This is an easy to assemble and install step notch kit for your frame. Typically used in the mini truck market to drop the frame past the rear axle. 2-5/8″? wide outside. 6-1/2″? from the top of the original frame to the top of the notch.
The notch depth will vary, depending on how tall the frame rails are, and what sweep the original frame rails have. The S10 we used for our installation article, for instance, has 4” of axle clearance when the frame is laying on the ground. The measurement was taken with 18”wheels.
