and rod end make for a performance oriented a-arm with street tendencies. The spring and shock attach to the arm via a tough 1/4” thick steel shock mount. The CNC machined ball joint cup is attached and a premium ball joint is installed. UMI’s tubular lower a-arms can be installed on the factory k-member or any aftermarket k-member as well as the factory spindle - making this a true bolt-on product.
