Carli Suspension Caster Correction Shim Kit 05-23 Ford F-250/350 Powerstroke

Carli's Ford Super Duty caster shims are one of the key ingredients toward the improved drivability that Carli's Ford Super Duty Suspension Systems offer. Caster is the rearward rock of the axle on your truck. Too little, and the front end wants to dart around like a shopping cart wheel or even death wobble. Too much and the steering feels heavy and only wants to go straight. Just right, and you have a perfect steering feel with predictable handling. 

Shims should be used as follows:

2 Degree: 2005-2023 Level Height

1 Degree: 2024+ Level Height / 2005-Current 4.5/5.5" lift with radius arm drops

Please note, we do not accept returns on caster shims. If you have a question about them, please reach out to us!
