Each jack telescopes from 21.4\" to 40\" travel (19\" working range) and uses a triangular threaded screw with an M18 nut for secure, incremental adjustments. The zinc powder coat provides corrosion resistance for seasonal exposure, while the U‑shaped top fits most slide‑out frame rails.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these jacks stop slide‑out movement?\u003c\/h3\u003e\n\u003cp\u003eThe jacks work by bearing pressure under the slide‑out frame so the mechanism doesn’t bear all movement. Tightening the screw transfers lateral forces into the jack and ground, significantly reducing bounce and vibration when people move inside.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect vertical support under the slide‑out frame to limit flexing.\u003c\/li\u003e\n  \u003cli\u003eTriangular threaded screw and M18 nut for fine adjustments and secure locking.\u003c\/li\u003e\n  \u003cli\u003eSuggested use of a 2x4 on top to spread load and protect the trailer rail.\u003c\/li\u003e\n  \u003cli\u003eDesigned for parked stabilization, not for lifting a trailer off its wheels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the size and capacity details I should check?\u003c\/h3\u003e\n\u003cp\u003eEach stabilizer jack travels from 21.4\" to 40\", with a safe working range of about 19\" and a maximum lift capacity of 5,000 lb (2,267 kg) per jack.

They’re ideal if you want durable, adjustable support that’s easy to fit beneath most slide rails, resists rust for seasonal storage, and gives solid backing during occupancy. Note: purchase includes two quick‑lift jacks; always follow manufacturer safety guidance and never use these jacks as the primary method to lift or level a trailer.\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: Can these jacks lift my trailer off its wheels?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. They are designed to stabilize a slide‑out and prevent rocking, not to lift or support the trailer off its wheels.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these fit all slide‑out frames?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They fit most frames using the 5.94\"x2.95\"x0.9\" U‑top; use a 2x4 if needed and confirm clearance before use.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"LUSHIH","offers":[{"title":"Default Title","offer_id":48080976969886,"sku":"B0BM5GLBYV","price":79.85,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/lushih-front-packaging-and-jacks.jpg?v=1785793526","url":"https:\/\/northtrailauto.ca\/products\/lushih-rv-slide-out-stabilizer-jacks-2-pack-21-4-40-telescoping-5-000-lb-each","provider":"North Trail Auto","version":"1.0","type":"link"}
