CARLI 23+ FORD F250/350 4X4 RADIUS ARM DROP BRACKETS - 3.5" LIFT

Designed for perfect fitment on the updated 2023+ Ford Superduty trucks, these drops will correct geometry with 3.5" lifts. The 2023+ Super Duty introduced some new challenges, specifically pertaining to caster. The steering assist and Ford’s 1° – 3.6° allowable caster range seems to work alright for those equipped with stock, relatively low-mileage Super Duties but, once a lift or oversized tire enters the equation, the handling at this low caster specification leaves us wanting. 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. The Carli Radius Arm Drops for 3.5" lifts were designed to fix this problem once and for all. The bolt-on design is a simple and easy installation that will provide the necessary increase in caster at a lower price point than installing the full Carli Radius Arm System and are compatible with stock OR the Carli Adjustable arms.
