These nerf bars are 100% bolt on, no cutting or welding to your frame. These are not held on by weak 6mm bolts like other nerf bars. These are bolted directly to the frame with 5/16 grade 8 hardware. One factory 6mm bolt is used for attaching bars to rear fender support. Nerf bars are made of 1.75" x .120 wall tubing and designed for best protection. Kits come with one set of nerf bars, mounting brackets, hardware and directions. Nerf bars come uncoated. "These bars do not come with filler plate in triangle like pictured" Free Shipping to the lower 48 states, please contact me for shipping quote elsewhere.
