Our CARLI SUSPENSION 3.25" BACKCOUNTRY SUSPENSION SYSTEM - DIESEL - 2013-2018 RAM 3500 includes top-of-the-line Carli SPEC 2.0″ Diameter, Remote Reservoir shocks, designed for ultimate all around comfort and ride quality. Whether you're driving on the road, in town, on the highway, towing, or off-roading at slower to mid speeds, these shocks are specifically tuned to deliver the best experience. The 6063 Aluminum construction and anodized body provide corrosion resistance, while the 5/8″ hardened steel chrome plated shaft adds durability. The shocks are also fully serviceable and rebuildable, and come with 1-piece bushings in the 6061 billet rod-ends. With a premium 5WT oil, these shocks offer consistent damping and a wide range of temperature variation. Plus, we stand behind them with a 1-year warranty.
The Details: Your truck will sit 3”-3.5” higher in the front (cab configuration dependent) with 50% more suspension travel than the factory platform thanks to the taller, lighter rate coil springs. The rear is lifted 2”-3” via the customer’s choice of a Progressive Add-A-Pack & Block combo or Full Progressive Leaf Pack. The Progressive Add-A-Pack/Block 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 at the cost of a 15% payload reduction from a standard 2500.
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; Billet Sway Bar Drop Brackets or the replacement Torsion Sway Bar. The Billet Drop Blocks shift the sway bar down and forward to ensure the factory end links cycle properly throughout the entire extended travel range. 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.
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, in the radius arm equipped Rams, lightened caster and slight rearward axle shift. 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 include Radius Arm Drop Brackets to recenter your caster adjustment and shift the axle forward to its new center of travel. Everything is included to support flawless operation of all components.
Wheel and Tire: This system will fit up to a 37” tire when utilizing wheels that are no more than 9” wide with 5.75-6” of backspacing. A 12.5” wide should fit with no rubbing on the factory radius arm and only minor trimming required, while a 13.5” will require more trimming and slightly more offset to fit properly. 35” tires will fit with VERY minimal, if any trimming. We Recommend running an 18” diameter wheel for optimal ride quality (more rubber = better small bump compliance) on a 35”-37” E-rated tire running 45psi front, 40psi rear when unloaded.
