Westin E-Series Step Bars are made of 3 inch diameter round tubing and are available in polished or black powder coat finish. Recessed step pads maintain the integrity of the step tube for maximum rust protection. Applications are vehicle specific and a mount kit is included, so there is only one part number to buy. Applications utilize factory mount points for installation for an easy no-drill installation and are backed by Westin lifetime warranty on polished stainless steel and by a 3 year warranty on black powder coated e-coated mild steel.
