6 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (2011-2016) 4WD Diesel | Factory 3 Inch Rear Blocks | BDS Suspension

Select this variant if your truck is equipped with factory 3 inch rear blocks. This kit retains the factory rear blocks alongside new BDS leaf springs to achieve a level stance. The correct u-bolt length is determined by your factory block height, so verify your block size before ordering.

Overview

This 6 inch lift kit with radius arm and FOX 2.5 Performance Elite coil-over conversion is engineered for 2011–2016 Ford F250/F350 Super Duty 4WD diesel trucks. The rear lift system retains the factory rear blocks and pairs them with new BDS leaf springs to deliver a level stance. The leaf spring design operates in three stages: the primary three leafs function without additional load for everyday ride quality; secondary leafs engage as moderate loads are applied; and the bottom overload engages when the truck is fully loaded for maximum hauling capacity. This progressive setup allows the truck to maintain ride quality when unloaded without sacrificing payload capacity.
