The Backcountry System is made for those seeking the best ride on and ofFroad without breaking the bank; You’re no longer limited to the highway while gravel roads become dull as you can drive them at speed with one hand on the wheel.
Carli’s Backcountry 2.0 System delivers a keen balance of on-road stability and mild ofFroad ability for a reasonable price. The base system touches all critical components, addressing wheel travel, proper geometry, smoothness, and durability while delivering an aggressive level stance. The kit is based on Carli-Spec 2.0-inch diameter remote reservoir shocks. Carli engineers developed a valving tune that addresses on-road, in-town, highway driving, towing and/or hauling, as well as slow- to medium-speed ofFroad use. The shocks boast 6063 aluminum construction, fully anodized body for corrosion resistance, 5/8″ hardened steel chrome plated shock shaft, a fully serviceable/rebuildable design, and 6061-billet rod-ends with one-piece bushings. This suspension transforms your truck into a rig that is smoother than stock on the highway but has the moxie to tackle mild trail running and ofFroading with ease.

Lift Height Note: 2020 Super Duties were lowered 1” from the factory when comparing to the 2017-2019. Further, the Tremor Package is a factory 2” lift on the 20-22 platform putting them 1” taller than the 17-19. As these all START at different heights yet utilize the same lifts, the stated lift height is different. They’ll all end up measuring the same with the lift installed!

*ONE REQUIRED* - The Backcountry System has been optimized for use with the Torsion Sway Bar; this sway bar upgrade is a HUGE ride quality upgrade. Maintaining the factory sway bar through use of the Sway Bar Drops & Extended Link Kit is only recommended for customers with snow-plows, in-bed campers or who are constantly hauling to the capacity of the truck.
*REQUIRED* - 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). More information can be found in the description at the bottom of this page.More information is available in the long description at the bottom of this product page. 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 BUT RECOMMENDED* - 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.
SKU: CS-FSHACKLE-11
- Greasable and Rebuildable
- Far Better Ride than Factory Shackle
- 1/4" Steel Construction
- Fits Factory and Carli Springs
*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.

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* - 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.

BACKCOUNTRY 2.0 SYSTEM - IN DEPTH
Utilizing Carli SPEC 2.0″ Diameter, Remote Reservoir shocks, we've developed a tune that delivers all around comfort and ride quality designed for on-road, in town, highway, towing/hauling as well as slow to mid speed off road use. The remote reservoir Carli SPEC 2.0 boasts 6063 Aluminum construction, anodized body for corrosion resistance, 5/8″ hardened steel chrome plated shaft, full serviceability & rebuildability and are built with 1-peice bushings in the 6061 billet rod-ends. These shocks are spec'd with a premium 5WT oil to balance lubricity, consistent damping and the widest available range in temperature variation. We back these with a 1-year warranty, serviced by Carli.
The Super Duty Backcountry 2.0 system is designed for people seeking the best ride on and off-road quality on a budget; basically, the Commuter for those that want to have a little dirt-road fun in their 8,500lb truck without losing the on-road ride quality or usability for which the truck was designed. You're no longer limited to the highway while gravel roads become uninteresting as you can drive them at speed with one hand on the wheel.
The truck will sit 5.5" higher in the front and have more wheel travel thanks to the taller, Progressive Rate Coil Springs. Radius Arm Drop Brackets reset the pivot point and keep the travel linear for the best ride. The front Sway Bar Geometry will need to be addressed with your choice of a Sway Bar Drop Bracket & Carli Extended Sway bar End Link combination or, for those seeking the most possible ride quality, we offer our full replacement Torsion Sway Bar that lightens the most commonly neglected spring rate - the factory sway bar. From the Torsion Sway bar upgrade, one can expect a far more compliant feel and increased articulation with only slightly more body roll. Bump Stop Drops protect the shocks from over-compressing, the Adjustable Track Bar centers the front axle and Stainless Brake Lines firm up braking and ensure there is enough line for the newfound travel. To round off the front end, we include Caster Shims to tighten the steering.
The rear can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a "light" ¾-ton) or factory leaf-pack modifying Progressive Add-a-Pack (eliminates the factory block and maintains payload capacity; pairs with a rear bump stop drop). This is where the F250 and F350 are a bit different. Since 2008, the main spring packs on these two trucks is different; the F250 has a lighter rate spring pack (2 main leaf springs) than its 350 counterpart (3 main leaf springs). The F250 Add-a-Pack equipped systems are a nice improvement over stock; the F350 with the Add-a-Pack is still very stiff in the rear as the main pack doesn't move much unless loaded. We recommend the Full Replacement Leaf Spring packs for both trucks but especially the F350 given the super-stiff factory springs. If you own an F250 built with the Tremor or high-capacity tow package, these are equipped with an F350 rear spring and should avoid the add-a-pack, as well. If capacity is a concern, an aftermarket airbag system should be installed to complement the Full Progressive Leaf Springs to restore the F350 capacity. We recommend a system that will allow the airbags to disconnect from the lower mount during suspension cycling to ensure you're able to take advantage of all your rear suspension travel. The Full Progressive Leaf Spring Pack will shift the axle slightly forward in the wheel well to ensure maximum tire clearance for a 37" M/T at full compression.
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 4.5" Ford Systems, we recommend 17"-18" wheels, no more than 9" wide with 5" of backspacing with a 37", E-Rated Tire. 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.
