Carli Commuter 2.0 System, Base, 3” Lift, 2007-17 Jeep Wrangler JKU

The Carli Commuter 2.0 system is designed for the optimum on-road and around-town ride quality while still being capable of some light offroading. Perfect for those wanting a great ride without breaking the bank.

Carli's focus in building this control arm kit was to have the best product on the market. Our control arms are 1/2 longer than O.E.M and are built out of extremely stout box tubing. The box tubing's advantages over round tubing include a reduced control arm width while allowing the tube to be offset inboard for added tire clearance. Expertly welded to each square tube is a spherical joint that is fully serviceable and rebuildable. Having these spherical joints on each end eliminates the kinetic chatter caused by rubber bushing style set ups, in return creating a smoother ride. These control arms are finished off with a Satin Black powder coat to ensure long term protection from corrosion.

When lifting the front of the Super Duty 3 – 3.5″, the factory caster is reduced by approximately 1.5°. For the 2020-23 Super Duty, we provide a 2° caster shim which is enough to restore this caster and add a touch more – unfortunately, this “touch more” is rarely enough for proper tracking. This leaves us recommending our Adjustable Radius Arms proven to add an additional 2.5° of caster (when maxed). Combining the Carli Arms and 2° shims results in a Super Duty on 37″ tires that holds a lane, and returns to center after a turn, better than a stock truck.

Enter the 2024 Super Duty – Ford made ONE change to the platform… They added an outer axle-mounted guard to prevent debris from entering the outside axle tube. The issue is in the functionality of the ball-joint mounted caster shims we provide in our 05-23 Super Duty Systems to correct the caster. These shims don’t affect the axial position of the axle, but rotate the knuckle/upper ball joint position rearward relative to the axle’s outer “c” to increase caster.

Given the tight proximity of this debris shield to the axle tube, any caster shim over 1° will cause contact. Unfortunately, these trucks come with low caster from the factory compounded by the loss of caster from lifting the truck (radius arms tilt the axle forward – reducing caster – as the axle travels away from the frame); we had to figure out a solution.
