Description

Got a big truck and have trouble getting in? Then a set of Boss nerf bars from Putco are the perfect solution. Boss nerf bars are the biggest and baddest looking side steps available.

Putco uses only the best 304 stainless steel tubing for their Boss nerfs. Each tube has a massive 4" diameter, giving you a beefy look and large step area. The step pads have a non-slip surface for secure entry and exit. Putco also includes vehicle specific brackets that make mounting a breeze.

Boss nerf bars have a mirror polished finish and are backed by Putco's NeveRust guarantee, so you know they will look great for years. Other brands may make 4" nerf bars for your truck but if you want the best, Boss bars are the only way to go. Made by Putco.
