Unleash the potential of your vehicle with a more comfortable ride, increased suspension travel, and improved handling on and off the road.

Smoother Suspension Cycling

By replacing your existing leaf springs with the 2017-2024 SuperDuty Carli Full Progressive Leaf Spring Kit, you can expect a softer unloaded ride, a significant increase in suspension travel, and impressive capacity as the rear end compresses, engaging all the springs. This translates to a more predictable and supple ride, whether you're cruising on the highway, venturing off-road, or towing heavy loads. This spring pack is engineered to your Ford truck's exact specifications, ensuring optimal performance and supporting up to 15" of wheel travel. The center-pin is relocated to accommodate tires as large as 38" (37" recommended), and it levels the rear perfectly to match 4.5" front suspension systems. With this comprehensive upgrade, you'll experience smoother suspension cycling in all driving scenarios, giving you confidence and control wherever you go.
