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.
These shims are designed for stock to leveled height trucks. Select 1.0* for 4.5" Lift Height Carli systems and 2.0* for 2.5" Lift Height leveling kits or stock trucks.
Please note, we do not accept returns on caster shims. If you have a question about them, please reach out to us!

Fit perfectly, fixes my steering issues. Caster is now in spec and truck handles much better.
These shims worked as advertised, I had installed another brand castor shim which also affected my camber settings, my super duty road like garbage. After I installed the carli shims, my castor was right where I wanted it, it also fixed the camber issue. I then did my own toe adjusted and am set at 1/16th toe in as recommended. Professional alignment too follow. I highly recommend the carli shims! A few tips, soak the old ones with penetrating fluid for a week or two before install and watch the carli YouTube install video from a few years ago on the castor shim install. CJC had them in stock and I received on the east coast within a few days…. Awesome product and awesome service!
I installed a leveling kit from another manufacturer but the caster was always off. This brought it back perfectly and the truck rides great now. Highly recommend. Dealer wanted $600 to fix. Save a ton of money and do it yourself.
The caster shims do as advertised, but they actually turned the axle back too far. I have a 2.5 level on my truck and ordered the specific shims for that kit. The truck does drive better but I’m not a fan of the drastic angle placed on the ball joints. Will be a temporary fix for now
The castor shims worked out great on my F-350 that I leveled with King Coilovers. Easy install. Running 37’s with no tracking issues.
Delivering top-tier ride quality starts with top tier parts and our Fabricated Radius Arms for your 2005 Ford Super Duty should be the starting point for your Carli suspension. Conceived through CAD-assisted engineering, the heart of the Ford Radius Arms is an internal network of X-Braces and gussets that lock all facets into one cohesive monolith. Incorporated into the arms are a formed channel that relieves tire rub on the Radius Arm, making room for even the most advanced and aggressive off-road tires and deep-offset aftermarket wheels. Also featured are fully serviceable 3″ Spherical Bearings that eliminate the kinetic energy issues associated with vulcanized bushings. Your factory ABS harness is kept out of harm’s way thanks to an included clamp, while your shocks are saved from top-out damage by our Quad-Wrap Limit Straps. Easily bolted on, the Fabricated Radius Arms replace your factory arm while using factory mounts and brackets. 4.5″ Lifts will require the Carli Radius Arm Drops, sold separately.
The Carli arms correct 1°-4° of caster at the axle mount ensuring ANY Carli customer can achieve the illusive death-wobble preventing 4.5° of positive caster.
These radius arms fit 2005-2022 Ford Super Duty trucks. They DO NOT fit 23+ trucks.
Fast delivery and very helpful. CJC was very helpful in making sure I got the right system and parts. Very quick to respond to any questions I had. Couldn't be happier. Thanks to everyone at CJC. Keep up the good work!
Arms are awesome quality. Truck rides amazing with the starter system and the carli radius arms. Suspension travels very freely and smoothly. Never going back to the factory arms. Also gained 2.5 degrees of caster with these arms without a drop bracket.
I am beyond happy. The truck rides very good
I did not follow the tire recommendation but it still rides noticeably better. I have not had it on a rough road but the one mile section into my subd
