2017-2026 Powerstroke XHD Leaf Spring Kit w/ 1" Rear Lift (CS-FFSP-LVL-17-XHD)

Note: NOT designed to run unloaded - 2,000 LBS constant load

These springs are perfect for those who have campers or utility boxes, or a constant 1,800- 2,000-pound bed load, as such setups require a beefier, more robust version of the regular HD springs. These springs will also need to be accompanied by Pintop (King 2.5″) shock package to further refine overall ride handling, spring rates, and a higher center of gravity.

As the “Overland” Market has grown, and with it, the different in-bed camper segments, we’ve found ourselves adapting. The “HD” spring can be pushed from it’s recommended 1,000lbs. but not by much. Plus, if you’re spending that kind of money on a custom spring pack, why settle for “almost” correct? 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.

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.

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 which matches a normal (non-COVID) lead time on the matching, custom tuned King Shocks to accompany them.
