Free Shipping!


We all know weight equals horsepower. UMI’s direct bolt-in replacement K-member instantly removes 20 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 2403 will survive street use, drag strip blasts and autocross action. The K-member is fabricated from CNC machined 3/16” mild steel held together by a strong dual tube lower section. Included fabricated motor mounts are used to bolt any LSX engine 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 modular design permits stock spring and strut use or simply remove the spring pockets and convert to coil-overs. Street and track testing on our ’89 IROC test car has shown this K-member 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

Note: Factory low mounted LS A/C needs relocated when running a UMI tubular k-member, we recommend an A/C relocation kit from kwikperf. K-member was designed around the LS1 oil pan and also works with the Holley 302 oil pan. Other oil pans may not clear. P/N 2403 k-member can also be used with a factory SBC engine by not installing the included LSX motor mount stands.
