This all-in-one kit replaces the internal pumping components that control pressure and return action, letting you revive a trusted workshop jack without buying a new unit. Materials and seal compounds are chosen to resist wear and repeated high-pressure cycles typical in automotive use.\n\n\u003ch3\u003eHow will this rebuild kit improve my jack's performance?\u003c\/h3\u003e\n\u003cp\u003eReplacing both the small and large low-side plungers together with fresh seals restores proper hydraulic pressure and smoother pumping action.

If you maintain a common brand jack like Pittsburgh, Big Red, Arcan, or a compatible Harbor Freight model and you notice leaks, reduced lift, or inconsistent pumping, this kit provides the internal parts needed for a cost-effective, professional-grade rebuild. Always verify the part dimensions and jack model compatibility before ordering to ensure a proper fit.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this kit fit my 3-ton Pittsburgh dual-pump jack?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Likely yes for many Pittsburgh dual-pump models—compare the supplied plunger and cylinder dimensions to your originals to confirm fit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special tools to install the rebuild kit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No special hydraulic tools required; basic hand tools and following the included steps are sufficient for most users.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Saillong","offers":[{"title":"Default Title","offer_id":48085931884702,"sku":"B0G1C61KMV","price":48.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/saillong-front-packaging_25163a6a-6205-4741-8989-cab362fdb08a.jpg?v=1785881106","url":"https:\/\/northtrailauto.ca\/products\/saillong-3-ton-dual-pump-floor-jack-rebuild-kit-large-small-plungers-with-17-piece-seal-kit","provider":"North Trail Auto","version":"1.0","type":"link"}
