35" tires was always the accepted point of major mods.
Suspension is obvious, but gearing, axles, braking, and steering are often overlooked or not budgeted for.
Your 3.50 gears will certainly get you down the road, but it will be hard on clutches, and worst of all, driving won't be much fun.
Factory 28 spline axles weren't made to carry those big tires. Sure they'll get you down the road in a parade , but the jump to 35" or bigger will be the weak link when the going gets tough.
Your brakes will also see more leverage from taller tires. Even factory size discs should be reconsidered for tires that big.
Power steering. Is yours up to it? How about your tie rod set-up?
