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

Built for Ford Super Duty owners who want a level stance and room for bigger rubber — this 6-inch lift kit raises the front of your truck to match the rear, giving you that factory-engineered look with improved ground clearance and tire capacity up to 37 inches with proper wheel backspacing.
