When they first landed on the moon, the astronauts declared it a small step for man, and a giant leap for mankind. Likewise, when Aries decided to make the largest 4" round nerf bar known to man, they declared it the Aries Big Step Round Nerf Bars.

Crafted from huge 4" diameter steel tubing, these are some of the biggest side bars around. The elevated step pads deliver an even bigger boost, and feature a non–skid top for sure traction.

Thanks to vehicle–specific mounting brackets, the Aries Big Step Side Bars boast a perfect fit. Plus, the easy installation means no drilling or cutting is required. That way, you're stepping up to the big time—in no time! What's more, Aries backs your Big Step Nerf Bars with a 5-year warranty on black powder-coated aluminum and a 3-year warranty on black powder-coated steel nerf bars.

2016 Ram 2500 CrewCab

The steps are great and were easy to install. Being aluminum they are light enough I was able to hold the bar easily with one hand while bolting it on with the other. The only problem was the instructions did not match my truck, but they are close enough that it might have added 5 minutes to the install at most. I am 6'2" and my wife is 5'3" and they work great for both of us. Factory the truck was to tall for us to get in and out of easily but these made all the difference.

Looks sick

Let me start by saying that they do fit a 2012 ram 1500 crew cab, not sure why the only options are for 2500 and 3500. The textured black looks sick on my silver ram. They were super easy to install, took about 45 min....found a video on line from Aries. Super solid, I weigh 225 and I can jump up and down on them and there is no give at all. All in all very satisfied.

Aries Black 4" Round Bars

Very solid nerf bars. Look good, seem to be well built. Only reason for less than five stars is that at least one side was previously drilled on top for different step-plate locations, then attempted to repair those holes. The texture and repair were quite different than the normal finish (mine are textured black aluminum). Doesn't look as professional as I feel it should. A little attention to detail would have changed my review. For the money, good product thus far.

Great product, poor instructions

I have the nerf bars on my 2012 F150 and they look and function great. Maybe I'm in the minority but upon inspection they looked interchangeable and there was nothing labeled that showed one differently however there is a difference, I found out the hard way and had to switch them around because the steps were just off by 4-5 inches. The instructions were still not the best could be a lot more helpful and all of the sizes of nuts, washers and bolts are all in one big grab bag.
