Designed for 1974 to 1979 Jeep full size vehicles equipped with the Borg Warner 1339 transfer case, this kit eliminates constant front axle engagement while preserving the strength and durability of the original drivetrain. Factory Quadratrac systems operate in full-time mode, keeping the front drivetrain engaged at all times, increasing wear and reducing fuel efficiency.\u003c\/p\u003e\n\u003cp\u003eThis conversion kit reconfigures the transfer case to allow true part-time operation when paired with included Mile Marker 104 Premium manual locking hubs, giving drivers full control over front axle engagement. By disengaging the front drivetrain during normal driving, the system reduces parasitic drag, decreases component wear, and can improve fuel economy while maintaining full off-road capability when engaged. Engineered with precision-machined components and backed by decades of drivetrain expertise, this kit provides professional installers and restoration builders with a proven modernization solution for classic Jeep applications.\u003c\/p\u003e\n\u003cp\u003eBuilt for durability, efficiency, and long-term reliability, Mile Marker restores control to the Quadratrac system without compromising performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures and Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConverts Quadratrac full-time system to true part-time operation.\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for 1974 to 1979 Jeep full size Quadratrac vehicles.\u003c\/li\u003e\n\u003cli\u003eIncludes Mile Marker 104 Premium manual locking hubs.\u003c\/li\u003e\n\u003cli\u003eReduces drivetrain wear and parasitic drag.\u003c\/li\u003e\n\u003cli\u003eUses original stock transfer case chain.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAssociated Comments:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned to work with 1974 to 1979 Jeep full size vehicles equipped with Borg Warner 1339 Quadratrac transfer cases\u003c\/li\u003e\n\u003cli\u003eConverts factory full-time systems to part-time operation while using the stock transfer case chain\u003c\/li\u003e\n\u003cli\u003eIncludes Mile Marker 104 Premium manual locking hubs\u003c\/li\u003e\n\u003cli\u003eVerify transfer case model and axle configuration prior to installation.\u003c\/li\u003e\n\u003cli\u003eEngineered specifically for Borg Warner 1339 Quadratrac applications only\u003c\/li\u003e\n\u003cli\u003eRequires proper installation procedures during transfer case disassembly and hub installation to ensure correct operation\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended to maintain drivetrain integrity and long-term performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSeries: Premium Series\u003c\/li\u003e\n\u003cli\u003eMaterial: Combination\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 Year\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Quadratec","offers":[{"title":"Material: Combination \/ Series: Premium Series \/ Sold As: Kit","offer_id":49224875639011,"sku":"95-12204-BCBT","price":786.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4343\/1651\/files\/95-12204-BCBT.jpg?v=1781034447","url":"https:\/\/shop.blackflagoffroad.com\/products\/mile-marker-borg-warner-1339-quadratrac-4x2-conversion-kit-with-104-hubs-mile-marker-95-12204-bcbt","provider":"Black Flag Off-Road","version":"1.0","type":"link"}
