Base Kit Includ
Please note: A “Base Kit” SKU must be accompanied by the SKU of a Sway Bar and Leaf Spring option to form a complete system. 2003-07 Rams MUST convert to factory “T-Style” steering.
Description:
Where the Dominator 3.0” is more balanced, the tuning in the UnChained System is enough to put the build quality of the rest of the truck to the test. At this level of suspension, customers should install a cage as the off-road capability far exceeds the capability of the truck itself.
The front boasts massive, long-travel 3.5” King Shocks with an off-road oriented tune; the rear, 3.0” 4-Tube King Bypass Shocks. The 4-tube bypass will have far more bottom-out resistance than their smooth-body counterparts and their capability is user tunable to achieve exactly the rear ride desired by the purchaser (More on this in “The Details”).
What does all this mean? Uncompromised off-road ability with an amazing on-road ride resulting in a truck that’s a blast to drive in all environments.
Wheel and Tire:
This system will fit up to a 37” tire on wheels no more than 9” wide with 4.5” of backspacing. 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 4.5" of Backspacing on 6" Systems
- Tires - 37", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 45F/40R
- Recommended Configuration - Carli 6" Suspension 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.
- Endlinks - 2010-2013 vehicles have 2 possible sizes of Sway Bar End Links. Place a socket on the nut that compresses the rubber End Link bushings; fitment of an 18mm socket will indicate the need for the 12mm Extended End Link.
- Torsion Sway Bar - Selection of the Torsion Sway Bar Replacement will not Require size selection as the entire sway bar assembly is replaced.
- Front Drive Shaft - The front drive shaft MUST be lengthened 2"
- Rear Drive Shaft - Rear Driveshaft must be checked for 1-piece or 2-piece units. It is recommended that 2 piece Driveshafts order a carrier bearing drop, PN# CS-CARRIERDROP-D
- Pitman Arm - A drop pitman arm is REQUIRED for 6" suspension kits. Pitman Arm Selection: [2003-2008: CS-PITMAN6-03]; [2009-2013: CS-PITMAN6-09]
- Steering Linkage - Carli 6" suspension kits MUST run T-style steering linkage. Y-style linkage does not have enough angle of articulation to support the additional lift height and travel.
