Well this product didn't fit my wife's JK as it was delivered it was too short for her needs at 1.5 inches. It's still a quality product so I'll still give them a good rating. She has Fuel Beast 20x12 wheels with -44 offset on MT 35x12.5R20 fuel tires. The distance is 5 inches from the tailgate to contact with the tire. I ended up adding 2 hockey pucks, cut off the tab that needed to be pressed into the tailgate, then drilled holes for a 1/4 x 20 x 4 inch bolt with a 1/4 x 20 rubber nut. The rattling has mostly stopped.
