The Carli Backcountry system can best be described as being built for truck owners that "use their truck as a truck." So, what does this mean? Basically, the Backcountry is ideal for those that daily drive, tow, plus like to hit some trails on the weekends, but aren't looking to see daylight under the tires out in the dunes. The benefit of the Backcountry over the Commuter series is the remote reservoir that not only LOOKS cool, but also allows the shock to maintain its temperature, meaning you won't experience shock fade when on rough surfaces for any extended period of time, as a traditional IFP shock will tend to do.

The Backcountry 2.0 system is designed for people seeking the best ride on and off-road on a budget; perfect 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 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.

The Details: Your truck will sit 3"-3.5" higher in the front (cab configuration dependent) with 50% more suspension travel than the factory platform thanks to the taller, lighter rate coil springs. The rear is lifted 2-3" via either Carli's Progressive Rate Add-A-Pack & Billet Block or Carli's Full Replacement Progressive Leaf Springs.

When pairing added down-travel with the taller ride height, the position of the factory, front sway bar will need to be altered as well. For this, you have two options; Billet Sway Bar Drop Brackets or the replacement Torsion Sway Bar. The Billet Drop Blocks shift the sway bar down and forward to ensure the factory end links cycle properly throughout the entire extended travel range. Carli's optional Torsion Sway Bar removes the entire factory sway bar assembly replacing it with a torsion bar supported by fabricated drop brackets and delrin bushings. Fabricated sway bar arms and dual 5/8" FK heim end links round off the package. This is the single best bang for the buck, ride-quality upgrade offered by Carli Suspension.

When lifting the front end of a straight axle truck, the front axle is pulled off-center unless the proper linkages are addressed. Three inches of front lift equates to an axle shifted toward the driver's side 3/4" and, in the radius arm equipped Rams, lightened caster and slight rearward axle shift. This system includes an Adjustable Track Bar to push the axle back toward the passenger side and provide a stronger link with less deflection for the lifted application. Also included are Radius Arm Drop Brackets to recenter your caster adjustment and shift the axle forward to its new center of travel.

Everything is included to support flawless operation of all components. You will receive bump stop drops to ensure the shocks are cycling in their designed travel range as well as a rear track bar drop bracket minimizing the rear end "wag" associated with opposing track bar suspension designs.

Wheel and Tire: This system will fit up to a 37" tire when utilizing wheels that are no more than 9" wide with 5.75-6" of backspacing. A 12.5" wide should fit with no rubbing on the factory radius arm and only minor trimming required, while a 13.5" will require more trimming and slightly more offset to fit properly. 35" tires will fit with VERY minimal, if any trimming. Carli recommends running an 18" diameter wheel for optimal ride quality (more rubber = better small bump compliance) on a 35"-37" E-rated tire running 45psi front, 40psi rear when unloaded.

Payload: After a great deal of test runs with various weights loaded in the bed of Carli test truck, it was quickly determined that the factory payload was nearly untouched, given all of the updates Carli had made to the rear of the truck.

Testing: What would a Carli kit be if it weren't getting absolutely filthy out in the dirt or getting the shocks up to temperature? In true form, Carli made absolutely sure the truck could also perform offroad by making numerous trips to the deserts of Barstow, El Cajon and Phoenix to really confirm how the new packages worked. The conclusion? These trucks can boogie just like the previous years!
