Manufacturer description: 12-13 RAM 2500/2012 3500 4X4 DIESEL SRW 6.0" UNCHAINED SYSTEM
From Carli Suspension
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.
The Details: The Carli 6” Systems are an entirely different animal than the 3” offerings. There is no entry level; every system is equipped with a custom tuned shock package and Radius Arm Conversion. Further, the drop brackets that affix the radius arms to the frame bolt on with no modification to the existing, factory control arm brackets (ensuring the truck can be returned to stock). The arms themselves boast “X” bracing internal to their gusseted, clam-shell structure and are constructed with 3” Currie Johnny Joints and an internally gusseted, 1-piece Crossmember (Dominator and UnChained only) making them both serviceable and nearly indestructible.
