How to Install a Bakflip HD Tonneau Cover on a Ford F150

Things you should know when installing a Bakflip HD truck bed cover on a Ford F150 pickup truck. You want to make sure it fits right to keep it operating properly so watch the video below.


  1. 1
    Place the rail of the Bakflip HD on right hand side bed rail of the F150. Slide the tonneau rail all the way forward to the bulk head. It is a good idea to have a squeeze clamp or similar to hold it in place.
  2. 2
    Place the included rail clamps in place. Tighten with a wrench or socket. Hold down firmly on the rail while tightening.
  3. 3
    Do the left side rail the same. Remember to hold down firmly on that truck bed cover rail while tightening to ensure a nice snug fit to keep the weather out.
  4. 4
    Install the drain tub. To do this, drill the appropriate size hole in the plastic plug in the front lower corner of the truck bed. There is one on either side. You may have a bed liner so you will have to drill a hole through both the bed liner and the plastic plug.
    • Now run the drain tube all the way through the plastic plug and bed liner if you have one. Connect the end of the drain tube on the drain nipple underneath the rail. Do both sides.
  5. 5
    Place the Bakflip HD pickup bed cover in place between the rails in the folded position. Make sure the 6–8 inch (15.2–20.3 cm) panel of the cover is in place near the cab.
  6. 6
    Slide the folded cover towards the cab. Move it along until the bolt holes align with the holes in the cab end of the side rails. Install the bolts provided, on either side of the cover in these holes. Place the rubber washer first then the flat washer and then the lock washer and the star nut on loosely. Do not tighten yet.
  7. 7
    Unfold the cover to the closed position. Make sure the tailgate is closed before unfolding the last section down onto it. Make sure the cover looks all aligned. Open the tailgate, crawl up inside being careful not to move anything and tighten the two star nuts.
  8. 8
    Find the three rubber strips provided. Place them underneath the last wide panel near the cab so that when the cover is folded open the rubber strip keeps the open Bakflip HD from hitting your truck cab.
  9. 9
    Close the cover. Make sure everything works properly and make adjustments if needed.


  • If you find the weather stripping wavy and not sitting flat, you can wait until the sun hits it and it will flatten out with the heat or you can run a hair dryer along it smoothing it out with the flat of your hand. Be careful not to over heat the rubber with the hair dryer. Do not use a paint stripper to heat up the rubber.


  • Make sure the star nuts are tightened snugly but do not over tighten. As a precaution check the nuts now and again to make sure they did not loosen.
