Review on Enhance Off-Roading Performance with Rugged Ridge 15201.08 Wheel Spacer Kit - 1.5 Inch, 5x4.5 Bolt Pattern, Black Finish by Eddie Man

Good quality for the price. The included nuts are 21mm hex, which is a bit annoying. The nuts also have a black oxide finish that rusts fairly quickly. I had to use the existing tabs in the recessed holes (3/4" hex size, standard size for 1/2"-20 bolts). I've driven it about 7500 miles. Don't forget the thread lock.
