CS-D3-COM-CS-03-D | Carli Suspension Commuter System 3.0 Inch Lift Kit With Carli Spec 2.0" IFP Shocks For Ram 2500/3500 4WD | 2003-2009 | Diesel

The Commuter 2.0 system is designed for people seeking the best on-road ride quality on a budget. 

A “Base Kit” SKU must be accompanied by the SKU of a Sway Bar and Leaf Spring option to form a complete system.

Front Lift: 3.00" /  Rear Lift: 1"-2" / Front Travel: 10" /  RearTravel: 11.3" / Shock Type: 2.0" / Tire Fitment: 37" x 12.5"

The mono-tube, internal reservoir, Carli SPEC 2.0 boasts 6063 Aluminum construction, anodized body for corrosion resistance, 5/8″ hardened steel chrome plated shaft, full serviceability & re-buildability 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 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 maintains load capacity and 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 (when compared to when compared to the factory springs or add-a-pack) throughout the entire usable travel stroke reducing payload to a “light” 3/4-ton spec. This can be brought back to factory capacity with the use of Carli Long Travel Airbags to achieve the best ride and adjustable rear load capacity!

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 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 (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. We also recommend the purchase of a set of extended control arms to shift the axle forward to its new center of travel.

Wheel and Tire: This system will fit up to a 35” tire with stock control arms (we recommend purchasing our extended, Mild Steel Control Arms) on wheels with 5.75-6” of backspacing. If running factory wheels, we recommend an All Terrain 35” tire to avoid rubbing. For 37” tire fitment, our High-Clearance Control Arms and Adjustable Track Bar can be paired to a wheel with 5.75” 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:

Customization Information

Sway Bar

*REQUIRED* - With the lift provided by the coils and the extended travel of the shocks, the front sway bar must 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.

 Rear Leaf Options

*REQUIRED* - The Commuter System has been optimized for use with the Full Progressive Leaf Springs.
