Description
Carli set out to make the ultimate 2.5" suspension system for the Ram platform when designing the 1500 Performance System. It boasts 9" of front suspension travel and 12" of rear suspension travel with only 2.5" and 1" of lift respectively.
At the core of the system is a set of Carli specific King 2.5" shocks with Carli's custom pistons, lengths and shim stack tuning that are optimized to maximize ride and travel. Several limitations and mounting constraints resulted in a coilover that's NOT adjustable for more lift height. The 600lb rate provides exactly 2.5" of front lift on the Hemi and 2" on the EcoDiesel (non-Rebel). Another 1/2" turn of the collar will result in coil bind.
This added down-travel of this system makes the Carli Control Arms a MUST, so they're included in the Performance 2.5" System to avoid topping out on the factory ball-joint upper control arm.
In the rear, Carli designed a multi-rate coil spring to maximize suspension travel while providing a supple yet predictable ride on and off the pavement. This multi-rate coil provides 1 -1/4" of rear lift on a Hemi truck and 7/8" on an EcoDiesel. Carli also provides extended sway bar end links to maintain the factory rear sway bar through the extended range.
We recommend 18x9, -12mm Offset (4.5" backspace) with a 285 or 295 tire for minimal trimming. A 35" x 12.5" like shown in the photos will fit with slightly more trimming.
Cold tire pressure should be kept at 35psi in the front, 30 in the rear for optimal ride quality when unloaded. Stock wheels and tires WILL fit this lift but larger tires will NOT fit on stock wheels - they're too offset and will rub the Carli Control Arms.
