Configured for trucks equipped with factory 3-inch rear blocks. Select this option to ensure correct u-bolt length when retaining factory rear blocks alongside the new BDS leaf springs.
Includes NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends for increased strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.
This 6-inch lift kit is designed for 2011–2016 Ford F250/F350 Super Duty 4WD gas trucks. The rear lift system retains the factory rear blocks with the addition of new BDS leaf springs to achieve a level stance. The leaf spring design operates on a dual-rate principle: the primary three leafs remain functional under no additional load for everyday ride quality; as moderate loads are applied, the secondary leafs engage; and when the truck is fully loaded, the bottom overload engages for maximum hauling capacity. This setup allows the truck to maintain ride quality when unloaded without sacrificing payload capacity. Choose the height of your factory lift blocks during configuration to ensure the correct u-bolt length.
