Pro-Am's nerf bars bolt up directly to the frame, providing a much stronger assembly, while eliminating the need for U-bolts. They provide maximum coverage for added safety and better aesthetics. We use 1-1/4" aluminum tubing for maximum strength and the Heavy-duty triple-hook net mounts and nylon netting ensures the longevity and strength. These Nerf Bars work with stock pegs or the Pro Armor PowerGRIP system.
