This configuration retains the factory 3 inch rear blocks combined with new BDS leaf springs to achieve a level stance. Select this option if your truck is equipped with factory 3 inch rear lift blocks to ensure correct u-bolt length.
Overview
This 6 inch lift kit with 4-Link and FOX 2.5 Performance Elite Coil-Over Conversion is designed for 2011–2016 Ford F250/F350 Super Duty 4WD Diesel trucks. The rear lift system retains the factory rear blocks and adds new BDS leaf springs to achieve a level stance. The leaf spring design operates in three stages: the primary three leafs function with no additional load for everyday ride quality; secondary leafs engage under moderate loads; and a bottom overload is engaged when the truck is fully loaded for maximum hauling capacity. This progressive setup maintains ride quality when unloaded without sacrificing payload capacity.
