Extreme Duty Dana 20 Transfer Case Output System, 66-77 Ford Bronco SKU: 8272

Early Bronco Dana 20 Transfer Case Extreme Output System

One of the biggest weak links in your Early Bronco’s drivetrain is the stock Dana 20 output shaft. After years of wear, heat cycling, and hard trail abuse, that original 10-spline shaft just can’t keep up with the demands of modern builds running big tires and serious power. That’s where the Extreme Dana 20 Transfer Case Output System comes in.

This upgrade replaces the factory shaft with a massive 32-spline, 25% larger diameter output shaft—delivering a strength increase of over 50% compared to stock. All components are designed to fit inside the factory Dana 20 housing, with no modifications required. Installation is straightforward and can be completed in a single afternoon with basic tools.

• Major Strength Upgrade: 32-spline output shaft is 25% larger and 50% stronger than stock

• Factory Housing Fitment: Drops into the stock Dana 20 housing with no modifications needed

• Simple Installation: Can be installed in one afternoon—detailed instructions included

• Minimal Driveshaft Impact: Output is ¾" longer than stock—may require driveshaft adjustment in rare cases

• Includes CV Yoke: Comes with 1310 CV yoke (other yoke options available—see #8280 for assembled system)

• Trail-Tested Durability: Ideal for rigs running larger tires, upgraded axles, and more torque

Stop worrying about your Early Bronco Dana 20 transfer case output shaft and hit the trail hard with the Extreme Output Kit - a rock-solid upgrade for your rig.
