Caster Correction Shim, 4.5" Lift - 1 Degree

- Ford Castershim 1.0 Degree (PAIR)
- For Use with 4.5" Systems for Caster Correction
- Fitment: 2005+ F250/350 4x4
Pricing: $75.00


When lifting the front of a Super Duty 2.5″, caster will be reduced by 1°. The 2° shim specified with our 2.5″ lift systems not only restores caster but increases it by 1° from the stock spec to ensure proper tracking with larger tires.

Our 4.5″ lift systems drop the radius arm pivot point 4.5″ to match the lift; thus, caster is maintained. We include the 1° shim to increase caster 1° over stock for the abovementioned purpose.

If running Carli Radius arms, it’s not necessary to run any additional caster correction as they increase caster 1°.
