{"product_id":"dana-60-grizzly-locker-30-spline","title":"Yukon Dana 60 Grizzly Locker - 30 Spline, 4.56 \u0026 Up Ratio","description":"\u003cp class=\"p1\"\u003eThe Yukon Dana 60 Grizzly Locker is a fully mechanical automatic locking differential designed to deliver maximum traction in demanding off-road, rock crawling, towing, racing, and heavy-duty applications. Unlike limited-slip differentials that divide torque between wheels, the Grizzly Locker provides 100% torque transfer to both axle shafts when engaged, helping maintain forward momentum in loose terrain, mud, rocks, snow, and other low-traction conditions.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eBuilt around a heavy-duty forged case and high-strength 8620 heat-treated internals, the Grizzly Locker is engineered to withstand severe shock loads generated by large tires, low-range gearing, high-horsepower engines, and aggressive driving conditions. Designed specifically for Dana 60 axles with 30 spline shafts and 4.56 \u0026amp; numerically higher gear ratios, this locker is an excellent upgrade for trail rigs, rock crawlers, competition vehicles, work trucks, and heavy-duty off-road builds.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003e\u003cb\u003eIncludes:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003eDana 60 Grizzly Locker assembly\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eInternal locking mechanism\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eFully assembled carrier unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary\u003e\u003cstrong\u003eSpecifications \u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\n          \u003cpath class=\"vertical\" d=\"M2.75 7H11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\n          \u003cpath class=\"horizontal\" d=\"M7 2.75L7 11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\n        \u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e Yukon Gear \u0026amp;
