Nerf bar

A nerf bar is a tubular device fitted to the side of a racecar, typically single-seat race cars that compete on asphalt or dirt oval tracks.

A more commercial application of the nerf bar is for convenience purposes on a pickup truck or sport utility vehicle.

Some model specific brackets for nerf bars do not require drilling and use existing mounting holes in the frame of a vehicle.

Typically if they are being used to slide over rocks and past trees they are built with thicker tubing and attached directly to the truck's frame rails rather than the body.

[citation needed] The hot rod world will sometimes use a much smaller version of a racing nerf bar.
