"I have a 2003 GMC 1500HD Crew Cab that I purchased new and have wanted to put some kind of step bars on since I bought the truck. I put GM fitted mud flaps on the truck when it was new and was concerned about clearence at the front wheel. I went with the powder coated black which looks great with the truck and fits fine with the GM fitted mud flaps. The oval design also looks great, big enough for a step but still close to the body for a clean look. Great price when compared to similar products. Best of all the installation. UPS dropped off at 5:30PM installation complete at 6:15PM using basic hand tools. Brackets clearly labeled, L/R and F/C/R. Instructions not great but anybody with a little ability will have no problems. Don't wait! Order yours today!" —Jeff I from Kansas City, MO bought an Aries 4" Oval Nerf Bars for a 2003 GMC Sierra, Heavy-duty, crew cab.
