Marlin Crawler Dual Transfer Case Adapter


SKU: N/A Categories: ,

Product Description


Installing a dual transfer case into a 4-cyl equipped truck requires moving your existing t/case back approximately 6.5 inches. The additional “Crawl Box” is installed between your transmission and t/case. All 4-cyl gear driven t/cases are 21-spline except for the 1986-87 turbo, which is 23-spline. 2.28:1 or 4.70:1 gears can be used in any combination in the two t/cases. The most common choice is one set of 2.28:1 gears and one set of 4.70:1 gears, known as a Dual Ultimate™ Crawler. When building a transfer case for 4-cyl applications, the stock 21-spline input gear can be used. When building turbo, V6 & V8 applications, we highly recommend using a larger 23-spline input in the rear t/case. Otherwise, failure of a factory 21-spline input gear is certain. Floorboard and drive shaft modifications are required. The factory crossmember remains in its original position.
