6 Inch Lift Kit | Rear Springs | Ford F-250/f-350 Super Duty 4wd (1999-2004)

Built for Ford Super Duty owners who want a level stance and 37-inch tire clearance, this 6-inch lift kit raises the front of your truck to match the rear for a balanced, aggressive look. Rough Country's design preserves factory ride geometry while unlocking serious ground clearance and the tire size you've been wanting.
