3" lift kit with 2" spring lifters would give 5". tho you'd probably have to have camber correction arms as well and check straps or dislocation cones. Bigger diameter tyres will lift the chassis up as well but then you will need to cut the arches back and fit plastic arches to cover the extra width.....but then with all that fitted you will attempt even rougher terrain and get stuck twice as often coz your running std diffs so you fit diff lockers and twin winches and then........ second thoughts just buy a tank, it will be cheaper
