Axiom Supply 2° Caster Shim Kit – Ford Super Duty & Axle Swap Applications

If you’ve leveled your truck or swapped in a newer Super Duty axle, you’ve probably felt it—wandering steering, poor tracking, and a front end that just doesn’t feel planted. That’s caster loss, and it’s one of the most overlooked issues on these setups.

The Axiom Supply 2° Caster Shim Kit is a simple, proven solution to bring your front-end geometry back where it belongs. Designed to restore lost caster and stabilize steering, these shims make a noticeable difference in how your truck drives—especially with larger tires.

🛠️ Why You Need Caster Shims

Leveling your truck 2"–2.5" improves stance and tire clearance—but it also reduces caster by up to 1°, which leads to:

• Wandering at highway speeds

• Poor return-to-center steering

• Unstable handling with larger tires

On 2005+ axle swaps, the issue is even more critical since factory geometry no longer applies.

These 2° caster shims correct that loss and bring your alignment back into a usable range.

💪 What They Fix

• Restores proper caster after leveling

• Improves straight-line tracking

• Reduces steering correction while driving

• Stabilizes trucks running oversized tires

• Helps dial in geometry on swapped axle setups

🧰 Built for Real Use

These aren’t a temporary fix—they’re built for real-world driving:

• Daily driving

• Heavy towing

• Off-road use

• Large tire setups

The steel construction and zinc coating ensure they hold up against moisture, salt, and long-term wear.

🚚 Fitment
