Lift it right. Wheel it right.
An off-road and lift guide to the 1999-present Ford Super Duty, generation by generation: front suspension, lift options and their tradeoffs, death wobble, Tremor notes, towing with a lift, tire fitment and Power Stroke pointers. Every fact has at least two sources.
The guide
Death wobble on a Super Duty?
Ford published bulletins and a damper program for some trucks. But track bars, worn ends, caster and tire pressure are causes too. Here is what to check, in order.
Three rules for lifting a Super Duty
1. Fix the caster
Taller lifts need geometry correction, not just height.
2. Ratings don't grow
A lift doesn't raise tow or payload ratings. Level the trailer with a drop hitch.
3. Load-rated tires
Bigger tires must still carry the truck. Recalibrate the speedometer.
