This is OEM parts with a PERFECT FIT
This is OEM parts, perfect fit. Only modification to the installation instructions was I cut the 4 holes first so I could wrench from the top as well as the bottom. Also, they recommend lifting the bed 6 Inches to work on it, you only need a 2x4, or 1.5" lift worked just fine. Installation is simple but it does take time, there is 4 units to install and 8 bolts on the bed that are factory torqued.
