Truck Steps: Nerf Bars & Side Steps

Nerf bars, side steps and step bars — N-Fab, Lund, Carr and more, in oval, round and rectangular sections, powder-coated steel, stainless and aluminum.

A nerf bar sits tighter to the body than a running board, which is what you want on a lifted truck or anything that sees a trail: less to catch on a rock or a snowbank, and a smaller target for the shin on the way in. The trade is a smaller stepping surface, which matters more with passengers, in winter boots, or on a crew cab where a rear passenger is stepping too.

Check cab length and mounting before ordering. Cab-length bars stop at the cab; wheel-to-wheel run the length of the bed and double as a step to the box. Most bars bolt to existing body-mount holes, but a lift changes the geometry between the rocker and the ground — measure it rather than assuming.

Many listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.

Full-length or short step? Our running board guide weighs access against ground clearance, and what winter does to each.
