Thinking of installing a lift on my 98 F150,4.6, 4x4, reg cab, long bed. I'm thinking of the Fabtech 6 inch lift with maybe 35 inch tires and no body lift! What size rims to get and with what back spacing? What do you guys recomend? Whith Suspension Kit to get? And what should I change my gears too? Any help on this? Also, why do some 4 inch lift kits look larger then 6 inch lifts?
