Assembled Extreme Duty Dana 20 Output System w/ Speedo Parts SKU: 8280KITNET

Early Bronco Dana 20 Transfer Case Extreme Output System

Eliminate the weakest link in your Early Bronco’s drivetrain with the Extreme Output System for the Dana 20 transfer case. After 50+ years of abuse, the stock 10-spline output shaft is too small and weak for modern off-roading. This heavy-duty upgrade features a 32-spline shaft that’s 25% larger in diameter and at least 50% stronger than stock, making it the ultimate solution for preventing axle wrap failure on the trail.

• Stronger Than Stock – 32-spline design is at least 50% stronger than the factory 10-spline shaft

• Larger Diameter – This shaft is 25% larger than the stock output shaft for increased durability

• Fully Assembled Kit – Includes speedometer gear, housing, and cable for a quick, easy installation

• Bolt-In Upgrade – Can be installed in an afternoon with minimal modifications

• Helps Prevent Axle Wrap Failure – Strengthens your drivetrain for rugged off-road use

This unit is 1.3” longer than stock, so shortening the rear driveshaft may be necessary. Want a different yoke option? We offer 1310, 1350 NON-CV, 1350 CV, and 1350 CV Flanges—just give us a call!
