Video Transcript for Review of Bestop Nerf Bars - Running Boards - Toolbox Step - B7531215

Today we're gonna take a look at the Bestop Trekstep. Now, this is going to be an easy way to get in and out of your truck bed. With this mounted it's going to just stay flush up against your bumper, but then whenever you need it you just press down on it with your toe and it'll deploy out. So now we have an easy to use step to get up into our truck bed, adjust anything we need to, get anything off our ladder rack or maybe out of a toolbox, hook up our fifth wheel, whatever it may be.Something I like about this is that we can adjust the step forward and backward by loosening the bolts at the bottom. This will actually slide in the track so we can get it adjusted to wherever we need it to be, if that's closer to the cab, maybe closer to the tailgate. And then it also comes with a couple of spacers so that we can get the height adjusted to where we want it.

So if you want it a little bit taller, a little bit shorter, you can get that dialed in there.Everything is gonna be made of a nice, durable aluminum. The arm is gonna be made of an aluminum alloy with a black powder coat finish, and our step is gonna be made of an extruded aluminum. So you don't have to worry about any rusting or corrosion, but it's still gonna be very durable and relatively lightweight.It does have a weight capacity of 400 pounds, but that's pretty much plenty for just about anybody that's gonna be using this step. No worries about this wiggling on you. It's a really secure, solid step.

I've used these before. They make it really easy to get up and into your truck bed. No problem.Now, this is for the passenger side. There's also a driver side available if you wanna get that one instead, or pick up both so you have a step on either side of your truck. You can do so.

The part number for the other step for the driver's side is gonna be B7531115.Now, this is gonna be a custom fit for the 2017 through the current model of Ford F250 and 350 for the crew cab, regular cab, and super cab. And it's also gonna fit the 2017 through 19 Ford F450 for the regular cab. Or excuse me, for the crew cab.The step itself is gonna have a nice rugged finish. It's gonna be kind of a medium grade sandpaper type finish, so it'll give you some nice, nonskid action there. The step is pretty wide.

It's about 11 and a half inches across by 6 and a half inches. So you should have plenty of space, even if we wanna put both feet up there to get in and out.As far as the height, it would kind of depend on how you have this configured. But overall from the bottom of the bracket to the top of the step . Get my tape measurer out here. It's about roughly 9 inches. So it'll bridge the gap there between your bumper and that high bed side. Again, weight capacity's 400 pounds.I think this is a really nice, well made step. It looks good. Bestop is a pretty well known brand, so it's gonna do a great job for you for a long time. That's gonna do it for our look at the Bestop Trekstep for the passenger side.

The step works well and wasn't too difficult to install. Some LockTite should be added to make sure that vibrations do not cause some of the screws to loosen.

2020 Ford F-250 Super Duty

Easy install. I ordered the driver side and it is on back order until late October, so I placed another order for the passenger side since it was in stock. Works great and looking forward to getting one for the driver side.


Great product and easily installed


Works great. Instructions provided incorrect wrench sizes but installation was relatively easy.

2019 Ford F-350 Super Duty

See my review on the drivers side step.


Works good, no issues.

  • Is There A Retractable Rear Step Available For A 2022 Ford F350 Super Duty 8 Foot Bed
    I recommend going with the Bestop Trekstep rear mounted truck rear # B7531215. It is a spring-loaded side step.

It can hold up to 300 pounds and the dimensions are 11-1/2 inches long by 6-1/2 inches wide. Installation instructions are below:

  • Rear Bumper Step for 2019 Ford F-450
    I can understand why this is so confusing. The Bestop TrekStep # B7531215 for the 2019 Ford F-450 is a side step, not a rear bumper step. Because of some variations at the rear of the vehicle there are some rear mounted steps that are available for the F-250 and F-350 Super Duty, but not the F-450. If you wanted a rear mounted step for your Ford F-450 your best bet is to go with a hitch mounted step like the Curt Trailer Hitch Mounted Step # C31001 which works in 2" hitches. You could go...

  • Driver Side TrekStep that Fits 2018 Ford F-250
    For the driver side of the Bestop Trekstep that fits your 2018 Ford F-250 you'd want the part # B7531115. The part # BWRHXA2182 would work great to reduce your 2-1/2 inch hitch to a 2 inch hitch as well.

  • Recommended Bed Step For 2017 Ford F-350
    For your bed step, I recommend the HitchMate TruckStep Extendable, Hitch Mounted Step for 2" Hitches - 9" x 6" - 500 lbs # HE4045. This mounts into your trailer hitch receiver and gives you an adjustable step to use when the tail gate is open or closed. There is a slightly larger version # HE4037. For a side step, I recommend the Bestop TrekStep - Rear Mounted Truck Step , made of Aluminum , for the passenger side, Item # B7531215 and/or the Bestop TrekStep - Side Mounted Truck Step,...
