Divorced Atlas Transfer Case Guide

The Divorce Mounted Atlas Transfer Case has been created to give you all the great gearing options, parts availability and strength features to vehicles that require a remote-mounted transfer case. This documentation examines what divorced transfer cases are, when they should be used and what you will need to install one. Contact Advance Adapters if you have further questions about this design.

Married vs. Divorced Transfer Case

Most modern vehicles have a married transfer case housing that attaches directly to the transmission using an adapter; sometimes they are even integrated as a single unit. Conversely, divorced transfer cases are a separate part mounted independently further along the driveline. They are attached to the powertrain by a small driveshaft coming from the transmission.

Early vehicles sometimes ran this type of independent transfer case. In the present day, you’ll often see a divorced transfer case on vehicles with long wheelbases such as military trucks and commercial haulers. Using an independent transfer case also has benefits when customizing 4x4’s and off-road trucks. They allow greater access for future engine or transmission modifications and adjustments, and in some cases, they make it easier to leave the factory 4WD system intact.

Divorced Transfer Case Setup

This transfer case functions identically to others and has a front and rear driveshaft. The entire transfer case assembly is hung from the frame on a crossmember-type mount. The Divorced Atlas can be built as either a right or left drop unit. The shifters and crossmember are sold as a separate kit to fit the transfer case. When ordering yokes for this unit, three are required.

The mounting plate included in our kit will give you the rigid mounting location for supporting this gearbox against the frame. Prothane bushings and all hardware are included in this kit. It is necessary to fabricate a support bracket from our transfer case mount to the frame rails of your vehicle. Please be aware that this new mount bracket is very rigid and should be able to withstand the extreme twisting load that the gearing of the Atlas transfer case creates. Keep in mind that a good amount of frame flex may be generated in severe off-roading conditions.

Divorced Transfer Case Options

We only offer the divorced units in the two-speed configuration. The default adapter has a 32-spline input and needs three yokes with a C-bore, a case mount and a cable shifter.
