2003-2009 Ram HD 4x4 Diesel 3.0" Lift Commuter System (CS-D3-COM-CS-03-D)

Needed to complete this build — skip only if your truck already has one installed. 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, we offer 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. This System has been optimized for use with the Torsion Sway Bar; this sway bar upgrade is a HUGE ride quality upgrade. 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 - i.e.: those with snow-plows, in-bed campers or who are constantly hauling to the capacity of the truck.

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. Selecting "NO Rear Leaf Spring Selection" will result in an unknown ride quality and height result as all Carli Systems are optimized to either the Add-a-Pack or Progressive Leaf Springs. *The HD Options is ONLY for those running a CONSTANT 1,000lbs in the bed at all times.*

Much of the jarring ride of the leaf-spring rear can be attributed to the factory vulcanized bushings in the leaf spring pack and shackle. The factory shackle is very strong BUT the design is not conducive to a smooth ride. The Carli shackle is constructed of 1/4″ American cold-rolled steel. The mid-length gusset ensures no deflection while the serviceable bushings offer a far superior ride to the bind of the factory bushings.

when adding oversized tires, it's always recommended to upgrade one's stabilizers. We recommend the low-mount for those running 35s and an opposing setup for those with 37s.
