If you have an ’05-up Ford Super Duty and you want to ditch the 6.0L or 6.4L Power Stroke for the Cummins 5.9L Six, Ford Cummins offers a repower kit that can make it happen.

Tip:

When using the 4x4's brakes hard, your vehicle’s front suspension compresses and you ‘use up’ most of its suspension travel. When braking heavily to avoid an obstacle e.g. pot hole or rut, and you cannot stop in time, release the brake pedal just prior to hitting the obstacle. This will allow the front suspension to return to its normal height and give more suspension travel when hitting the obstacle.
