UMI Performance

We all know weight equals horsepower. UMI’s direct bolt-in replacement K-member and lower a-arm kit instantly removes 25 lbs of front end weight from your ride and helps your existing horsepower work for you. Strong dual tube construction and a host of high-strength features ensure the P/N 240131 will survive street use, drag strip blasts and autocross action. The K-member is fabricated from CNC machined 3/16” thick mild steel held together by a strong dual tube lower section. Factory clamshell and engine mounts bolt to the precision machined mounting pads while both factory and aftermarket suspension is located by strong boxed mounting points. Lightening holes are CNC machined into the mounting plates and the tubular construction provides added clearance for aftermarket exhaust. The k-member design permits stock spring and strut use while the lower a-arms feature a spring locating pocket. The lower a-arms feature TIG welded tubular construction, adjustable steering stops and polyurethane bushings. Street and track testing on our ’89 IROC test car has shown this K-member and a-arm kit to be strong, reliable and a great upgrade for your high performance ride. Available in tough powder coated red or black finish. Manufactured with pride in Philipsburg, PA – USA. Save $20.00 when purchasing these items as a kit!
