Carli Suspension 2017-2022 Ford Super Duty Pathfinder System 4.5"/5.5" Lift

The Pathfinder system strikes a balance between the Backcountry and Pintop, designed for Super Duty owners who want smooth on-road comfort with reliable off-road capability. It offers a controlled ride for light to moderate off-roading while excelling on pavement by absorbing bumps effortlessly for a comfortable daily drive. Featuring Carli-SPEC 2.5” aluminum shocks with a durable hard-anodized finish and high-performance red shock oil, it ensures lasting performance and heat resistance. With a 4.5" or 5.5” front lift depending on the year, progressive coil springs, and upgraded suspension components, the Pathfinder delivers a premium, dependable ride that enhances both comfort and capability.

The rear can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a “light” ¾-ton) or factory leaf-pack modifying Progressive Add-a-Pack (eliminates the factory block and maintains payload capacity; pairs with a rear bump stop drop). This is where the F250 and F350 are a bit different. Since 2008, the main spring packs on these two trucks is different; the F250 has a lighter rate spring pack (2 main leaf springs) than its 350 counterpart (3 main leaf springs). The F250 Add-a-Pack equipped systems are a nice improvement over stock; the F350 with the Add-a-Pack is still very stiff in the rear as the main pack doesn’t move much unless loaded. Carli recommends the Full Replacement Leaf Spring packs for both trucks but especially the F350 given the super-stiff factory springs. If you own an F250 built with the Tremor or high-capacity tow package, these are equipped with an F350 rear spring and should avoid the add-a-pack, as well. If capacity is a concern, an aftermarket airbag system should be installed to complement the Full Progressive Leaf Springs to restore the F350 capacity. It is best to use a system that will allow the airbags to disconnect from the lower mount during suspension cycling to ensure you’re able to take advantage of all your rear suspension travel. The Full Progressive Leaf Spring Pack will shift the axle slightly forward in the wheel well to ensure maximum tire clearance for a 37” M/T at full compression.

Lift Height Note: 2020 Super Duties were lowered 1” from the factory when comparing to the 2017-19. Further, the Tremor Package is a factory 2” lift on the 20-22 platform putting them 1” taller than the 17-19. As these all START at different heights yet utilize the same lifts, the stated lift height is different. They’ll all end up measuring the same with the lift installed!
