Download 2007-2011 Toyota Tundra Super Rail Mounting Kit Installation – MOUNTING BRACKET INSTALLATION INSTRUCTIONS 1. Verify the part numbers listed on the shipping carton and check part quantities using the Parts List on page 11. 2. Remove the spare tire. 3. Layout the bed according to the layout or template method drawing on the previous page, marking each hole carefully. 4. Cover each slotted hole on the top flange of each mounting bracket with transparent tape. 5. On the rear driver side, remove and retain the front bolts on the factory hitch receiver bracket. See Installation Photo #3 on page 9. 6. Slide the rear driver side bracket (#442003) between the frame and the factory hitch receiver bracket. 7. On the rear passenger side, remove the front two bolts on the factory hitch receiver bracket, and loosen the rear bolts to allow the mounting bracket (#442004) to slide more easily past the shock tower. 8. Loosely reinstall the factory bolts removed on Steps 4 and 6. 8. Clamp the front brackets to the frame. Position as seen in the figure on Page 7 and on Installation Photos 1 and 2 on Page 8. 9. Using the marked holes in the Bed Layout as a guide, drill a 1/16″ hole through the bed beginning with the driver side front holes. 10. When the pilot hole is drilled through the bed, the transparent tape will be pierced by the small drill. It should be centered front-to-back of the bracket’s slotted hole. 11. Drill each of the marked hole locations, preferably using a step drill of at least 3/4″ diameter. (A step drill is a cone shaped bit that has a variety of gradually larger diameter sizes the deeper the drill is used).
