depends on what your looking for. if your looking to build the 4runner into a rock crawler/trail vehicle then i'd hold off on a lift kit for IFS besides cranking the torsion bars and putting in an add-a-leaf in the rear suspension. you will be amazed at where you can get it with just that without breaking stuff. just expect alot of body roll and having 1 front tire off the ground. more aggressive tires, add a locker or weld the spider gears, and get rock sliders/bumpers.
