Frequently Asked Questions (FAQ)

Why do these coils give a different lift height on 2020+ Ford Super Duty trucks? In 2020, Ford lowered the factory ride height of the Super Duty. Because these Carli coils are designed to achieve a specific, optimized stance, they provide 3.5 inches of lift on 2020+ models to reach the same final ride height that requires only 2.5 inches of lift on the taller 2005-2019 models.

Are these Carli coil springs designed for gas or diesel trucks? The CS-FLC-05 coil springs are specifically spring-rated for the heavier front-end weight of the Powerstroke Diesel engine. Using them on a gas truck may result in a stiffer ride and slightly higher lift than advertised.
