The Motobilt Jeep JK Micro rear bumper is CNC cut and formed out of 3/16 inch plate. Four holes in bumper are to clear the hit bolts because it fits tightly to the frame. Micro bumper has a cut out for a 20 inch single row light bar designed for a light bar measuring 21.5 inch wide at the mounting surface.
Bumper does clear factory style receiver hitch. You will have to slightly trim off the frame on the back. Only minimal trimming required in a way where if you want to change bumpers in the future, it will not hinder other bumper fitment. Ships bare metal so you can paint or powdercoat the color of your choice.
