I've installed several sets of leveling blocks like you showed...the u shaped spacer...much easier install than than the old style that went on top of the strut..I run 285s on stock wheels..first set of goodyears rub just a touch when turning in a dip...running nittos now and have no rubbing issues...but all the ones I've done are 4wd..
new 4wd parked next to a 2wd have very little height difference. ..you could do some measuring of both with stocks tires and get an idea of how much clearance to fender difference ..as long as both have same diameter tire..
