Take your Unimog to the next level with the Unidan Overdrive Kit, engineered specifically for SBU models including the U1250, U1300, U1700, U1750, U2150, U2450, and more. This upgrade delivers smoother, quieter, and more fuel-efficient travel by reducing engine RPM at higher speeds—without sacrificing your vehicle’s renowned off-road performance.

How It Works

The Unidan Overdrive Kit seamlessly integrates into your drivetrain and is designed to split all gears. With a simple driver-operated clutch-in, switch-on, clutch-out process, you can engage or disengage overdrive even while driving—no air system required.
