IMPORTANT - When ordering differentials you must know very specific things about your vehicle and/or axle.  Many vehicles come with optional axles ... example, Jeep Cherokees may have Chrysler rear axles or Dana rear axles, and Jeep Wranglers may have Dana 35 rear axles or Dana 44 rear axles.  The possibilities are practically endless.  If you are not absolutely sure which differential to order, call or email us or ARB.  Returns due to ordering the wrong differential will be subject to restocking fees.
