Special Considerations

• Potential Modification of Driveshafts and Crossmember: Depending on your application, you may need to adjust the lengths of your driveshafts and/or modify the crossmember to fit in your vehicle. 

• Possible Body Lift Requirement: Based on the application you are installing your new Atlas transfer case in, you may need to add a body lift for proper clearance.

• CV Yoke Selection: Use our chart below for help identifying which CV Yoke series your vehicle should have. However, please double-check your vehicle to ensure you order the correct yokes as many rigs have been modified or upgraded over the years.

Early Bronco Specific Notes (1966–77 Ford Bronco)

If you're installing the Atlas 2 in a classic Early Bronco, keep these key details in mind:

• Fitment Adjustments: The Atlas is about 2.5" longer than the factory Dana 20, requiring rear driveline shortening and potentially front driveline lengthening. A body lift helps—but isn't required (tight fit).

• Shifter Kit Options: Standard configuration includes a twin-stick shifter for '66–77 Broncos. A cable-operated shifter upgrade is also available.

• C6 Conversion Caveat: If your C6 output shaft was cut to adapt to a Dana 20 input shaft, it won’t be compatible with the Atlas 2.

• Adapter Compatibility: Will not bolt to the stock 3-speed Bronco adapter or NP 435 with a converted 3-speed adapter. Contact us for proper conversion support.

Available Speedometer Connection Kits

• Stock Speedometer (No EFI): Direct-connect cable to stock Bronco speedo.

• Stock Speedometer with EFI: Kit includes pulse sensor, coupler, drive pin, and cable.

• Digital Speedometer Kit: Includes cable, coupler, and drive pin for use with existing VSS sensor.

CV YOKE FITMENT INFORMATION

CV Yoke Fitment Information: The CV yoke fitment details below are based on commonly available data. Because many vehicles have been modified or upgraded over the years, we strongly recommend verifying your vehicle’s current yoke configuration before ordering to ensure proper selection. The CV joint series can vary based on specific configurations, such as engine type, transmission, and any aftermarket modifications. For precise identification, it's recommended to measure the existing U-joints or consult the vehicle's service manual.
