Where the Performance 2.5” Long Arm System is more balanced, the tuning in the UnChained System is enough to put the build quality of the rest of the truck to the test and will ride a bit stiffer on the road than our other high-end systems; albeit, still much better than stock. At this level of suspension, customers should install a cage as the off-road capability far exceeds the capability of the truck itself. The Front Boasts massive, long-travel 3.5” King Shocks with an off-road oriented tune; the rear, 3.0” 4-Tube King 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 the purchaser (More on this in “The Details”).

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:

With the release of the 3" Long Arm, comes the Long-Arm equipped Systems. The decision has been made to discontinue the older, short-arm variation of the UnChained 3.5" in favor of a Long-Arm equipped, extended travel version at which you’re looking now. This system requires customers to cut off the factory control arm mounts in favor of the Carli Drop Brackets to house our 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.

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. For more details, see our article on wheel and tire selection and tire pressures:

System 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.

Torsion Sway Bar - Selection of the Torsion Sway Bar Replacement will not Require size selection as the entire sway bar assembly is replaced.

Leaf Springs - 37" Tires will fit with the above wheel specifications if the system is equipped with Full Replacement Leaf Springs and Control Arms.
