{"product_id":"power-tank-monster-valve-flat2-high-flow-valve-stem-for-kmc-beadlock-w","title":"Power Tank Monster Valve Flat2 High-Flow Valve Stem for KMC Beadlock Wheels","description":"\u003cp class=\"product-lead\"\u003eThe Power Tank Monster Valve Flat2 is a single oversized, high-flow aluminum valve stem designed to install as a second stem in KMC Beadlock wheels with dual valve stem ports, enabling dramatically faster tire deflation and inflation than a standard Schrader valve. At 1.1 oz per valve and 5 times the stiffness of a standard metal valve stem, the Flat2 adds speed without adding meaningful weight or requiring tire rebalancing after installation. This listing is a single spare valve and does not include the Monster Key installation tool or a Monster Chuck.\u003c\/p\u003e\n\n\u003ch2\u003eFaster Air-Down, Faster Air-Up\u003c\/h2\u003e\n\u003cp\u003eThe Monster Valve Flat2's oversized bore moves air at a rate that a standard Schrader valve cannot match. A 40x13.5x17-inch tire airs down from 35 psi to 10 psi in under 30 seconds. When paired with a Power Tank CO2 system and Monster Chuck (each sold separately), that same tire can be reinflated in 50 to 60 seconds. For overlanders who air down and back up at every trail head, that time savings adds up across a full day of driving.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Last Without Rebalancing\u003c\/h2\u003e\n\u003cp\u003eThe Monster Valve Flat2 is machined from 7018 aluminum with an aluminum collar and aluminum dust cap, keeping each valve to 1.1 oz, light enough that no tire rebalancing is needed after installation. The aluminum construction is 5 times stiffer than a standard metal valve stem, resisting the flex and fatigue that can cause conventional stems to leak or fail under repeated airing cycles. A lifetime warranty covers the valve, and every Monster Valve is designed to be fully rebuildable.\u003c\/p\u003e\n\n\u003ch2\u003eDesigned for KMC Beadlock Dual-Valve Wheels\u003c\/h2\u003e\n\u003cp\u003eThe Flat2 mounts in the second valve stem port found on KMC Beadlock wheels, leaving the original Schrader stem in place, so any factory TPMS sensor stays on the existing stem and continues to function. Installation requires removing the tire from the wheel first; the Monster Key installation tool (sold separately) is required for a complete install. Owners of KMC Grenade wheels need one additional Long Stem and one 12mm Spacer per valve (both sold separately) for proper fitment.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7018 Aluminum Body:\u003c\/strong\u003e oversized bore for high-flow air-down and air-up\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAluminum Collar and Dust Cap:\u003c\/strong\u003e full aluminum construction at 1.1 oz per valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo Rebalancing Required:\u003c\/strong\u003e light enough that tire balance is unaffected after installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5x Stiffer Than Standard Metal Valve:\u003c\/strong\u003e resists flex and fatigue through repeated airing cycles\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTPMS Compatible:\u003c\/strong\u003e installs as a second stem, leaving the factory TPMS sensor on the original Schrader valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime Warranty:\u003c\/strong\u003e fully rebuildable design backed by Power Tank's lifetime service\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003e7018 Aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCollar Material\u003c\/td\u003e\n      \u003ctd\u003eAluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDust Cap Material\u003c\/td\u003e\n      \u003ctd\u003eAluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight Per Valve\u003c\/td\u003e\n      \u003ctd\u003e1.1 oz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWheel Compatibility\u003c\/td\u003e\n      \u003ctd\u003eKMC Beadlock wheels with dual valve stem ports\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eKMC Grenade Additional Parts\u003c\/td\u003e\n      \u003ctd\u003eLong Stem + 12mm Spacer required per valve (sold separately)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWarranty\u003c\/td\u003e\n      \u003ctd\u003eLifetime (void if used with balancing beads)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eMON-8620\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Monster Valve Flat2 suits overlanders and off-road drivers running KMC Beadlock wheels with dual valve stem ports who want the fastest possible air-down and air-up times at the trail head. It is also the right choice as a spare or replacement for anyone who already owns Monster Valve Flat2 stems and needs an additional single unit.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe Flat2 does not fit wheels without a second valve stem port, and it is not a complete installation kit: the Monster Key tool and Monster Chuck are not included and must be purchased separately. KMC Grenade wheel owners require an additional Long Stem and 12mm Spacer per valve, also sold separately. The warranty is void if the valve is used with balancing beads.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhich wheels does the Monster Valve Flat2 fit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Monster Valve Flat2 is designed for KMC Beadlock wheels that have a second, dual valve stem port. It does not fit standard single-port wheels. Owners of KMC Grenade wheels need one additional Long Stem and one 12mm Spacer per Monster Valve Flat2 for proper fitment; both are sold separately. Power Tank offers a Monster Valve Fit Kit to test compatibility before committing to a full set.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is included with this single valve, and what is not?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThis listing contains one Monster Valve Flat2 stem, a spare or additional unit. The Monster Key installation tool and the Monster Chuck air chuck are not included and must be purchased separately. A complete first-time installation also requires removing the tire from the wheel before fitting the valve stem.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow fast does the Monster Valve Flat2 air down a tire?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Monster Valve Flat2 can air down a 40x13.5x17-inch tire from 35 psi to 10 psi in under 30 seconds. When a Monster Chuck and a Power Tank CO2 system (both sold separately) are used to reinflate, that same tire can be brought back up in 50 to 60 seconds. These figures come from Power Tank's own product data for this valve.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the Monster Valve Flat2 work with factory TPMS sensors?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Because the Flat2 installs as a second valve stem alongside the existing Schrader stem, the factory TPMS sensor remains on the original stem and continues to function normally. No TPMS relocation or replacement is required for a dual-stem installation on a compatible KMC Beadlock wheel.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes installing the Monster Valve Flat2 require tire rebalancing?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo rebalancing is required. Each Monster Valve Flat2 weighs 1.1 oz, light enough that it does not affect tire balance after installation. Note that the warranty is void if the valve is used alongside balancing beads.\u003c\/p\u003e","brand":"Power Tank","offers":[{"title":"Default Title","offer_id":50621707321414,"sku":"MON-8620","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/MV_2_HERO.jpg?v=1791937139","url":"https:\/\/terrainvault.com\/products\/power-tank-monster-valve-flat2-high-flow-valve-stem-for-kmc-beadlock-w","provider":"TerrainVault","version":"1.0","type":"link"}
