Description:

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. Utilizing Fox 2.0” 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 Fox 2.0s boast extruded aluminum construction with a clear anodizing for corrosion resistance, are fully rebuildable and are built with hour-glass bushings in the rod-ends. Fox builds these shocks with their legendary red shock oil that flows well down to -55° F.

The truck will sit 4.5” 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 while Sway Bar Links or Drop Brackets reset the sway bar engagement point. 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 (maintains factory payload capacity and pairs with the factory 3-5/8” block). 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 than its 350 counterpart. 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 capacity is a concern, the Full Progressive Leaf Springs can be supplemented back to the factory capacity of a SRW F350 with the addition of our Long-Travel Airbags. 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.

If ordering this kit with an Add-a-Pack, Super Duties equipped with a 2" tall block from the factory will require the factory 3-5/8" tall Block to achieve a leveled stance with the Add-a-Pack. Part Number: 7C3Z-5598-HB, 7C3Z-5598-JB

Wheel and Tire:

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. For more details, see our article on wheel and tire selection and tire pressures

System Notes:

Wheels - Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5" of Backspacing on 4.5" Lift Systems.

Recommended Configuration - Carli 4.5" Systems are Designed and Tested on Vehicles with 17"-18" Wheels with 37", E-Rated Tires. Stock wheels and tires or running a larger wheel diameter will result in a stiffer ride

Add-A-Packs - Super-Duties equipped with a factory 2" Block will require the 3-5/8" Factory F350 Block [7C3Z-5598-HB, 7C3Z-5598-JB] to achieve a level stance

Leaf Springs - Full Replacement Leaf Spring Option Requires NO BLOCKS to achieve level Stance

Rear Driveshaft - Trucks equipped with a 2 piece driveshaft will require CS-CARRIERDROP-F to ensure proper driveline angles
