Aries stainless steel 4” bull bars are made with 304 stainless steel, meaning they are high in nickel content to be truly rust-resistant. They easily withstand the wear and tear of the outdoor elements and add a flash of highlight to your vehicle with their mirror-like polished finish. Aries also offers an aluminum 4” bull bar from our Alumalite series. The aluminum bull bar is constructed from hardened T6 aluminum, making it very lightweight yet incredibly strong, and it is covered in a textured black powder coat finish for superior resistance to scratching, chipping and peeling. Our third finish option is a high-strength carbon steel bull bar covered in a textured black powder coat finish. All three bull bars are made with heavy-wall tubing and designed to complement our Big Step 4" round side bars.
