2023-2026 Superduty 4x4 Diesel 5.5" Backcountry System (CS-F55-BC-CS-23)

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 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

Bolt-in replacement for the factory stabilizer. Adjustable 70-200 psi — run neutral or counter the right-hand pull of aggressive M/T tires like Toyo Mud Terrains. Stainless, leveled-and-lifted trucks only, not compatible with drop pitman arms.

Direct bolt-in 3″ receiver rated to 16,000 lbs. Cranks your oversized spare out of the bed and into the factory location with a 3-way tie-down — up to 38″ tire. May require exhaust modification; uses ⅝″ × 4″ hitch pin.
