This may have been covered elsewhere. But I am having quoted some 20" (20x10) wheels (Fuel) with 35" tires to install on my crewcab 2019 F250 4x4. One retailer is telling me I may or may not need the leveling kit to keep the tires from rubbing, but if I do, then track bars are needed.. Another is quoting me the leveling kit but has said nothing about the need for track bars to keep the axle on center.
A few questions are:

• do I need a leveling kit to install 20x10 Rims with 35" Nitto tires?
• If I need a leveling kit, do I need Track Bars?
• Would there be any shortcuts that an installer would use to install the leveling kit but not use the track bars to keep the axles on center?

Thanks guys.
