{"product_id":"np231-transfer-case-8","title":"NP231 Transfer Case","description":"The Zumbrota Drivetrain NP231 Transfer Case, model RTC231J-11, is a fully remanufactured unit meticulously rebuilt to exacting standards. Designed as a direct-fit replacement for 1997–2002 Jeep Wrangler TJ and 1994-2000 Jeep Cherokee (XJ) models, this transfer case ensures reliable performance and longevity.\n\nThis NP231 T-CASE features a 21-spline input shaft with a 0.75-inch exposed length, and a bolt-on front output yoke. The rear output shaft is equipped with 27 exposed splines and a protective rubber boot. It also includes a 2-pin shift indicator switch located above the shift lever. The remanufacturing process involves thorough inspection of all components for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. Zumbrota Drivetrain utilizes an exclusive Hydro-blast rinse and blasting procedure, followed by a proprietary cleaning process. All internal and external parts are meticulously cleaned to restore them to an OEM finish.\n\nDuring the rebuild, all bearings, seals, and viscous couplers are replaced with new components. Each finished unit undergoes rigorous spun testing to verify shift-ability and ensure quiet operation. To prevent damage during transit, all transfer cases are shipped in high-density plastic totes. This specific unit is identified by Hollander Numbers 412-348 and Tag Numbers 52098471, 52099310, 52099310AB, 52099364, 52099364AB, and 52099364AE.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870927843640,"sku":"RTC231J-11","price":3335.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/np231-transfer-case-8","provider":"MOTORMIA","version":"1.0","type":"link"}
