Fits 2005-2026 Ford F-250 and F-350 Super Duty 4x4 trucks equipped with diesel engines.

Improve your Super Duty's suspension performance and stance with Carli CS-FLC-05 Linear Rate Coil Springs. These springs are engineered to address the harsh ride common in factory setups by utilizing a slightly reduced linear rate optimized for the weight of Ford diesel engines. Whether you are daily driving or hitting the trails, these coils provide a more compliant ride while maintaining the stability required for heavy-duty trucks.

To ensure long-term durability and resistance to sagging, every coil spring is shot-peened and pre-set. This precision manufacturing process allows the springs to handle demanding off-road conditions and heavy loads without losing ride height over time. The springs are finished in a durable black powdercoat for maximum corrosion resistance.
