Carli's leveling full progressive rear leaf springs are intended to go on trucks with approximately 2.5" of front lift. These springs help to offer a significant ride quality improvement for the rear of your 2017+ Ford F250/F350. We recommend pairing these springs with Carli-tuned rear shocks, as they are custom tuned to match these springs.
OPTIONS
This leaf pack can be optioned with shackles and pinion shims. We highly recommend adding Carli shackles as they improve ride and articulation compared to the factory shackles, which limit what's possible with the Carli leaf packs.
The Pinion shims are not mandatory, but can help reduce driveline vibration if present. This has been a noted problem on certain F-250 trucks, so if concerned, we recommend adding it.
NOTE: These leaf packs DO NOT work with stock shocks from any trim package. Sadly factory shocks are too short, and the valving is significantly off from from what is required with these leaf packs.

Customer Reviews
I worked with Oscar on the build for my 2024 F250. Oscar was great, very knowledgeable, and was great at communicating with me throughout the process. My truck was in and out the same day, which is awesome considering it was a full Carli build. I have had numerous trucks built at different shops, including Kern County and Ventura County, and I HIGHLY recommend CJC offroad. I also love that they do the first responder discounts. I will definitely make the drive for any future work with CJC. 10/10
This was one of several mods installed on my F350 primarily to improve handling with the addition of a full-time slide in camper. Glad I went with the XXHD springs. Camper and equipment weigh in at about 2700 lbs and the XXHD springs are designed to work with a constant 3500 lb load. I don't think the XHD springs would have been enough spring for my liking. The ride with the XXHD springs and camper is smooth. Pintop Level Height system was also added to the front along with Carli Radius Arms, upper and lower steering stabilizers, the torsion sway bar mod, and 37 inch 13.50 Wildpeak tires mounted on Foundation wheels. These are all quality modifications/parts. Very satisfied with the results. I have about 3000 highway miles on this suspension/tire combination. The ride is smooth and comfortable. No side-to-side rocking when maneuvering which was a problem with the stock suspension. Feels like the camper/load isn't even there. With the stock suspension and camper, headlight aiming was a problem. These mods also restored a proper truck stance and the headlights are aimed properly. The truck feels good. I have not got off-road with this yet but I fully expect a satisfying experience there as well. Had CJC do the install and was very satisfied with their customer service and quality.
Cant state enough on how much better the truck drives, rides, and looks. Cant wait to take it to my local wheeling park to see how she does. A+ for CJC, they shipped it quick, and A++ on the quality that comes from Carli.
I was initially skeptical the Carli systems would be that good so I decided to just address the rear of my F350 because I had a cheaper kit installed when i bought the truck a few years back. With the Carli Full Spring pack and Backcountry shocks in the rear I couldn't be more happy with the performance. I'll be doing the full system up front and adding the air bags from them as well in the near future. I will say I've called CJC a few times and I have never been overly impressed...it has always seemed I was rushed off the phone and not given much conversation or direction about the specifics the individual packages. I ended up just doing my own research and then paying a vendor to send me something...I don't feel like CJC did an adequate job advising me on the system. When I called it would have been nice if they referenced the fact of the issue with the Front bolt on the driver side leaf or maybe ask what model I had and recommend that I need to buy an extra bracket from the load sensing system on my Limited. Instead I was just rushed off the phone and told it was easiest to just order online. Carli is a 5 STAR....CJC in my experience wasn't much more than a 2 or 3 star at best...which is unfortunate.
Couldn't be happier, it even fixed a highway vibration I've been trying to fix since I bought this truck. Rides like a caddy now even on the worst roads AZ has to offer.
