This is a Chromolly weld in bung for your link suspension, this is one of the big ones for your lower links or wishbone, for the area taking the most abuse. This one is cut in a race style where most of the rod end resides within the Bung & Tube. This is the left hand thread model. They are pretty straightforward in design and a fair priced, reliable choice of Tube Insert for your truck. They are sold individually but we can fit a ton of them in a flat rate envelope!
