A 4\u2033 square jack advertised as 12K, 15K, 20K, or 25K is quoting its support rating. Its lift rating is a lower number.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\">Your gearbox has its own lift rating too, and whichever is lower becomes your real working limit. This Dual Speed model fits any standard 4\u2033 square jack and <em><strong>lifts<\/strong><\/em> up to <strong>8,000 lb. of tongue weight<\/strong>.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>Two Speeds, Simple To Use<\/strong><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\">The gearbox is marked <strong>LIGHT LOAD<\/strong> and <strong>HEAVY LOAD<\/strong>. The simplest way to think about it:<\/p>\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\" dir=\"ltr\">\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>LIGHT LOAD (3:1 high speed)<\/strong> \u2014 running the landing gear down to the ground, and back up to fully retracted. Travel only, no lifting.<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>HEAVY LOAD (11:1 low speed)<\/strong> \u2014 all actual lifting of trailer weight, whether the trailer is empty or loaded.<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\">High speed covers the distance. Low speed does the work.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>Choosing Between Models<\/strong><\/p>\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\" dir=\"ltr\">\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Lifting empty or light?<\/strong> Either Multi-Mount Trailer Gearbox handles it. Both are rated 8,000 lb. at 11:1. The Dual Speed adds the 3:1 travel mode for faster setup and retraction.<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Lifting loaded and heavy?<\/strong> Step up to the <strong>SuperMax<\/strong> \u2014 14:1 reduction, 10,000 lb. capacity.
