so im trying to make my truck taller and get some bigger tires, i currently have a 2" spacer and 275 60 20s. my parents wont let me buy a lift kit idk why? so im looking at a 3 inch body lift and keep my 2 inch spacers on and either get some 35s or 34.5 inch tires. i was wondering the pros and cons of a body lift and what tools would be need to install it? thanks.
