Sold as a set of two 33\" chains in 5\/16\" diameter (other diameters available in the line), they balance strength and flexibility so you can meet Class IV trailer safety requirements without excess weight or bulk.\u003c\/p\u003e\n\n\u003ch3\u003eHow strong is this lifstar safety chain and what sizes are available?\u003c\/h3\u003e\n\n\u003cp\u003eThe breaking strength depends on the chain diameter: lifstar lists 7,600 lbs for the 3\/16\" equivalent, 11,700 lbs for the 5\/16\" model, and 16,200 lbs for the 3\/8\" version. These figures reflect the chain's tensile breaking capacity rather than its working load limit, which is typically lower for safe towing practices.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eThis listing: 5\/16\" diameter, 33\" length per chain, pack of 2, 11,700 lbs breaking strength\u003c\/li\u003e\n  \u003cli\u003eOther diameters in the product family: 3\/16\" (7,600 lbs) and 3\/8\" (16,200 lbs)\u003c\/li\u003e\n  \u003cli\u003eWelded links and heat-treated alloy steel for consistent tensile performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and use these chains safely?\u003c\/h3\u003e\n\n\u003cp\u003eConnect one end of each chain to the trailer frame and the other to the tow vehicle’s safety chain anchors using the provided hooks.

If you haul trailers, small equipment, ATVs, utility trailers, or campers and need a dependable, welded safety chain set that balances strength with manageable weight, the lifstar 5\/16\" x 33\" pair is a practical choice. It's aimed at owners who want quick-hook convenience, clear strength ratings, and durable construction for routine towing tasks. For heavier trailers or commercial uses, consider the larger 3\/8\" variant or consult a towing professional to confirm the correct chain diameter for your application.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is a 5\/16\" chain strong enough for my trailer?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The 5\/16\" lifstar chain has a breaking strength of 11,700 lbs; confirm your trailer's gross towing weight and manufacturer's recommended working load before use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long should safety chains be mounted?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Chains should allow safe turning without dragging; 33\" length is common, but adjust attachment points to avoid excessive slack or tightness.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"lifstar","offers":[{"title":"Default Title","offer_id":48084595769502,"sku":"B0CBNN6S41","price":38.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/lifstar-front-packaging-view.jpg?v=1785860423","url":"https:\/\/northtrailauto.ca\/products\/lifstar-heavy-duty-trailer-safety-chains-5-16-x-33-pack-of-2-welded-alloy-steel-11-700-lb-breaking-strength","provider":"North Trail Auto","version":"1.0","type":"link"}
