These Carli full progressive rate leaf springs are a complete bolt-on replacement for your OEM springs and are designed for trucks with constant loads around 2,000 LBS in the bed, having a far heavier spring rate than the standard leaf spring, and operate with a much higher center of gravity, perfect for those who have campers or large tidy tanks. while delivering smooth, comfortable street-driving performance.

Part Number: CS-DFSP-19-425-XHD

• Progressive rate spring allows for smooth cycling throughout suspension travel for great on and off-road
• Axle Wrap & Wheel Hop Minimization: Reduces unwanted wheel spin and ensures better control
• Ensures optimal weight capacity and smooth street performance
• Includes the U-Bolt kit necessary for installation

• NOT COMPATIBLE with trucks equipped with factory rear air assist systems
• Because it has a far heavier spring rate than our standard leaf spring AND is designed to operate with a much higher center of gravity, Cari recommends that customers run the 2.5″ Remote Reservoir Shocks & custom shock tuning for optimal control and ride quality.

As the “Overland” Market has grown, and with it, the different in-bed camper segments, we’ve found ourselves adapting. We started with the TFL Truck. If you’re unfamiliar with them, The Fast Lane Truck is a popular YouTube truck-testing channel. We participated in the build of their 2020 F250 they equipped for their “No Pavement Needed” series in which they took a Carli Pintop equipped Super Duty across the country with a 4 Wheel Camper Hawk pop-up in the bed supported by our “XHD” leaf spring pack. We've done the same for the Ram Platform.

The constant 1,800lb.-2,000lb bedload required us to build a beefier version of the HD leaf springs. With this leaf spring and the added spring rate, we require customers to run the Pintop (King 2.5″) shock package for which we’ve developed a custom shock tune refining the overall ride, handling, spring rates and heightened center of gravity that accompany a rig modified as such. The result can be seen in the MANY videos TFL published featuring this bad-ass rig. Unfortunately, we do not have these tuning profiles for the Ram – we'll need to get a local truck with these springs in to develop this tune for the XHD, time permitting. If you have a local shock tuner that can dial these in, that would be ideal.

Availability on these, you’ll want to reach out to your Carli Retailer – be aware, they may not even know they exist. That said, you can expect a custom order to be in the 2-3 month range.
