These are the under rail link bars we run on most of the Chevy/GMC trucks. They are great for running up to 12 inch wide wheels on most 1/2 ton trucks. The are constructed from 2x2 square tubing with a 1/4 wall thickness. The bungs are built from 2 inch .250 wall DOM tubing so they are very stout. The Link bars are sold in a pair and come with the polyurethane bushings and inner sleeves.
