4 inch lift
Putting a lift in a 2013 Jeep Wrangler and using 33 inch tires depends on what size tires you are using now. You can get 33 inch tires to fit any size rim. If the Jeep is already lifted you may not need anything else but tires. A 2003 Jeep Wrangler, Rubicon Edition, has a 2 inch suspension and uses 33 inch tires.
You will need a minimum 3" lift to have 33" tires clear when making tight turns. 31" tires will fit with not modifications.
A few variables come into play (wheel width, wheel offset, tire width), but the general rule for the Wrangler YJ is... 1 inch of lift to fit 31-inch tires 2 inches of lift to fit 32-inch tires 3 inches of lift to fit 33-inch tires
at least 2 inches for 97-05 but you may need a 1"body lift or a full three inches
No, that's all the bigger you will want to go with out at least putting some body spacers or a suspension lift on it.
None.
at least 2"
4.56-4.88
you will need a lift kit ..
35" Tires will require a 6" suspension lift to clear with no rubbing. A cheaper alternative is a 3" body lift, and 33" tires, although not as appealing.
A 2 inch suspension lift is minimal. You should be able to install the kit without changing and stock parts.
Depends on the profile of the tires going on it.
