Most Popular Rack Lock for 2021 Ford F-150

I used 2 inch square tubing cut the length of the tie down support bracket in my 2007 Honda Ridgeline and secured with a stainless bolt and wing nut, use a large enough washer to cover the diameter of the supply hole in the Honda Ridgeline bracket on the truck. A couple of notes: Be sure to use something as a cushioning gasket to insure a snug fit and to protect your truck lining. I used rubber or foam exercise mat cut to the same as the aluminum square tubing. Use a washer that a combination of hard plastic and metal to avoid the corrosive effects of dissimilar metals in contact with each other. last: My 26" full suspension bike fits, but I have swing it to one side slightly before i close the tailgate and lift the bike up and slide it down....It's a very snug fit but the suspension adds pressure to the tailgate and its works out very well. Or you could just use a tailgate extender.

Referring to special mounting instructions if you have a bed liner: (line #3). I do not have a bed liner, but I do have a molded plastic cap on my bed rails ('04 Ford F350). The first install over the plastic cap the locking pin or pin as called out in line #3 was nowhere near making contact with the metal lip of the metal bed under the plastic. What I did next on the second and final install was remove/cut away the plastic on the inside of the bed rail to allow the vertical portion of the "L" mounting bracket (Fig 4) to contact the metal bed. The locking pin is now at a position almost where it would protrude under the metal bed lip if I would remove the rest of the plastic under the horizontal portion of the "L" mounting bracket, I did not do that. After cutting a notch in the metal rail to accept the pin, the pin barely flushes out to secure the rack. A 1/4" longer pin would take care of this problem. One other thing that was not addressed in the install instructions was if you have a full size pick-up bed you are likely to attach the passenger side fork mount (Fig 2) to the right of the extension tube locking mechanism. The extension tube is a smaller diameter, so you will have resize the fork tube clamp (Fig 1) for the smaller tube. I can't explain how to do it other than it's a Chinese puzzle.

rack tends to work itself loose from bed walls during long trips. had to strap down with ratchet straps to keep from moving. locks only work at a specific angle -- wish the manual had said this because we couldn't lock our bikes until figuring it out.

Excellent Customer service and help for this product. Thank you Carol and Neil your the best.
