CARLI SUSPENSION 23+ FORD F250/350 4X4 DIESEL 5.5" COMMUTER SYSTEM

*REQUIRED* - The Dominator System has been optimized for use with the Full Progressive Leaf Springs. This is the recommended option. Selecting anything other than this option will result in non-optimal operation of the system. Selecting "NO Rear Leaf Spring Selection" will result in an unknown ride quality and height result as all Carli Systems are optimized to either the Add-a-Pack or Progressive Leaf Springs.

*OPTIONAL* - 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.

*OPTIONAL* - Restores Factory capacity to reduced rate Carli Leaf Springs. Provides the best of both ends of the spectrum. Ride on Carli's soft-rate leaf springs when unloaded then air the bags up to level the chassis and support your load! Standard F250 will have 3.5" Axle Tube, High-Capacity Tow Package F250 will have 4". F350 will have 4" and DRW will be 4.5". We ALWAYS recommend measuring your axle before ordering as the above are guidelines and should be confirmed prior to ordering!

*OPTIONAL BUT RECOMMENDED* - When modifying the rear leaf springs (add-a-pack or Full Spring Pack) of the 2017+ Super Duty platform, there's a small chance you'll induce a driveline vibration around 70mph when under power from the rear driveline. These pinion shims will correct the angle to 4°-5°, ideal for our lifted applications. Although these will not be "required" on every truck, we've found the 4°-5° spec to be superior in our applications and these are FAR easier to install initially than correctively.

*OPTIONAL* - 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.

*OPTIONAL* - 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.

*OPTIONAL* - 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.

*OPTIONAL* - For trucks with 2-piece driveshafts; lowers the carrier bearing to eliminate take-off shudder resulting from additional driveshaft angle from the lifted suspension.
