When lifting the front of a Super Duty 2.5", caster will be reduced by 1°. The 2° shim specified with Carli's 2.5" lift systems not only restores caster but increases it by 1° from the stock spec to ensure proper tracking with larger tires.
Carli's 4.5" lift systems drop the radius arm pivot point 4.5" to match the lift; thus, caster is maintained. Carli include the 1° shim to increase caster 1° over stock for the abovementioned purpose.
Note: If running Carli Radius arms, it's not necessary to run any additional caster correction as they increase caster 1°.
