2017-2022 Powerstroke Backcountry 4.5-5.5" Lift Kit (CS-F45-BC-CS-17)

Needed to complete this build. Skip only if your truck already has one installed.

The Backcountry System has been optimized for use with the Full Progressive Leaf Springs. This system is also compatible with the Progressive Add-a-Packs but there will be a notable ride quality difference on and off-road. Add-a-Packs are NOT recommended for the F350 (or any F250 equipped with the High Capacity Tow or Tremor Package).

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.

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 Dualies will be 4.5". We ALWAYS recommend measuring your axle before ordering as the above are guidelines and should be confirmed prior to ordering!

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.

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.

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.

Get your over-sized spare out of your bed - crank it into the factory location and secure it with our 3-way tie-down with the Carli Trophy hitch. Boasting 16,000lbs. of capacity via the 3" hitch receiver, direct bolt in installation, and up to a 38" spare tire in the factory location!
