UMI Performance Double Adjustable Front Shock GM Body 67-79


UMI Performance

Model #B234

UMI began in late 2002 under the leadership of Ryan Kirkwood and the guidance of his father Denny. Together this father and son team developed a large variety of products for many makes and models of GM vehicles as well as the Ford Mustang. Ryan saw a large demand for suspension and chassis products, and felt the market was lacking of options. On May 31st 2003, UMI began its official journey in the aftermarket suspension industry with their first test car, a 1994 Ford Mustang GT. This car was used as a test bed for the beginning stages of UMIs Fox and SN95 platform products. The products began to move very quickly, becoming almost impossible to keep in stock. The faster they manufactured them the quicker they sold. In late 2003, UMI purchased a 2000 Pontiac Firebird which was used as their F-Body platform design vehicle. Slowly, products began to arise on the market for the GM F-Body, and quickly UMI became a well-respected company, becoming one of the largest suspension manufactures in todays market.
