Configured for trucks with factory 3-inch rear blocks, paired with NX2 Nitro Series shocks. NX2 Nitro shocks feature 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 for the 2011–2016 Ford F250/F350 Super Duty 4WD Diesel is engineered to deliver a level stance while retaining full hauling capability. The rear lift system retains the factory rear blocks and adds new BDS leaf springs to achieve a level stance — select the height of your factory lift blocks for the correct U-bolt length. The leaf spring system uses a dual-rate design: at no additional load, the primary three leafs provide everyday ride quality; as moderate loads are applied, the secondary leafs engage; and when fully loaded, the bottom overload engages for maximum hauling capacity. This allows the truck to maintain ride quality when unloaded without sacrificing payload.
