AMBULL 1/2" G80 Hammerlock Safety Chain Connector Links 2-Pack – 12,000 lb WLL, Black with Rubber Isolators

AMBULL 1/2" G80 hammerlock safety chain connector links are heavy-duty tow coupling links sold as a 2-pack, engineered to join safety chains and shackles with a 12,000 lb working load and a rugged corrosion-resistant finish.

These coupling links are built from Grade 80 alloy steel and finished in black to resist rust and abrasion. Each kit includes two coupling links with drive pins and four removable rubber isolators that reduce noise and wear during towing. The design lets the connector function as both a standard hammerlock link and as a D-ring style shackle, simplifying hookups for a wide range of vehicles and trailers.

How strong and durable are these AMBULL hammerlock coupling links?

The connectors are manufactured from G80 alloy steel for high tensile strength and improved wear resistance. They carry a working load limit of 12,000 lbs and a stated break strength up to 47,000 lbs, designed to stand up to heavy towing demands and frequent use.

• Material: Grade 80 alloy steel for higher strength-to-weight ratio
• Working load: 12,000 lbs per connector
• Break capacity: up to 47,000 lbs for safety margin in extreme loads
• Black protective finish for corrosion resistance

What do the rubber isolators do and why are they included?

Each connector comes with removable rubber isolators that cushion metal-to-metal contact, helping prevent abrasion and lowering vibration-induced noise during towing. The isolators also help the chain and vehicle attachment points last longer by reducing direct friction.

• Includes four removable rubber isolators for noise reduction
• Isolators limit wear where the link contacts the chain or vehicle
• Removable design allows use with or without isolation depending on task
• Rubber parts can be replaced if worn without replacing the whole link

Which vehicles and towing setups work with these connector links?

The 1/2" hammerlock coupling links are compatible with a broad roster of vehicles and towing gear — from farm equipment to recreational trailers. Their dual-purpose form works as a conventional coupling link or as a D-ring shackle for winch and tow applications.

• Fits tractors, forklifts, RVs, UTVs, trucks, trailers and SUVs
• Can double as a 1/2" D-ring shackle for winching and recovery
• Useful for both permanent towing setups and temporary recovery use
• Packaged components support quick installation and replacement

What comes in the package and what warranty support is offered?

Each purchase delivers a ready-to-use two-pack set with pins and isolators, packaged to protect the components in storage or transit. AMBULL backs the product with 12 months of support for manufacturing quality concerns so you can replace or repair if defects arise.

• Includes: 2 coupling links, 2 drive pins, and 4 detachable rubber isolators
• Secure packaging to prevent damage during shipping and storage
• 12-month manufacturer support for quality-related issues
• Simple assembly — pins secure with hammerlock action for quick hookups

Who is this for: These AMBULL hammerlock coupling links suit users who need reliable, heavy-duty connectors for towing, recovery, or rigging—operators of trailers, farm machinery, commercial trucks, off-road vehicles and anyone looking to replace worn shackles with a robust, versatile option. They are ideal when you want a compact, easy-to-install coupling with noise-reducing isolators and proven G80 strength for demanding conditions.
