UMIâ€™s fabricated tubular a-arms provide a rock solid foundation for your 4th Genâ€™s front suspension. Our P/N 2308 a-arms are built to offer increased rigidity, smooth non-binding travel, a precise steering feel, and a 4 lb weight savings over stock. The DOM 1-1/4â€ diameter tubular sections are precision bent, CNC notched and TIG welded in a jig to form the solid base. The in-house built 4130 chromoly tube adapter provides a durable attachment point for the UMI Roto-Joint which mimics the action of a rod end without the noise and harshness. The in-house built Delrin bushing provides a smooth non-binding upgrade to the industry standard polyurethane bushing. The unique combination of precision and comfort from the Roto-Joint and from the Delrin makes for a great racing oriented a-arm with a few street tendencies. This is the ultimate hybrid arm for street/racing use. The spring and shock attach to the arm via a tough 0.250â€ thick steel shock mount. The CNC machined ball joint cup is attached and a premium ball joint is installed. Our tubular lower a-arms can be installed on the stock K-member or any aftermarket K-member as well as the stock spindle – making this a true bolt-on product. P/N 2308 is available in brilliant red or black powdercoat and also with a chromoly option (P/N 2308CM â€“ see below*). Manufactured with pride in Philipsburg, PA â€“ USA.
