Beaded welting that fits between the frame and running boards. Pre-cut and ready to install. Designed to match the originals and eliminate metal-to-metal road squeaks while protecting the paint from fender-to-body seam chips, easy to install. Each includes top quality, original style materials, each pre-cut, pre-punched and notched for a factory-style look and fit. These kits are well worth using just for their time-saving installation features.
