High quality with a perfect fit. An impact wrench (and torque wrench) makes the job a lot easier. It took me and my son about 45 minutes to make all four wheels. After I installed the Bushwacker fenders, the stock wheels really did look like they were recessed into the wheel wells. As you can see, 1.5 inches really helped without looking nasty. These spacers work well until the lift/wheel is replaced.
