UMI Performance 70-81 GM F-Body Leaf Spring Front Mount

This UMI Performance leaf spring front mount is what you get in the box: the mount itself and the necessary hardware to install it. It bolts right into the factory location on your 1970-1981 GM F-Body, like your Camaro or Firebird. This part is key for controlling how your rear suspension squats under acceleration, which is a big deal for handling.

What makes this mount stand out is the choice of two mounting locations. You can use the stock hole, or you can use the additional ¾-inch raised hole. This raised hole is often called the “Herb Adams mod,” and it changes the anti-squat geometry of your rear suspension. Using the raised hole lowers the rear of the car slightly and can improve traction off the line. It’s race-proven, meaning it’s been tested in demanding situations, and it’s made right here in the USA.
