After reading many posting on here I either haven't found any issues or have not found the posting about leveling and warranties issues. With that being said, I'm considering leveling my 350 that's only a couple of months old with a
Ready Lift stage II 2.5".
So have you guys had any issues with warranties after leveling?

 

No. My dealer will even do this if I had included it in the sale.

No if you have problems with death wobble, steering, basic front suspension, I wouldn't expect Ford to cover that if I had messed with the front suspension components. But should not affect Engine, tranny emission type of warranty at all


I will say it affected my towing and I had to put some air bags on the rear to help when I tow.

 

As soon as you raise the front of the truck, you are introducing negative caster.
I have found that many of my lifted trucks required at least +1 of positive caster beyond what the factory did to compensate for a lift and larger tires.
Negative caster leads to wobbles.
