For Ford F250, F350 Super Duty trucks with front leaf springs needing more front lift, the Zone 5-leaf mini pack is the answer. The lift is achieved from the thickness of the pack rather than re-arching the OE leaf pack. This will maintain ride quality while leveling your vehicle. The new mini pack will also help support front heavy loads such a snow plows, heavy bumpers, winches, etc. An adjustable front track bar is included. This allows you to perfectly center your front axle. Longer front shocks are optional.
