I am planing on getting 305/75/16's on my truck. or some 285's. But if i crank my torsion bars. What should i do for the rear? add a bigger lift block? I have a 1998 Lariat extended Cab with a 4.6L 4x4.

 

You will have to do nothing to the rear, just get an alignment after cranking them. I think you might even get away with not doing it at all, at least with the 285's.

 

You probably won't get enough lift out of the front to make the truck bulldog. If you want/need the rear taller, just replace the oem 2 inch lift block with a taller one.

 

with 285's you dont need to do anything, unless u have a stepside like me then theyll hit the mudflaps which i dont think it is a big deal and i kinda having them, less roadspray, (any of yall think theyll make the tires wear faster i dont think so cause its just plastic?) with 305s and the torsion bars cranked youll have a little more clearance and if they rub at all it will be very minimal (so im told correct me if im wrong) and the rear should be fine

 

go w/ 285s and 16x8 or 16x10 aftermarket rims. its what i have
