Product Description

The Carli Suspension CS-FCASTERSHIM-45 is a precision alignment component engineered for lifted Ford F-250 and F-350 Super Duty 4WD trucks (2005-2024 model years). Whenever the front suspension is raised - especially in 4.5"-5.5" lift systems - caster angle can be reduced or mis-aligned, causing handling issues such as wandering steering or uneven tyre wear. This shim corrects the caster by +1°, restoring optimal front-end geometry for improved stability and steering feel.

This part is perfect for enthusiasts who have installed aftermarket lifts, big tyres or heavy-duty accessories on their Super Duty truck and want to ensure the best steering behaviour under load and off-road conditions. It installs in minutes by replacing or adding to the factory mounting interface, retaining the original mounting points and alignment geometry.

Fitment is confirmed through 2024; 2025 coverage is unconfirmed at time of listing. Before installation, confirm that your truck's front suspension system corresponds to a 4.5"-5.5" Carli front lift or equivalent setup as this shim is specifically designed for that geometry.
