Carli FORD Super Duty 05-16 Unchained 3.0 Bypass 4.5" Lift Suspension System

USA MADE // Carli is committed to production in the USA. Every single Carli Product is American made and sourced, down to the tape and boxes themselves.

CUSTOM TUNED // Unlike your average lift, Carli Suspension uses only custom tuned shocks. Each shock package goes through months of testing, development, tuning, and valving. The tuning on the unchained system is able to handle the biggest hits and most aggressive driving you can possibly do. Jumps, whoops and high speeds are no match for this kit.

RADIUS ARMS // Hand fabricated and welded in California with the highest quality joints for improved flex, these arms are a high strength control arm replacement. These arms feature a fabricated notch making it possible to clear 37’s on a wider range of wheels.

Meet the Unchained system. Designed and tuned as a no-compromise on and off-road suspension, this kit starts with the biggest shocks that can safely fit without extensive modifications. Simply put, there is no bolt on Ford suspension system that is as capable as the 4.5 Unchained.
To maximize the full potential of this system, it comes standard with our Full Progressive Leaf Springs and Stainless Shock Shafts from King for long life in hostile environments. The Unchained System was designed for skilled, experienced drivers with considerable seat time in a heavy-duty vehicle driven in offroad environments. This system is NOT for Novice Off-Roaders and we recommend a full cab roll-cage be installed prior to searching out the capability of this system. All the above performance is packed into a bolt-on (fully returnable to stock) suspension system.
This system fits Ford F-250 and Ford F-350 4x4 trucks from 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016.

Was looking for something specific- gave them a call and was able to order it up, even though it was not on the website.

Boyfriend and I both have a set of the 2.5’ whips for our jeeps and use them every chance we get. They look for show and work even better for light in camp and on the trails. They bolt up similar to a radio antenna and have a quick release feature that we have never seen before but absolutely love. Definitely top 5 favorite accessories we’ve bought for our jeeps, and customer service is just as great as their products!
