Don’t lose horsepower by bolting your blueprinted engine directly to twisted frame mount tubes. This billet sub plate is CNC machined from thick stock to stay flat and true when tightened. Wing clamps are also made from sufficient stock to not bend or rotate, spin off the frame when tightened.

MM-1A Motor mount sub plate, American 3” rail center spacing.

MM-2F Motor mount sub plate, Foreign 3 ½” rail center spacing.

Please specify which size you want after purchase.
