UMI’s drag specific tubular a-arms are built to perform. They feature lightweight CrMo construction with UMI’s exclusive double strength ball joint cup and include a double shear mount for a limiting chain. The P/N 2300 saves 4 pounds per side compared to stock and is perfect for the front of that single digit drag car! The strong 1-1/4” diameter tubular sections are precision bent, CNC notched and jig welded to form the a-arm. UMI built CrMo tube adapters provide a durable attachment point for the premium Teflon lined race quality rod ends (includes high misalignment rod end on back strut). The spring and shock attach to the arm via a tough 1/4” thick steel shock mount. UMI’s tubular lower a-arms can be installed on the factory k-member, on UMI’s k-members, or any aftermarket k-member and uses the factory spindle – making this a true bolt-on product. Manufactured with pride in Philipsburg, PA – USA.
