Our Carli SPEC 2.0" Diameter, Remote Reservoir shocks have been specifically developed to provide all-around comfort and ride quality for various purposes including on-road, in town, highway, towing/hauling, and slow to mid speed off road use. Constructed with 6063 Aluminum and anodized for corrosion resistance, these shocks feature a 5/8" hardened steel chrome plated shaft, full serviceability, and rebuildability. Additionally, they come equipped with 1-piece bushings in the 6061 billet rod-ends. These high-quality shocks use premium 5WT oil to ensure lubricity, consistent damping, and a wide temperature range. You can rely on their durability as we back them with a 1-year warranty and offer servicing through 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 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 the Sway Bar Link & Drop Brackets Kit resets the sway bar engagement point. The End Link Kit is listed as an “option”, but it’s necessary to run. We plan to release a Torsion Sway Bar in the near future so the end-link options were pulled from the base kit and made selectable in anticipation of the second option. 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 included Carli Fabricated 2” 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.
