Signature Series Step Bars All step bars are not created equal, as any professional installer will confirm! Westin controls every step of the manufacturing process with in-house cutting, bending stamping, polishing, state-of-the-art chrome plating and electrostatic powder coating. But long before the manufacturing begins, Westin engineers go to great lengths to utilize existing holes in the vehicle’s frame for maximum strength and easy no-drill installation. And, Westin’s custom-fit cartons eliminate freight damage, ensuring that the bars arrive in perfect shape.
