Carli 3.5" Leveling Suspension System 23-26 Ford F-250/350 6.7L Powerstroke
Looking for an economical upgrade to your SuperDuty to increase ride quality and level out your stance? Maybe you're confused about what you need or don't need. Carli Suspension is one of the best in the business in putting together exactly what you need with quality and price that will have you coming back. Introducing the Carli Suspension 3.5" Leveling Kit for Ford Powerstroke. High-quality coils, shocks, brake lines, and bump stops turn your Ford into something more than just a work truck.
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.
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 with the factory main pack; it’s for this reason Carli advises against upgrading to the Full Progressive Spring Pack (too much rebound valving for a lighter rate spring).
Front Sway Bar Option
- No Sway Bar: The Communter System is optimized to be used with a torsion sway bar giving a huge ride quality upgrade. Staying with the factory sway bar is not recommended unless you have a truck with a snow plow, or in-bed camper, or constantly hauling to capacity.
-
Sway Bar Drop Bracket: The economical solution as it keeps the Factory Sway Bar End Links but corrects the factory sway bar geometry.
- End Link and Drop Bracket Kit: This kit combines End Links and Drop Brackets for perfect sway bar position and excellent articulation.
-
Sway Bar Kit and End Links: This kit replaces your immoveable factory sway bar with a custom torsion bar and has brackets and links to make sure it fits as it should. There will be a huge ride quality improvement when you install this kit.
Rear Leaf Spring Option
- No Rear Leaf Spring: Unless you are driving a F-350 or a F-250 Tremor, you 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!
- Carli Add-A-Pack: A nice improvement over stock, there will be a noticeable ride quality upgrade on and off-road. The Add-A-Pack is not recommended for F-350, F-250 with High Capacity Tow, or Tremor Package as their factory springs are best left unmodified with this package.
Leaf Spring Shackle Option
The SuperDuty can have a rather jarring ride quality in its rear due to factory vulcanized bushings in the leaf spring pack and shackle. While the shackle is tough, its design didn't take into account ride quality. Replace it with the Carli shackle to get both strength and smoothness.
Pinion Shim Kit Option
Recommended for when you are modifying rear leaf springs, these shims correct an angle issue for your driveline that can cause vibrations once you get 70mph. It's better to take care of the issue now when you install your suspension kit and then realize it later.
Adjustable Radius Arms Option
Put the nail in "Death Wobble"'s coffin with these radius arms from Carli. A full .5° to 2.5° of adjustable Caster correction comes with these full-length internal structure arms.
Steering Stabilizer Option
A lift kit brings many benefits but it does come with some added snags to your drive comfort. Smooth them out with steering stabilizers. Choose high, low, or both for the ultimate dual opposing combination you can adjust more times than you can count.
