The Super Duty Backcountry 2.0 System is perfect for those who want the best of both worlds—top-notch on-road comfort and the ability to tackle off-road adventures without breaking the bank. Designed for the 8,500lb Super Duty, this system allows you to enjoy dirt-road fun while maintaining the ride quality and usability that your truck was built for.

Key Features:

  • Advanced Shock Technology:
    • Carli SPEC 2.0″ Diameter Remote Reservoir shocks are built from 6063 aluminum with an anodized body for superior corrosion resistance.
    • Features a 5/8″ hardened steel chrome-plated shaft, ensuring durability and longevity.
    • Fully serviceable and rebuildable, these shocks come with 1-piece bushings in 6061 billet rod ends for optimal performance.
    • Filled with premium 5WT oil for consistent damping and excellent lubricity across a wide temperature range.
    • Backed by a 1-year warranty, serviced by Carli for your peace of mind.

Ride Height and Travel Enhancements:

  • Increased Front Height:
    • Your truck will sit 3.5” higher in the front, thanks to lighter rate Carli Coil Springs that provide more wheel travel.

  • Optimized Front Geometry:
    • Adjustable Track Bar: Centers the front axle for enhanced stability.
    • Stainless Brake Lines: Ensure firm braking performance with adequate line for increased travel.
    • Radius Arm Drop Brackets & 1° Caster Shims: Correct caster angles for proper tracking.
    • High-Clearance Bump Stop Drop: Protects the springs from contacting the factory bump stop.

Sway Bar Options:

  • Enhanced Sway Bar Geometry:
    • Choose between:
      • Sway Bar Drop Bracket: More economical, maintains factory sway bar end links.
      • Extended Sway Bar Links with Relocation Brackets: A robust option for improved ride quality.
    • Upgrade to our full replacement Torsion Sway Bar for enhanced compliance and articulation, resulting in only slightly more body roll.

Rear Suspension Customization:

  • Leaf Spring Options:
    • Opt for a Full Progressive Spring Pack (reducing capacity to a "light" ¾-ton) or a Progressive Add-A-Pack that maintains payload capacity while eliminating the factory block.

  • F250 vs. F350 Considerations:
    • The F250 has a lighter rate spring pack (2 main leaves), while the F350 features a stiffer setup (3 main leaves).
    • The F250 Add-A-Pack provides a noticeable improvement over stock, while the F350 Add-A-Pack may remain stiff unless loaded.

  • Capacity Solutions:
    • For optimal performance, we recommend the Full Replacement Leaf Spring Packs, especially for F350 models with stiff factory springs.
    • If capacity is a concern, consider an aftermarket airbag system to restore F350 capacity. Ensure the system allows for disconnection during suspension cycling to maximize rear travel.
    • The Full Progressive Leaf Spring Pack shifts the axle slightly forward for maximum tire clearance with 37” M/T tires at full compression.

Installation Notes:

  • A proper rear-high stance requires installation of the Add-A-Pack or Full Progressive Leaf Spring Pack. Without these, an F250 may sit rear-low.
  • If a Carli rear spring option is not purchased, a taller 2017-19 Ford 3″ rear block can be installed for a leveled stance, though rear ride quality may not be optimized (Factory Block PN: HC3Z-5598-A and HC3Z-5598-B). Which can be found HERE

Wheel and Tire: Factory Wheels SHOULD NOT be run with oversized tires. They’re known to rub the radius arm, sway bar and most concerning – Brake Lines. Factory tires and factory wheels will work without issue but we DO NOT recommend running oversized tires on factory wheels. On our 2.5” Ford Systems, we recommend 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, 37×12.5” 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. For more details, see our article on wheel and tire selection and tire pressures.
