Ford SuperCrew F-150 2004-2008 SuperRail Mounting Kit #3113 PDF Manual

Truck Preparation
1. Check part quantities using the Parts List on Page 2.
2. Block vehicle wheels. Some vehicles may require you to raise the rear of the truck in order to make it easier to drill for installing the mounting brackets on the truck frame.
3. Remove the spare tire and tailgate.
4. You may wish to remove the wheels to give yourself greater working room.
5. Remove the bolts that attach the receiver hitch support bracket to the frame on 2004-2005 model year trucks.
NOTE: On 2006-2008 models, the receiver hitch support bracket is welded to the frame. For this reason, we have included four rear mounting bracket nut plates {Q} to aid installation.
