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
Got the kit installed over the weekend. 1. It’s NIGHT AND DAY better than stock… when you spend good money on something (this is hands down the most I’ve ever spent on a daily driver) you are often let down with the result. Not the case here. I would do it again tomorrow.
The gang at CJC was awesome, answered all of my questions, actually listened to what my needs were had didn’t sell me anything I didn’t need or that I couldn’t add later if the result was sub par. Shipped the same day and everything arrived in immaculate condition.
Couldn’t recommend CJC or this Carli kit more - eleventy stars.
Back country with leaf springs.
The Carli stuff is top notch. Everyone at CJC is super helpful and responsive.
I did the backcountry with Deaver springs and Carli shackles.
Truck rides great. More like a 1/2 ton.
Deaver springs really mellow things down too. Find different bushings though. We’ve had these bushings in and out trying to fix the squeak with the suggested Pryoplex lube and they just squeak. So turn up your stereo, use a rubber bushing or skip the Deavers.
Absolutely love the full progressive deaver rear leafs. Softened the rear tremendously and really dialed the truck in now to match the front Backcountry kit. Truck is ok 18x9’s with 37’s, and rides damn near like a half ton now!
You will need to address the headlight level sensors with the new radius arms. Purchase a relocation bracket. We had a radius arm bracket that evidently had a bad threaded insert. Possibly weld spat but it cross threaded the bolt.
