These notches are built from 3x3 square tubing 1/4 inch thick mild steel. They are very strong and are designed to let your truck lay full frame with bagging. They are also used a lot when customers are doing coil over setups to make sure they get plenty of axle clearance. The one piece design makes the install very simple.
