Upgrade the failure prone center cab mount on your six cylinder or V8 800. We very rarely see factory mounts that haven't failed or began to. Our mounts make the cheesy factory pieces look silly in comparison. They ship as a flat piece and are easily formed in a vice and welded together. Choose the assembled option if you'd like us to perform this step. These do require welding to install. Sold as a pair, buy one pair per truck.
