The factory length safety chains are oftentimes not long enough to connect your trailer to your hitch receiver when utilizing a drop hitch. We have two solutions for this: One is to use the BulletProof Channel Shackles, they allow you to connect the safety chains to the hitch. The second is to replace the safety chains with longer BulletProof safety chains. Our safety chains will allow you to connect the trailer to your vehicles hitch receiver regardless of what size drop you have. *Sold as a pair of 2 chains* Medium Duty: 5/16” links, chain is 36” long with a 18,800 lb. capacity per pair.
