Re: tire size
General concensus is that any higher than the RK kit, without using a proper lift kit, can cause severe damage to the upper ball joints. So unless it's only going to be a mall crawler, not a good idea. 33" will fit if you go with the coil spacer, but you'll need a 1.25" wheel spacer to keep the tire out of the upper ball joint. you'll need to do the "pinch weld mod" for clearance.
