Carli 4.5" 2017+ Ford Super Duty Backcountry System Diesel
2017+ 4.5" Ford SuperDuty Backcountry System Diesel
The 2020+ Ford F250/350 Platform is the same as the 17-19 but they lowered the front 1″ and the rear 1″-1.5″ depending on the cab configuration and 250/350 designation. For this reason, the only change to the suspension systems will be the stated lift height. The 4.5″ Lift Systems from the previous generation, 2017-19, are now 5.5″ for the 2020.
This is a system designed for those who spend their time on the road and in the "Back Country". This kit will make highway driving feel great as well as equip your 2017 Ford Superduty with the essentials for heading off-road!
