2003-2009 Ram 2500/3500 Diesel Backcountry Suspension Lift Kit - Off-Road Performance Upgrade for Heavy Duty Trucks (Ideal for Overlanding, Towing & Off-Road Adventures)

THE BACKCOUNTRY SYSTEM:

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 is built with 1-piece 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. 

SWAY BAR OPTIONS

With the lift provided by the coils and the extended travel of the shocks, it's imperative the front sway bar be addressed. For this, you have two options. The Carli Sway Bar End links provide a longer link (utilizing the factory upper pillow bushing) allowing for reuse of the factory sway bar. Maintaining the factory sway bar through use of the Sway Bar Links is only recommended for customers requiring the stiff rate of the factory sway bar 

This System has been optimized for use with the Torsion Sway Bar; this sway bar upgrade is a HUGE ride quality upgrade. 

• Easily the best "bang for the buck" upgrade for ride quality
• Allows front suspension to move freely without giving up control
• For trucks with 0-3" of front lift
• Requires removal of electronic sway bar on Power Wagons
• Torsion Bar may be Black or Silver Zinc; depends on supply-chain availability. NOT requestable.

REAR LEAF SPRING OPTIONS

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. The HD Options is ONLY for those running a CONSTANT 1,500lbs in the bed at all times.

Progressive Add-A-Pack:

• Replaces lower overload spring
• More predictability and Spring Progression Keeps Tires Planted
• 1" lift matches to our 3" front systems
• Includes U-Bolts and Center Pins
• Fitment: 2003-13 Ram 2500 4x4, Diesel
• Fitment: 2003-18 3500 4x4, Diesel
• Will NOT fit 2013+ 3500 with Factory Air-Assist

Full Progressive Leaf Spring Kit:

• 2" rear lift maintains slight rear-high stance with Carli 3" Systems
• Softens initial spring rate at ride height
  
• Minimizes axle wrap/wheel hop
• Reduces payload to "light" 3/4-ton capacity
• Capable of 15" of suspension travel with factory shackle
• Fits 4" Axle Tube

Full Progressive HD Leaf Spring Kit

• 2" rear lift maintains slight rear-hight stance with Carli 3" Systems
• Softens initial spring rate at ride height
• Minimizes axle wrap/wheel hop
• Designed for those with 1,500lbs. in bed at all times
• Capable of 15" of suspension travel with factory shackle
• Fits 4.0" Axle Tube

The Details:

Your truck will sit 2.5”-3” higher in the front (year/cab configuration dependent) with 50% more suspension travel than the factory platform thanks to the taller, lighter rate coil springs. The rear is lifted 1”-2” via the customer’s choice of a Progressive Add-A-Pack or Full Progressive Leaf Pack.

The Progressive Add-A-Pack replaces the factory overload with a 5-Leaf, progressive pack that changes the final rate of the spring pack keeping the rear planted while increasing traction and predictability.

The optional Full Progressive Leaf Pack replaces the entire factory leaf spring assembly increasing travel and drastically increasing comfort throughout the entire usable travel stroke at the cost of a 15% payload reduction from a standard 2500. This payload reduction can be supplemented back to factory 3500 SRW capacity with the addition of the Long Travel Airbags for the best of both worlds; ride quality and payload capacity/load control.

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, we offer two options (unless 1994-2002, then there’s only one); extended, Sway Bar End Links or the replacement Torsion Sway Bar. The End links are equipped with ½” FK Rod-Ends and in-house machined 17-4 stainless bodies that are extended over stock to reset the sway bar engagement points. Factory pillow-bushings are re-used to assemble the sway bar to the lengthened link.

Carli’s 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 (in close competition with the full progressive leaf spring upgrade).

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 ¾” and back toward the cab ½”. 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.
