Video Transcript for A Closer Look at the Romik REC-TP Running Boards

How's it going, neighbors This is Ed here with etrailer.com. Today, we're taking a look at Romik REC-TP and TB Running Boards. These are available as either a chrome running board with a raised black tread or all-black running board with a raised tread. These are available for a variety of vehicles. Use our fit guide to ensure you're getting the right fit for you. Now, when you add running boards to your vehicle, not only are you getting additional function where you're getting a easier step to get into the vehicle and additional traction when it's wet or slick outside, but in my opinion, I think you're adding a little bit of style and personal flare to your truck.

So as far as your area where you can place your foot, it's 5 1/2 inches across. You know, more likely, you're gonna hit it like that. And you're gonna have these raised nubs here made out of this polymer. Now, this is gonna hold up against any of the heat and cold that you experience, no matter where you are. Another cool accessory that they offer is actually a bracket cover to give you a more OEM finished look and hide your brackets.

No matter your fit, the boards will have the same style with the tapered edges, giving them a sleek look and a sporty design. The Romik REC Running Boards have a weight capacity of 300 pounds. Overall, the installation is pretty straightforward. We're actually setting up the brackets, we're using a different running board. But the process is exactly the same, it's just a different style.

So we're gonna get our installation started, and we're gonna grab a few different things to get this going pretty smooth. You're gonna need a torque wrench. You don't necessarily need one fancy like this. You can take a look at etrailer.com, we offer a little bit more less professional style torque wrenches that'll still get the job done. You're gonna need a few wrenches, well, a couple wrenches.

It would be handy to have a 15 millimeter and a 13 millimeter, as well as your ratchet wrench. And you're gonna need a 13 millimeter socket as well as a 15 millimeter socket. So now, we're gonna lay out all of our hardware. And the way that it works on both sides is pretty similar, you're gonna have three points of contact underneath. And I'm just gonna put together everything that I need for each one of those sections. So you're gonna have both your exterior bracket and the bracket that goes against the inside body on the studs. You're gonna have three of your 15 mil, I'm sorry, your 13 millimeter nuts, that go on the studs themselves. And then, you're gonna connect the lower bracket using your 15 millimeter hardware. So let's go ahead and hop underneath then get started. So the studs that you're gonna make your connection with your bracket with are right here underneath. You're gonna see that they're in different configurations, depending on if they're in the front, middle, or rear. One step that you don't wanna pass up on is actually cleaning the studs off using a M8 dye. You're gonna want to go through to get all the paint and the anti-corrosion off, so you can get a real grip with the nuts on the studs themselves. Now, you wanna make sure that this bridge is pointing away from the vehicle itself. And you can just use a 13 millimeter nut to hand tighten along the studs. Now, you don't wanna actually start snugging it down too much yet, 'cause you're gonna want this maneuverability for when you're getting the the running board on the brackets. Now, our bracket is adjustable, and that's one of the things that's really cool about this setup. But on the 1500 Ram, you have four position setups, and you can only go to the third hole. So you would not be able to get that highest level on this particular setup. However, you can go three up. And you can take your hardware, you're gonna use your 15 millimeter bolt and nut. I'm just gonna put them both through to kinda stabilize it. And then we're still just hand tightening. We still want it to be nice and loose, so we can position our Nerf bar a lot easier. I'm gonna go do the same thing on my other brackets. So as far as our running board, you can see that we have four sets of hardware along the track here pre-installed. On our 2025 Ram 1500, we're only gonna need three of these sets. So we're gonna be able to remove the end cap and just remove a pair of the nuts and bolts with the washers. So now, we're gonna just make sure we get it lined up close as possible to the location. And we're just gonna slide it on top of our brackets. And now, I'm gonna get underneath and make our connections with our fasteners. Now, I know you can't see right in here, but there's two 13 millimeter nuts that we're gonna fasten down. And it's gonna pull down onto the bolt that was pre-installed into our running board. So I'm gonna get a little tension right here. And I'm just gonna go through, I'm just gonna get everything just snug. And once I get all this tightened down, now, I'm gonna go and tighten down my brackets. So now that we have our running board attached to our brackets, we're gonna fasten down our actual bracket. So I'm gonna grab myself a ratchet and a box wrench, and we're gonna fasten this down to get the position that we want. So I'm gonna start in the center, and then just go through, and just still going just snug on everything, because we're gonna go back through with our torque wrench to make sure we get the specified torque spec. (wrench ratcheting) (wrench beeping) All right, and now that you have everything torqued down to the recommended foot-pounds from the manual, you're completely installed. Again, this is Ed with etrailer.com, taking a look at the Romik REC Running Boards. Have a great day.

See what our Experts say about this Romik Nerf Bars - Running Boards

  • How Many Brackets And How Sturdy Are The Romik Running Boards On 2024 Sierra?
    Robert, Romik does it right here. The Romik REC-TB Running Boards w/ Custom Install Kit # RMK99ER has brackets that are triple-point (front, middle, and rear), so each board has three evenly spaced steel brackets tying it to the rocker using factory holes. No sag, no twisting. And they slot into steel reinforcement zones behind the pinch weld, so they’re very sturdy (I've tested them myself). Did you have a bad experience with a cheaper kit that doesn't utilize all 3 mounting points? Also...

  • Will Romik Running Boards From 2024 Silverado Crew Cab Fit Double Cab As Well?
    Brianna, good catch! The cab size definitely matters here. The boards we’re talking about (Romik REC-TB Running Boards # RMK99ER) fit the Crew Cab version of the 2020-2026 Silverado/Sierra Crew Cab full 4 door, so the bracket spacing won’t match a Double Cab. But Romik does make a version specifically for the double cab with the # RMK96ER. I think you'll really like these! I tested them out and they are super lightweight and excellent quality, similar to Westin and others in that category....

  • Will Running Boards From 2024 Silverado 2500 Crew Cab Fit 2024 RAM 2500 Crew Cab?
    Hey Kirk, so the Romik REC-TB boards are going to be the same part number, but the installation kits are not. The part number for the boards is 5012209, and the install kit for the Ram is 2013. Romik can probably get you that kit, we don't have a way to sell it separately as of 7/30/2025. For complete kits, you can look at the following: -2024 Silverado 2500 crew cab # RMK99ER -2024 RAM 2500 crew cab # RMK96DR Hope this helps. It may be easier to just leave the boards on the Silverado...

  • Will DEF Tank Interfere With Installing Romik Running Boards On 2023 Silverado 2500 HD Duramax?
    James, that’s a smart thing to check. Romik designs their brackets to clear the DEF tank on HD Silverado models, no tank relocation needed. Just be sure you’re using the Romik part number matched specifically for the Crew Cab configuration, which is the # RMK99ER. We’ve had folks install these on plenty of diesels without a hiccup. I've attached a video where my coworker Ed walks you through the simple install process! How do you like the Duramax? That should be able to pull just about...

  • Nice Running Boards For 2024 Silverado 2500 Crew Cab Diesel That Goes Mudding
    Luis, excellent questions and an even better selection with the Romik REC-TB Running Boards w/ Custom Install Kit # RMK99ER.
