To give that oversized truck a real riding partner. When it comes to your pickup truck, Jeep or SUV, if it's "go big or go home," ARIES Big Step 4" round side bars hit the nail on the head. For a solid truck, you need solid truck accessories that can stand up to the rough and tumble of the off-road trail and still look good sitting in your driveway. ARIES 4" round side bars are made to be bigger, bolder and stronger. ARIES design them to be a heavier-duty side bar option that installs easily, provides reliable footing for making that climb and perfectly complements lifted and full-size trucks. ARIES offer Big Steps in two finishes, including textured black aluminum and polished stainless steel, because when it comes to your truck, ARIES think size should matter.

Vehicle-specific design. ARIES Big Step 4" side bars begin with a vehicle-specific design. From the Ford F150 to the Chevy Silverado, ARIES make 4" round side bars for specific makes and models, giving them custom bends, custom-placed step pads and vehicle-specific mounting brackets. The unique shape of each side bar allows for perfect contouring to the body of the truck, and the custom position of the step pads offers optimum functionality with the truck's layout. The mounting brackets of Big Step side bars are made from high-strength carbon steel and bolt to pre-existing factory holes on the frame to eliminate drilling and speed up installation.

Solid construction. ARIES Big Step 4" round side bars are designed to go hand-in-hand with our Big Horn bull bars, featuring a bold 4" diameter and giving you an aggressive look for your truck. They are available in a unique aluminum option from our Alumalite series, or in 304 stainless steel. Our aluminum side bars are 40% lighter than carbon steel and offer excellent strength and rigidity. They are also totally impervious to rust and corrosion. ARIES aluminum 4" side bars are coated in a textured black powder coat finish for lasting protection against scratching and scuffing. Our 304 stainless steel side bars, on the other hand, are constructed to be high in nickel content, giving you the strength of steel with excellent corrosion resistance. ARIES 4" round stainless steel side bars come with a polished finish for a lasting shine.

Custom, raised step pads. Not only are the step pads of ARIES 4" round side bars placed in custom locations to complement the layout of your vehicle, but they also offer superior comfort for your foot. With a raised, flat pad that covers a large portion of the side rail's width, the step pads provide a generous surface area and are textured to resist slips, even when wet. The step pads are made from tough polypropylene that will not crack over time, and they are fitted with a brushed stainless steel insignia, bearing the ARIES name.

Aries Side Step
Was very easy to install, look great and very sturdy. Side steps themselves are very light aluminum, which worries me that they are light gauge aluminum, but seems strong enough so far. Needs better instructions identifying which nuts and washers are for side step vs bracket. Would recommend for sure. Better instructions for installation needed.

Absolutely Awesome Looking
There are probably some of the best looking bars I have seen on any truck and I got them at a super price, I really lucked out finding these and deciding to give them a shot. I initially thought they would look a little big for my Tacoma, but they look awesome on the off-road Baja edition. This was the first time I have purchased anything from CARiD and they have been awesome to deal with and are now the first place I go when I am looking for truck accessories.
