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 Starter Leveling Kit from Carli Suspension.

The Super Duty Starter system is designed for people who want a small suspension lift without the stereotypical ride-quality degradation associated with mass-produced "lift and leveling kits". The Carli Signature Seriesshocks build quality is unmatched for their price point and offer a nice boost in ride quality.

CARLI LEVELING START SUSPENSION SYSTEM COMPONENTS

The truck will sit 2.5" higher in the front and have more wheel travel thanks to the taller, lighter rate coil springs. Stainless Brake Lines and an Adjustable Track Bar round off the front end geometry correction while Caster Shims improve on the stock handling. The rear is outfitted with a Progressive Add-a-Pack lifting it 2" on F-250's and 1/2" on F-350's and matching rear shocks help keep the truck planted over rough terrain while maintaining factory towing and payload capacity. The 2.5" systems are designed to work with trucks equipped with the 2" rear block. Super Duties equipped with a 3-5/8" tall block from the factory will require the factory 2" tall Block to achieve a leveled stance with the Add-a-Pack. Part Number: 7C3Z-5598-L and 7C3Z-5598-K.

PROGRESSIVE ADD-A-PACK LEAF SPRINGS

This system is considered entry level; however, it's fully upgradeable and only requires an upgrade to one of Carli's many signature tuned shock packages to be converted to one of the higher-end systems. This system was designed with the Progressive Add-a-Pack and should not be run with the Full Progressive Leaf Springs.

ADD-A-PACK SPECIFICATIONS:
  • Built in the USA by Deaver Leaf Spring
  • Smooth progressive design
  • Supplied with U-bolts and hardware
  • Provides 2.0" of lift
  • OEM load capacity maintained, improved ride
  • 3.5" axle tube
  • SuperDuties equipped with a factory 3-5/8" Block will require the 2" Factory Block [7C3Z-5598-L, 7C3Z-5598-K] to achieve a level stance.

WHEEL AND TIRE FITMENT

On their 2.5" Ford Systems, Carli recommends 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, 37x12.5" 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.

IMPORTANT NOTES:
  • 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.

OPTIONAL COMPONENTS

LEAF SPRING SHACKLE SPECIFICATIONS:

Much of the jarring ride of the Super Duty rear can be attributed to the factory vulcanized bushings in the leaf spring pack and shackle. The factory shackle is very strong BUT the design is not conducive to a smooth ride. The Carli shackle is constructed of 1/4″ American cold-rolled steel. The mid-length gusset ensures no deflection while the serviceable bushings offer a far superior ride to the bind of the factory bushings.

  • Greasable and Rebuildable
  • Far better ride than factory shackle
  • 1/4" steel construction
  • Fits factory and Carli Springs
FABRICATED ADJUSTABLE RADIUS ARMS SPECIFICATIONS:

Icing on the cake, these arms add Additional Tire Clearance, Limit Strap Protection for your Front Shocks, 1/4" Boxed Steel Constructions, Serviceable 17-4 Stainless Spherical Bearings and Adjustable Caster Correction up to 3.5° over stock specs to leave Death-Wobble in the rear-view.

  • 0.5 - 2.5 degree of adjustable caster correction
  • 3/16 construction, fully internal gusseted with 1/2" additional tire clearance
  • 12" limit straps kit included
  • 17-4 stainless spherical joint for longevity and bind free cycling
HIGH MOUNT STEERING STABILIZER SPECIFICATIONS:

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.

  • Inside the Carli stainless stabilizer
  • Bolt in replacement for OEM stabilizer
  • Works on leveled and lifted trucks only
  • Will NOT work with dropped pitman arms
LOW MOUNT STEERING STABILIZER SPECIFICATIONS:

Bolt in steering stabilizer which compliments a Carli, or factory, high mount stabilizer. Adjustable from 70-200 psi to run neutral (no directional influence at 70psi) or at 200psi to counter the left-hand pull inherent to tires like Nitto Trail Grapplers. Run in conjunction with the Carli High Mount for the ultimate Dual, Opposing Steering Stabilizer combination that's infinitely adjustable.

  • Inside the Carli stainless stabilizer
  • Custom valved for larger tires, adjustable nitrogen pressure
  • Includes differential guard and clamp
  • Combines with high-mount stabilizer for opposing setup

Good stuff
Size: 50 sqft, Size: 50 sqft
Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.

Worked great at a budget price. I used it to damp a fiberglass loudspeaker horn. Easy to work with too.

Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.

Excellent product high quality.
Size: 36 sqft, Size: 36 sqft
This stuff definitely suprised how easy it was to work with. Not to mention it sticks very well. Don't put it on anything you may need to get back into. It will take the paint off of a service area. I have a 2018 dodge durango. I just had a aftermarket audio sytem installed. It was rattling so bad it was driving me crazy. I seen this stuff and decided to give it a try. Its a night and day difference no moore rattling. I box will be enough to do my back gate and all front and rear doors also. For the price you honestly can not beat it. If your on the fence about trying it don't be. You definitely won't regret getting it. Its worth every penny. You don't realize how much something rattling in your vehicle robs you of spund quality. Glad I made the decision. Now off to the other 4 doors. ,and then the roof. One of the things I really like was the fact it has multiple line to help you make even better cuts. Definitely will buy a gen.
