THE MOST PERFORMANCE OUT OF ANY BOLT-ON RAM SUSPENSION SYSTEM YOU CAN GET, PERIOD!

The UNCHAINED 3.5 is Carli's most advanced off-road performer capable of more bottom-out resistance and definitive offroad control than any other system ever released by Carli Suspension. Starting with the biggest shock that can safely fit without extensive modifications, they integrated all major suspension components into one monolithic offroad machine that delivers the absolute best in dirt, highway, and all-terrain performance.

Please see notes below regarding available options and requirements.

Every part of this system was selected and enhanced to extract every last bit of control, dampening, and articulation; the High Clearance Control Arms matched with the Torsion Sway Bar utilize every last millimeter of wheel travel from the gratuitous speed-sensitive 3.5" King Race Shocks up front, where as the weld-on Rear Shock Mounts maximize travel and strength from the position-sensitive 4-Tube 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 you. Extensive shock tuning sessions has lead Carli to bring you the most aggressive, finest performing system ever engineered.

What does all this mean? Uncompromised off-road ability with a civil on-road ride resulting in a truck that's a blast to drive in all environments.

The Details: This system requires is modeled around Carli's exclusive fabricated long arm system, designed to get you the most wheel travel with the least amount of lift possible. In order to install these, you will be required to cut off the factory control arm mounts in favor of the Carli Drop Brackets to house the internally gusseted, fully fabricated Long Arm System. These arms are over 50% longer than the factory arms boasting 3/16" cold-rolled steel construction, internal gusseting, extended travel capability, more linear travel stroke and a better ride quality given their length and position parallel to the ground.

To take advantage of the Long Arm's capability, included are 6.25" tall, slide over-design shock towers to ease installation and accommodate the longer (11.25" Travel) shocks, included 1" front bump stop drops and limit straps to ensure you can dish repetitive beatings to the King 3.5" shocks with confidence of full and safe utilization of the shock's travel. In a short arm truck, it's not uncommon to see 7" of up-travel (metal to metal) and 3" of down-travel. The combination of the long arm system's 6.25" tall tower and 1" bump drop allows for the 11.25" travel shock and shifts the front axle's operating range down 1"; the result, 2.25" more down-travel when compared to a short-arm system only sacrificing 1" of up-travel. This is a far more balanced setup spec'd with 6" of up travel and 5.25" of down-travel ensuring the front end maintains contact over rough terrain. If you're looking for a great daily driver to beat up on the weekends, grab a Performance 2.5"; if you're looking for a no-compromise off-road system to push the envelope of which the Ram platform is considered capable, this is it.

The UnChained system features front Carli Signature tuned, King 3.5" remote reservoir shocks so large, you will need to bore the factory spring buckets for them to cycle properly. As the old adage goes, there's no replacement for displacement. In an effort to provide you with the best product, Carli does not utilize standard off-the-shelf King shocks. They spent countless hours dialing in an off-road oriented, Long-Arm tune to ensure they maximized the performance of these monster-shocks while maintaining good road manners. To ensure the rear performance is on par with the front, Carli spec'd KING 3.0" 4-tube Bypass Shocks round off the rear.

For those unfamiliar, a bypass shock has external tubes with one-way check valves that are fully adjustable to allow users to tailor the amount of fluid that bypasses the piston/valving on either the compression or rebound stroke within the effective range of the bypass tube. Typically, there will be a tube surrounding the compression zone (at ride height) that will allow fluid to freely move around the piston giving a supple ride. Once a large hit is encountered, the piston will move upward closing off the port, thereby forcing all fluid through the valving which substantially increases the shock's resistance in this secondary zone. This acts as an internal bump-stop of sorts and gives tunable progression to the shock making it the perfect dual purpose setup.

Conversely, on the rebound side, Carli normally specs tubes that are oversized and deep in the travel stroke to allow a high volume of oil to bypass, ensuring the shock shaft comes out quick enough to maintain contact with the ground (doesn't get hung-up in the bump-zone after a large hit). As the shock extends and closes off the rebound tube, all the valving on the rebound side engages to slow the shaft as it reaches maximum extension, top-out. Simply put, the larger the shock diameter, the more capable the setup; the more tubes and "zones", the more adjustability; the larger the tubes, the more fluid can flow around the piston and the more valving you can run to increase the stopping power in the "bump-stop" or "top-out" zone.

Further, Carli finishes off ALL King shocks with shafts machined and polished from a solid piece of 17-4 stainless. Unlike King's standard shafts, there is no coating to wear off, weather is far less likely to hurt them and if there is a small chip, you can round the edges with emery cloth to ensure the seal housing isn't damaged as they're not brittle like the stock, hardened shafts. Note that all King shocks are built with a plated steel body. If subjected to inclement weather for extended periods, we recommend wrapping your shocks in 3M to provide a moisture barrier that's replaceable.

With a 3.0 diameter rear Bypass Shock, you'll get the addition of the Carli Fabricated Rear Shocks Mounts to ensure your day in the dirt doesn't end early thanks to a weak point in the factory rear shock mounts.

Your truck will sit 3"-3.25" higher in the front (year/cab configuration dependent) with 70% more suspension travel than the factory platform thanks to the taller, linear rate coil springs. These systems require the extended travel capability of the linear spring as the free-height of the multi-rate coils was too short to reach the droop potential.

As this is a high-performance, no compromise system, it includes the Carli Torsion Sway Bar and Full Progressive Leaf Springs (No option for extended sway bar links or add-a-packs). The Carli 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.

The Full Progressive Leaf Pack lift the rear 1.5-2" by replacing the entire factory leaf spring assembly increasing travel and drastically increasing comfort throughout the entire usable travel stroke at the cost of a 15% payload reduction from a standard 2500. This payload reduction can be supplemented back to factory 3500 SRW capacity with the addition of the Long Travel Airbags for the best of both worlds; ride quality and payload capacity/load control. But for those that tend to always have payload in the bed, such as a full time camper, Carli has the option for their Heavy Duty Leaf Springs for trucks with 1500 pounds in the bed at all times.

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 3/4" and back toward the cab 1/2". 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.

Wheel and Tire: This system will fit up to a 37"x12.5" tire with on 17"-18" wheels with 5-5.25" of backspacing. If considering Fiberglass Fenders, a 4.5" Backspacing on a 9" Wide wheels will fit up to a 37x13.5" wide tire. This system was tuned with 17" wheels on, 37" Toyo M/T at 40F/35R. 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.

IMPORTANT NOTES:
  • WHEELS Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5.75" of Backspacing on Leveling Systems
  • TIRES: 37", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 40F/35R
  • RECOMMENDED CONFIGURATION: Carli Leveling 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.
  • 2013 2500 APPLICATION: This kit will NOT fit a 2013 2500 as the driver's side rear shock mounts do not fit the 2013 models. Further, there is clearance issues between the shock tower and A/C lines due to the reconfiguration of the 2013 models.
