N-FAB RKR Rails are perfect for the off-road enthusiast. They are constructed using a .120" wall and 1.75" tubular steel. Then they are treated inside and outside to resist rust and corrosion. The RKR Rails are fully welded to provide maximum strength. The RKR Rails have optional drop-down steps that are sold separately in pairs if you want a unique look while giving you a more helpful step up.
