Quick Ship SKU #: CS-FLVL-SIG-17 Carli 3.5" Leveling Suspension System 20-23 Ford F-250/350 6.7L Powerstroke

Sure, you could add a simple spacer on top of your coils to level our your SuperDuty, but wouldn't you rather actually improve the ride quality while also getting that level stance you're after? If so, check out this Leveling Kit from Carli Suspension.

The Super Duty Leveling System is designed for people seeking the best on-road ride quality on a budget. Utilizing the Signature Series shocks, Carli developed a tune that delivers all around comfort and ride quality designed for on-road, in town, highway, and towing/hauling. Unlike most of Carli's suspension systems, the Leveling System was tuned with 20", factory wheels on factory Michelin tires given many in the entry level, 3.5" lift market want the most bang for their buck and will continue to run the factory wheels and tires.

This system will not achieve a proper rear high stance without the installation of the add-a-pack; it will sit slightly rear low with no rear option added!  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. For this reason, we do not recommend the Add-a-pack on an F350 or Tremor (as they all have F350 springs); you’re best to leave the factory springs unmodified. One can install the 3″ factory rear block for a leveled stance but rear ride quality will not be optimized (Factory Block PN: HC3Z-5598-A and HC3Z-5598-B). The Add-a-Pack installs in place of the lower, factory overload spring effectively making the factory leaf spring pack progressive in nature. In the 2020 platform, the factory 2″ block is eliminated with the installation of the Add-a-Pack; thus, axle wrap and wheel hop are non-existent. A rear bump stop drop is included to bridge the distance lost by removing the factory block.

Payload capacity is maintained and the rear end becomes a touch softer while being far more planted and predictable. The custom tuning in the rear Signature Series Shocks is optimized to control the combination of our Progressive Add-a-Pack combined with the factory main pack; it’s for this reason we advise against upgrading to the Full Progressive Spring Pack (too much rebound valving for a lighter rate spring).

OPTIONAL COMPONENTS:

Carli Adjustable Track Bar: Centers the axle at the new ride height utilizing a stronger suspension/steering link to prevent death-wobble and improve overall tracking and steering feel.

Sway Bar Options: The Leveling System will ride best with the Torsion Sway Bar. Maintaining the factory sway bar through use of the Sway Bar Drops or Extended Link Kit is only recommended for customers with snow-plows, in-bed campers or who are constantly hauling to the capacity of the truck.

Rear Shocks: Tuned to the factory leaf springs, these rear shocks balance the rear-feel to match the custom tune in your newly leveled Super Duty.

High Mount Steering Stabilizer: This is a Bolt in replacement for the factory stabilizer. Adjustable from 70-200 psi to run neutral (no directional influence at 70psi) or at 200psi to counter the right-hand pull inherent to tires like Toyo Mud Terrains.

Wheel and Tire: Factory Wheels SHOULD NOT be run with oversized tires. They’re known to rub the radius arm, sway bar and most concerning – Brake Lines. Factory tires and factory wheels will work without issue but we DO NOT recommend running oversized tires on factory wheels. On the 3.5” Ford Systems, Carli  recommend 17”-18” wheels, no more than 9” wide with 5.5” of backspacing with Carli Fabricated Radius Arms or 5” Backspace with factory arms; 5” will require a bit more trimming. Tires, 37×12.5” will fit with some trimming; 35” will likely fit without trimming. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter.

• WHEELS: Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5"-5.5" of Backspacing on Leveling Systems
• TIRES: 35", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 45F/40R.
• RECOMMENDED CONFIGURATION: Carli Leveling Systems are Designed and Tested on Vehicles with 17"-18" Wheels with 35", E-Rated Tires. Stock wheels and tires or running a larger wheel diameter will result in a stiffer ride.
