The 4 link mounts are the same as a back half would be. A 4 link was designed to be able to plant the tires without planting them too much and riding wheelies, in these heavy trucks we need all the help we can get.
My buddy is buying a reg cab 6.4 2wd this weekend. what would be the most effective and cost efficient way to get the most traction as possible. I understand it would need slicks ad well.
