you can use rear lift block if you plan on flipping your rear leafs to on top of the axle. also.. for the price he is asking u could add like 100-150 more and just get a brand new kit... old kits can have fracture stress etc that he wont wont tell you about.
Rough Country 680.00
Tuff Country 500.00
Plus other brands..
YOU NEED TO BE AWARE OF WHAT COMES WITH LIFTING OUR Ex....
Not just a lift kit, itll stress your brake lines, which means extended brake lines, new alignment.. most shops will not align older rides that have been lifted..
Proper Pitman Arm Length.. blablabla
If your looking for height and tire clearance you should just do a 3" Body lift.. which is a complete lift for 200 or less!
