I don't want to start a debate. But from what Mike and I talked about over the phone today is that the ARB is much better for a low impact collision. The accordion mounts will absorb the impact and lessen the force transmitted into the cab/occupants, as well as reduce the amount of force that goes into the frame, this may destroy the mounts, but better than a tweaked frame IMHO. The Slee is a solid mount which means all the energy transmitted into the bumper will go straight to the frame and make a much more rigid impact, a 45* impact at low speed will transmit into the frame and possibly bend the front frame horns (debatable, but PM if you think differently, let's not de-rail this thread). This is regarding hitting a concrete/brick wall at low speed. The Slee bumper has many, many, many advantages over the ARB and vise versa. I would contact your Insurance company and ask about their policies on non airbag compliant bumpers. My buddy had a custom plate bumper on his JK Rubicon and ran into the back of somebody and the air bag didn't deploy in time. Injuring his passenger and himself. The claim was quite high (both totaled) and the insurance said he was on his own for repair and compensation. I don't remember the insurance company . It's the same concept with tinted windshields. If you rear end somebody with dark windshield tint they can get you for applying a "hinderance to night vision" and say your on your own. I have checked with mine and have a medical permit for that reason. The ARB has a huge overhang, but it's a very stout bumper. I would rather get hung up on it while playing on the rocks than sacrificing frontal protection. Especially in the area where I live with a lot of drivers pulling out in front of you and daily stop and go traffic where accidents are very common. Rear end collisions happen quite a bit on the roads of Atlanta, I don't want to risk having that happen and disabling my truck. I'll keep the protection at the cost of offroad capability. If you can place the ARB properly on obstacles you won't have many issues. I don't care if it's certified for anything on the rear, as for the front...DOT/SRS compilable for me
