UMI’s fabricated tubular a-arms  provide a rock solid foundation for your 4th Gen’s front suspension. Our a-arm  kit is built to offer increased rigidity, smooth non-binding 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 in a jig to  form the solid base. In-house built 4130 CrMo tube adapters provide a  durable attachment point for the premium Teflon lined race quality rod ends.  The spring and shock attach to the arm via a tough 1/4” thick steel shock  mount. The CNC machined lower ball joint cup and CNC laser cut upper pad feature  premium ball joints installed. UMI’s tubular lower a-arms can be installed on  the factory k-member or any aftermarket k-member as well as the stock spindle -  making this a true bolt-on product.
