I never understood the appeal of the ARB bumper. It's very big and very heavy and very obtrusive, both physically and aesthetically. Some people are into that.
The ARB front bumper protects the fenders and allows better approach angles than stock positioned bumpers. ARB stuff is designed for true Roo protection which makes them heavy but hell for stout. They also require surgery to use with Anti-Rock sway bar. Would've bought one if it wasn't for the weight and surgery required.
