Perfect fit for my 2015 JKU 4 door with the hard top removed. The only design flaw, however, is the rear attachment piece. It has 2 elastic cords to hold it on the taillights and a strap for the middle but the lid only covers the tailgate maybe 1/2 inch so sometimes in heavy rain it gets into the tailgate and water spills into the trunk . hold. It is painful to constantly suck out the water. I bought a strong magnet to hold the lid over the tailgate and now it works great!
