Very sturdy and installation reasonable. I reversed the assembly steps 12 as explained in earlier post because otherwise the holes did not align. Luckily I have clamps to pull it together to get the initial assembly completed. I gave it 4 stars because I paid a premium price and had to McGiver the installation. For the price I expect everything to go together as stated in the instructions without issue. Seems well built and carries my weight easily, time will tell.

75312-01A fits above referenced vehicle perfectly even though AMP says you need 75328-01A.You will need a 24 mm box end or open end wrench for the install. 24MM socket will not go through the holes..

Put this on my 2018 F-150, Fairly easy to install, very sturdy and it sits at the right height. makes it a lot easier to get into bed

Seems sturdy, but some of the bolt holes didn't line up. Some of the bolts should be torqued before installing on the truck. Can't get a torque wrench on them after installing.

Well built and sturdy. Not the cheapest but fits well and works well.

This will fit a '21 F150 with one small complication. The '21 F150 went up in size for the main two bumper bolts that this bracket fits on from I believe a 21mm to a 24mm. This is a small problem because the bracket hole to reach the bolt is drilled out just large enough fit a 21mm socket. To solve this problem you must use a regular 24mm wrench out the side of the bracket and do small, 1/8 turns to snug it up. Everything else fit perfectly and was easy to assemble and install.

I installed it myself, it was a pain, but I got it done, even though I am 74 years old. Would have been easier if I had a rack to put the truck on. It works and appears is sturdy enough to last. Time will tell.

The instructions noted that longer 14 mm bolts may be needed if an aftermarket hitch was installed. My 2017 F150 had a factory installed hitch, but I still needed to purchase 2 longer bolts. Metric bolts of this size were not available in my area. I assume that most F150 have a hitch installed. The convenient thing to do would be to include two bolts in the package to begin with, especially considering the expensivecost of the step. It was a pain-in-the-neck for me to realize I would need more hardware when I was in the middle of the installation process.

works perfect instructions were easy to follow

I knew I needed this step as my 4X4 bumper is high and with tailgate down it's too hard climbing up. This step is very sturdy and I just wish I had bought it sooner.

First and foremost, yes it does fit the 2021 model perfectly. I had a difficult time finding information on this, so for those that need confirmation, here you go. Tip - to get ready to install the two 21mm nuts on the bracket to bumper, use a low profile socket that you can slide in and out between the brackets. No need for a wrench, in fact, very difficult to install with anything but a socket. Second Tip - as you put together the bracket before install, keep all bolts hand tighten so the you can assemble and push the bolts through each hole with ease. Finally, the last tip, the actual step pad has a few positions to help you perfectly align it with the bumper end. Only negative, the instructions are a bit lacking.

I'm a shorter woman, and this makes it exponentially easier to get up in the bed of my truck without having to jump!
