AMBULL 2-Pack 1/2" G80 Hammerlock Tow Chain Connector Links — Red, 12,000 lb Rated with Rubber Isolators

The AMBULL 2-pack 1/2" G80 hammerlock coupling links are heavy-duty tow chain connectors built for secure, low-noise towing with a 12,000 lb working load and upgraded rubber isolators.

These coupling links are engineered from grade 80 alloy steel to resist corrosion and wear in demanding conditions. Each set arrives ready to install: two hammerlock links, drive pins, extra connecting links and four detachable rubber isolators that help protect vehicle surfaces and reduce vibration and clatter during use. The bright red finish improves visibility, and the design accepts standard 1/2" chains and D-ring shackles, making the connectors a versatile addition to your towing or recovery kit.

How strong and durable are these coupling links?

The AMBULL hammerlock links use G80 alloy steel for a high strength-to-weight ratio and improved toughness compared with mild steel. They are rated for a 12,000 lb working load with a 47,000 lb minimum breaking strength, suitable for heavy towing tasks when used according to industry standards.

• Grade 80 alloy steel construction for increased durability
• 12,000 lb rated working load for common towing needs
• 47,000 lb minimum breaking strength for safety margin

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

Each connector comes with detachable rubber isolators that cushion metal-to-metal contact, limiting abrasion on the connector and the vehicle attachment point. The isolators also dampen impact noise and vibration during towing or recovery, making the assembly quieter and less likely to damage painted surfaces.

• Four removable isolators included per 2-pack set
• Reduce wear between chain, link, and vehicle fittings
• Lower operational noise and vibration when towing
• Easy to replace or remove for cleaning or inspection
