      Video Review & Installation

      What's up, guys. Travis from, and today we're trying to figure out how to make it a little bit easier for you to get stuff in and out of the bed of your 2015 or newer F-150. Now thankfully Bestop has come up with a pretty cool way of doing so and that's thanks to their TrekStep Rear Mount Side Step. This nifty little step is a bolt-on kit. It's very easy to install, takes about 30 minutes. I'm gonna give the install a simple one out of three wrenches on my difficulty meter, get that out of the way. Now, this step comes in at around the $200 price point guys, and while there aren't any other options to compare it to, it's definitely worth it in my humble opinion.First off, it offers about 6 to 8 inches of drop and that's huge in my opinion because let's face it, even on a factory ride height truck, these step pads on the rear bumper, they're kinda high up, in my personal opinion, they're kind of slippery when wet. They just don't do a great job. This has a really nice textured grippy finish on here. So if you got mud on your work boots or it's wet outside, you're not going to worry about slipping on this thing.And if you think $200 is a little expensive guys, honestly, this thing is incredibly well-built. It looks very simple, but it actually can hold up to 300 pounds. Bestop figured out well if you're climbing in and out of that bed, you've probably got some heavy stuff that you're thrown in there, maybe lumber or cement or something like that, so you can safely stand at least two of me on there. That's more than enough. It's also made entirely out of aluminum and it features a black powder coat finish, so it's safe to say you're not ever going to have to worry about this thing rusting out on you and you're also not going to have to worry about the finish coming off anytime soon. And again, even if you do, because it's aluminum, no rust or corrosive issues whatsoever.Last thing to consider again is that install. I said it's very easy and it definitely is. You can actually install this on the driver's side or the passenger side. It's modular. You can flip it around either way to your liking and the step itself is actually adjustable left and right and again they do provide little spacers in the kit so you can actually do some up and down adjustments to your liking.All right, so again guys, if you want to make bed access a little bit easier and safer but you don't want to do a bunch of crazy cutting or drilling on your truck and no permanent modification whatsoever, then the Beststop TrekStep Rear Mount Side Step is going to be the ticket and if you decide to pull the trigger on this kit, come back in a little bit. I'll show you all the tools you need to dig out of the toolbox and then I'll walk you through that entire install step-by-step, no pun intended.All right guys, before we get started we'll need a standard drive ratchet with a 3/16 Allen key or Allen head socket. You'll also need a 16-millimeter socket, that can be shallow or deep. You'll need a 19-millimeter deep socket, a 21-millimeter short socket, and a 21-millimeter deep socket. You'll also need a hammer, a 22-millimeter wrench, and it's helpful to have a pry bar. Now, other optional but helpful tools include an impact gun with an impact swivel socket.All right guys, once you got your tools set up, you can lay the kid out on the table just like I have in front of me and I'll give a quick little explanation because it seems like there's more hardware than you need and that's actually for a good reason. You can make adjustments to the height of the step itself. So they threw these spacers in here. If you want the step to come down lower, you can throw these spacers on top. Now whether you use these spacers or not is also going to determine which set of hex bolts you use. You can see we have two very similar sized ones. One's slightly longer than the other one. You'll only be using the longer bolts if you're using any of spacers. We're not going to do that today. It's entirely optional. So we're going to be using these shorter ones. So you'll need two of these hex bolts and you'll also need this Allen head bolt here with the appropriate flat washers. What we're going to do first, we're going to mount the actual arm itself onto the linkage. The holes right here are pre-threaded so you don't need any nuts or anything like that, but you will need a 16-millimeter socket for the hex bolts and you'll also need a 3/16 Allen head key or Allen head socket for that Allen head bolt as well. All right, now when you go to fit that Allen head bolt, you're actually be using the smaller hole opposite of the two holes for your hex head bolts. Once you got those hand threaded, you can drive them home.All right, once you to have the linkage on the step assembled, you can come underneath here. We're gonna be removing our bumper support bracket. It's got three studs poking through the end of the frame rail here with these three nuts. You'll need a 21-millimeter deep socket to remove these. Now it goes without saying since we are removing hardware that secures the bumper to the vehicle, we want to play it safe, have it supported with a jack stand right here. Obviously the other side is still tight, but we are loosening this up so we don't want this thing falling down at all. Now you can probably get that top and bottom nut out of there with power tools, but you'll likely need a hand ratchet for that middle one. All right, once those nuts are free, you can remove the bracket. If you've never removed this bracket before, there are some flange washers that actually hold it in place. Just gently tap on the studs with a hammer. You should be able to pop it out of the frame rail. All right. If you're finding it difficult to tap those studs out with a hammer, you can also use a pry bar. Once you get it started, you can actually come up in here and get a little bit of leverage on the bracket.All right guys, now we're going to throw our step assembly in place. Before you do that, you want to grab these large bolts, put them through the holes like so and line them up in the holes with the frame rail where we originally removed our bracket. We want to get at least one of these in place. Go ahead and come up through the pocket, grab a flat washer and one of those nuts and get them both hand tight. All right. Once you have that hardware hand tightened, you can come in here. You'll need a 22-millimeter wrench for the nuts and you'll need a 21-millimeter socket for the heads of the bolts.All right guys. Now, this step is going to be dependent on whether or not you have a tow hitch installed. If you do, you're going to have to fill this third hole here for the bumper support. They do provide a bolt in the kit here. It's a 19-millimeter flange and they also have flat washers with a nyloc nut on the back. You'll need that same 22-millimeter wrench for the nut and then a 19-mill socket for the head of the bolt.All right guys. Now that the step assembly is secured to our bumper, now we can actually install the step itself. Now on the bottom of the lever or mechanism, if you will, you have this little recess in here and resting in that recess is this little aluminum block with these threaded holes here, so that's where your step is going to lay. You can make adjustments left or right depending on how far in or out you want the step to lay, but for this purpose, we're just going to set it right in the middle. Now as you keep that in there, you're going to grab the remaining Allen head bolts in the kit, these little small guys here, you're gonna thread them up through the bottom and you'll need that same 3/16th Allen key or Allen head socket to drive these home.All right guys, once you got the step in place, go ahead and test it out. Make sure it fits to your liking and that'll wrap up this very easy install. That also wraps up my review of the Bestop TrekStep Rear Mount Side Step fitting your 2015 or newer F-150. I'm Travis, thanks for watching. And for all things F-150, keep it right here at
