It is a chain-driven, planetary designed gear box with a low ratio of 2.72 to 1. For the average 4-wheeler, this is a good transfer case. One of the biggest faults of this transfer case is the overall length. At 20+ inches, this creates an extremely short rear driveshaft in the Jeep YJ \u0026amp; TJ Wranglers, which becomes even more crucial when the vehicle is lifted or a transmission swap is performed. In addition to a lift kit installation, larger tires are usually the next upgrade. Strength and driveline angle of the output shaft then becomes a concern. To make the NP231 better suited for these upgrades, we have designed our “Fixed Yoke” kit with the best features available. We manufacture a new one-piece tail housing that will add 3-1\/2” to 4” to your rear driveline length on a YJ, and up to 6” on a TJ. This will allow you to obtain a better driveshaft angle and eliminate driveline vibrations. We also manufacture a new 32 spline output shaft that is over 50% stronger than stock. This kit, along with a new 1310 series C.V. yoke, makes the NP231 a better transfer case for trail use. A full set of installation instructions is provided to assist in the installation of this kit.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"468\" width=\"468\" alt=\"\" src=\"https:\/\/www.advanceadapters.com\/images\/uploaded\/jeep\/tj%20rear%20sye%20not%20installed.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"419\" width=\"459\" alt=\"\" src=\"https:\/\/www.advanceadapters.com\/images\/uploaded\/jeep\/xj%20or%20yj%20measure%20pre-sye_1000.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"474\" width=\"474\" alt=\"\" src=\"https:\/\/www.advanceadapters.com\/images\/uploaded\/jeep\/tjrearwithsyemeasure_1000.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"482\" width=\"482\" alt=\"\" src=\"https:\/\/www.advanceadapters.com\/images\/uploaded\/jeep\/TJ_Rear_Double_Cardan_1_1000.jpeg\"\u003e\u003c\/p\u003e\n\u003cp\u003eClick \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0656\/9348\/3170\/files\/AA50-7906_SYE_Instructions.pdf?v=1759775517\"\u003eHERE\u003c\/a\u003e for installation instructions. \u003c\/p\u003e\n\u003ch3 class=\"station-tabs-tabtitle\"\u003e\u003cspan id=\"station-tabs-tab_ht-i0-t20\" class=\"station-tabs-tab mod-last is-active\" aria-controls=\"station-tabs-tabpanel_ht-i0-t20\" data-slug=\"vehicle-fitment\" role=\"button\" aria-expanded=\"true\" tabindex=\"0\"\u003e\u003cspan class=\"station-tabs-tabtext\"\u003e\u003cspan\u003eCA Residents: \u003c\/span\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0656\/9348\/3170\/files\/Screenshot_2025-10-21_164702.jpg?v=1761090683\" rel=\"noopener\" target=\"_blank\"\u003eProp 65 Warning\u003c\/a\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e","brand":"Advance Adapters","offers":[{"title":"Default Title","offer_id":45872359604386,"sku":"AA50-7906","price":258.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/9348\/3170\/files\/AA50-7906.jpg?v=1759774456"}],"url":"https:\/\/www.partsmike.com\/collections\/advance-adapters.oembed","provider":"Parts Mike, Inc.","version":"1.0","type":"link"}
