BAKFlip MX4 Installation

Once you’ve decided on and received your BAKFlip MX4 cover, then comes the seemingly tricky part of installation. No need to fear, we’ve put together a comprehensive step-by-step guide to install your premium truck bed cover. We’ve streamlined the process, taking out any difficulty and/or confusion.

Step-by-step Instructions for Installation

While Installing your own BAKFlip MX4 truck bed cover may seem daunting, it doesn’t need to be overwhelming. Our experts have put together this step-by-step guide to install your truck bed cover:

  1. If the truck does not have a drop in bedliner, install the cab/bulkhead seal (weather strip). Wipe painted surface with isopropyl alcohol before applying. If the truck has a drop in bedliner, no seal will be needed.
  2. Close tailgate. Place BAKFlip rail on truck bed with silver bracket all the way forward and toward the center of bed. (Refer to enclosed Spacing & Shimming Sheet for more details). Rails should be completely level.
  3. Make sure the rail is clamped square. Start at the front, and place the first clamp approx 6 to 9 inches back. NOTE: Some drop in liners may require trimming in the corners to fit the rail in the opening.
  4. Make sure the clamp is inserted all the way up into the rail and clamp teeth are aligned to rail slots to ensure a secure grip.
  5. Apply downward pressure to the BAKFlip rail when tightening the clamp to ensure the rail sets flush and seals properly. A second set of hands may help.
  6. Place the 2nd clamp near the center of the rail. See steps 4 and 5 to ensure the clamp goes on correctly. (8’ beds-evenly space 2 clamps between ends).
  7. Place the rear clamp approx 6 inches from tailgate. Tighten all the clamps until snug. Then torque an additional 1/2 turn (approx 10 ft/lbs). Repeat steps 2-7 on opposite side.
  8. Clip prop rods to their ball mount on the rail.
  9. Set the cover in the folded position on the BakFlip rails towards the front of cab with the small panel forward.
  10. Before mounting the cover on the truck, install the two buckle ends into pre-drilled holes on the front header with the provided machine screws and threaded posts using a screwdriver. DO NOT use a screw gun, securely tighten BY HAND only.
  11. Install the three cab bumpers along the top edge of the cover where it meets the truck cab.
  12. Insert the large flat bolt with the supplied rubber washer through the front panel and silver slotted bracket underneath. Repeat on the other side.
  13. The large flat bolt goes down through the front panel on each side. Underneath the cover, the order of washers is as follows: rubber washer first, then large flat stainless washer, then the lock washer, and finally the 5 star finger knob as shown to the left.
  14. Assemble the washers from underneath and loosely tighten the knob. Do not over tighten.
  15. Unfold the cover towards the tailgate. Make sure the cover fits squarely between the rails.
  16. The covers aluminum frame should fit just inside the tailgate when the adjustment is made correctly (approx. 1/4” clearance).
  17. The flap seal will rest on top of the tailgate.
  18. Once 20 positioned, fold cover over toward cab and tighten the knobs until the lock washer flattens out and locks the knob securely to the bracket.
  19. Route the front drain hoses from the end of the BAKFlip rail out through manufacturer available bed plug. Simply remove these plugs or drill a 7/8” hole through the plastic. If you have a drop in the plastic bedliner, simply run the drain tubes behind or under the liner.
  20. Check to see that cover panel latches and makes proper contact with side rails.
  21. Occasionally, the side seals of your BakFlip cover will appear wrinkled shortly after initially installation of the cover. To keep seals laying flat, you can leave your truck in the sun, or to expedite, simply apply heat with a hair dryer or heat gun. See this video for a good look at how it’s done.
