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!

Customer Reviews
After leveling front end 2 1/2” and 1” in back I had a slight steering wheel wobble at 55-65. After installing shims made truck drive as smooth as butter. It’s a must do and makes a noticeable difference. Simple to install and worth your time.
Exactly was I needed
Made a massive difference in bump steer and overall steering feel in the truck. Highly recommended.
Installed a 2 inch front level on my 2022 F250 6.7. It was drifting while going down the highway. Added Carli 2° caster shims and now it’s back steering like it’s on rails. Easy installation. Highly recommend.
I was skeptical but I must admit it 110% resolved my steering issue. I'm more than happy, truck drives like a dream now
