Leveling your Ford Super Duty is one of the most popular upgrades you can make, but raising the front suspension also reduces positive caster. When caster is reduced, many owners experience increased highway wander, poor steering return-to-center, and a truck that requires constant steering correction.
Kryptonite 2° Caster Shims are engineered to restore the caster lost from most 2”-2.5” leveling kits, allowing your truck to achieve proper alignment specifications while significantly improving steering feel and straight-line stability. By restoring positive caster, these shims help your Super Duty track straighter, reduce driver fatigue on long trips, and provide more predictable handling under load.
Manufactured from heavy-duty steel and finished with a durable gold zinc coating, Kryptonite Caster Shims are built to withstand years of harsh weather and demanding use while maintaining precise alignment geometry. Whether your truck is a daily driver, tow rig, or weekend adventure vehicle, these shims are an essential upgrade for getting the most out of your leveling kit.
