Excellent quality wheel spacers. I installed ECCP 2' wheel adapters on all four wheels of my 1995 Ford F150. Installation was fairly easy, each spacer comes with its own nuts that sit flush and flush with the axle surface. They are very strong and durable with solid construction. Overall although I am very happy with the product it is good value for money and I am very comfortable driving my truck with these wheel spacers. I will update this review in a few months but so far very pleased. I suggest using threadlock or Loctite on the nut threads to prolong life and prevent rusting.
