DESCRIPTION
Product Overview
- The Hammerlock Coupling Links are forged from industrial-grade G80 alloy steel and rated at 47,000 lbs break strength — the same grade used in overhead lifting applications. The drive pin and locking sleeve system creates a permanent connection that won’t rattle loose or deform under load. Install with a hammer, and it’s mechanically locked — remove it later with a punch and hammer. This is a permanent safety connection, not a quick-disconnect.
- The vibrant red powder coat resists rust and makes the links easy to spot in your recovery bag or on your hitch. For anyone who tows heavy and takes safety chains seriously, these links are the upgrade your setup deserves.
Key Features
- Forged from G80 industrial-grade alloy steel — not cast metal, not mild steel. The same material grade specified for overhead lifting chains, rated for 47,000 lbs break strength with a 12,000 lb working load.
- The hammer-driven locking sleeve creates a connection that won’t loosen from vibration. Unlike threaded quick-links that can back out, the drive pin is mechanically locked — install with a hammer, remove with a punch and hammer. For safety chain connections where failure isn’t an option, a permanent lock is the professional standard.
- Electro-galvanized undercoat with a vibrant red powder coat top layer to resist rust from rain, mud, and road salt. Includes heavy-duty rubber isolators that eliminate metal-on-metal rattling and protect your vehicle’s finish. The bright color also makes the links easy to locate and visually confirm they’re connected.

FAQ
Q: How do I install a hammerlock coupling link?
A: Pass the two halves of the link through your safety chain and hitch loop, then mesh them together. Place the locking sleeve in the center slot between the aligned holes, insert the drive pin into one side, and hammer the pin through the sleeve until it is fully seated and mechanically locked.
Q: Can I use these as my primary safety chain connectors for towing?
A: Yes — this is their primary purpose. The 47,000 lbs break strength exceeds the requirements for safety chain connections on all standard trailer classes. Since safety chains should always be used in pairs, this 2-pack provides one permanent, heavy-duty connection for both your left and right safety chains.
Q: What’s the difference between a hammerlock link and a standard quick-link?
A: A standard quick-link uses a threaded sleeve that can loosen from vibration. A hammerlock uses a pressed-on locking sleeve that can’t back off — it requires tools to remove. For safety-critical connections where failure isn’t an option, hammerlock is the professional standard.
Q:Do I need to buy separate isolators to stop these links from rattling?
A: No! Our hammerlock links come with custom rubber isolators already included in the box. They fit snugly inside the links to completely eliminate metal-on-metal noise and protect your bumper's paint from scratches.
Q: Need shackles, chains, or a hitch receiver for your towing setup?
A: Pair these links with our 3/4" D-ring shackles for additional recovery connection points. For your hitch, add a 70,000 lbs D-ring hitch receiver or a 5/8" anti-theft hitch lock.

Verified buyerRunning between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Chris D.
Verified buyerGot four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.
Travis M.
Verified buyerTowing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.
Mike R.
Verified buyerHauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.
Jason T.
Verified buyerUsed to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.
Brandon L.
Verified buyerBought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Fitment guaranteed or refundGot questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
