5/ 5stars
Zone offers a great kit for the Super Duty. I was impress by how beefy the components were. The instructions were clear with an adequate amount of pictures. There are a few things that are assumed in the instructions that would need spelled out better for a beginning wrenched, bit overall not bad. Installation was completed in about 8-9 hours working casually with breaks. And taking time to paint things along the way. Great kit.
