{"product_id":"np241-rock-trac-4-1-transfer-case","title":"NP241 Rock-Trac 4:1 Transfer Case","description":"The Zumbrota Drivetrain RTC241J-6 is a remanufactured NP241 transfer case specifically built for 2007-2018 Jeep JK models equipped with a manual transmission. This unit boasts a 4:1 low-range ratio and features the Rock-Trac option for enhanced off-road capability.\n\nCrafted with meticulous attention to detail, Zumbrota Drivetrain transfer cases are rebuilt to high standards. The remanufacturing process involves thorough inspection of cases and internal components for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. A Hydro-blast rinse and blasting procedure is used on all parts, followed by a proprietary deep cleaning. Each unit is fully rebuilt with the replacement of all bearings, seals, and viscous couplers. Rigorous spun testing ensures proper shift-ability and quiet operation before shipment, with units protected in high-density plastic totes.\n\nKey specifications include a 23-spline input shaft with a 0.84-inch exposed length, a bolt-on rear output yoke, and provision for a speed sensor. The 4:1 ratio offers significant gear reduction for crawling.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870928892216,"sku":"RTC241J-6","price":3953.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/np241-rock-trac-4-1-transfer-case","provider":"MOTORMIA","version":"1.0","type":"link"}
