Is This for You?

This system is for the 2011–2016 Ford F-250 or F-350 Diesel 4WD owner who wants Carli’s maximum-performance Unchained 3.0 system — 4.5 inches of lift with King 3.0 Bypass shocks. This is a professional fabrication build. If you have a gas-powered F-250/F-350, stop here — diesel-specific geometry. If you have a 2017–2026 F-250/F-350, stop here — see the Dominator 3.0 listing. If you want a bolt-on system, see the Backcountry or IFP leveling listings. If you want less lift, see the Backcountry 2.5 listing.

The Result

4.5 inches of front lift with King 3.0 Bypass shocks — maximum desert performance and front suspension travel on the 2011–2016 Super Duty platform. Purpose-built for serious off-road use while maintaining tow and haul capability under load.
