    “Innovation In Motion”. That’s the motto of AMP Research. Founded in 1980, this American design and technology company has always lived up to that motto. When it comes to the automotive industry, they definitely deliver.

    If you need a side step without the drawbacks, check out the AMP Research PowerStep. It’s a retractable truck step/running board that automatically extends when you open a door. Once the doors close, it tucks itself under the vehicle for improved aerodynamics, ground clearance, and style.

    Make it easier to get to your truck bed. Mounted under the rear bumper, the BedStep does just that, even when the tailgate is open. The BedStep2 mounts just behind the cab and in front of the rear wheel and provides a safer and easier way to access cargo from the sides. Both are retractable for your convenience.

    We work hard to ensure that the prices of our aftermarket truck bumpers are the best available online. That’s why we guarantee that you’ll get the lowest price on all of our bumpers and accessories. Here’s how it works:

    • We guarantee that the price of our aftermarket truck bumpers is the best available online. If you find an online store that offers a specific model at a lower price, let us know and we’ll match their price for your purchase.
    • If you find that the exact bumper at an even lower price online within 6 months after your purchase, we will refund you the difference. Simply send a price difference refund request to support@bumperonly.com. This applies even to the prices from our own store at BumperOnly.com
    • The competitor must be an online retailer with no physical stores and they must be an authorized dealer of the bumpers or accessories in question. The competing online store must also have the product in stock on their website for our price match guarantee to apply.
    • The price match guarantee does not apply to online marketplaces such as Amazon, eBay, Overstock or any other similar websites. The competitor must be selling the item directly on their own online store.
    • Additional promos cannot be applied in addition to the price match guarantee. For example, the free gift promo cannot be added on top of the price match guarantee. Only one promotion can be applied per purchase.

      Bad A** Bumper

      It looks amazing on my '03 2500HD. One of the main brackets has two weird nuts attached to a tab that have to be taped into place. Once you slide the brackets into the frame of the truck, you need a way to hold these tabs in place so you can thread the bolt from the underside. ICI should just weld this piece to the bracket. It was a pain to get the sides even because of these tabs, but other than that, the final install looks great. I installed a 12k winch. Since there's only one way to mount it to the bumper, which is to use the same holes that the roller fits into, reaching the winch controls can be an issue. There are two frame supports now unused, which I can Fab a winch mount for, if the current set up is too user unfriendly. Bottom line...great looking bumper, very reasonable price. Needs some design tweaks. I was a bit annoyed that it sat with the freight company for almost a week, due to "lack of driver's". Other than these minor gripes, I love the look and style.

      ICI Magnum Front Bumper w/Winch Assembly

      Built like a tank, nice finish - haven't installed yet till I get all the extras. Don't know how it will look once installed. Will update. Comes in a huge crate for 2 people to move.


      Thought it was a very nicely built bumper, would buy another one and recommend this unit to others.

      Looks good

      Took a while to get built but once I got the email that the bumper shipped, I got a call to schedule delivery the next day! The unit installed quite easily, though, I did have to drill out 1 hole on my frame 1/8" to fit the passenger side bracket. Getting the clearance just right was a challenge, and, after all final adjustments I still get contact with the grill. All in all i'm satisfied with this purchase.

      Awesome bumper

      This bumper is awesome took the appearance of my truck to a hole new level.
