Configured for trucks with Factory 3 Inch Rear Blocks. Select this option to ensure correct u-bolt length for your factory block height. Includes NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends for increased strength, 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.
This 6 inch lift kit for the 2011–2016 Ford F250/F350 Super Duty 4WD (Gas) retains and builds upon the factory rear leaf spring system. The primary three leafs remain functional under no additional load, providing excellent everyday ride quality. As moderate loads are applied, the secondary leafs engage. Under full load, the bottom overload engages for maximum hauling capacity. This progressive setup allows the truck to maintain ride quality when unloaded without sacrificing payload capacity. The rear lift is achieved by retaining the factory rear blocks alongside new BDS leaf springs to achieve a level stance — u-bolt length is determined by the height of your factory lift blocks.
