When lifting the 2011-2020 model Ford Super Duty 6" or more it may be necessary to extend the rear driveshaft to ensure adequate spline engagement at full droop of the suspension. While one option is to have a custom extended length driveshaft built, BDS Suspension is now offering a more affordable solution with their new high strength rear driveshaft spacer. Built from T6061 billet aluminum and CNC machined for a precision fit, this rear driveshaft spacer mounts between the driveshaft and rear axle providing the necessary driveshaft spline engagement. Longer hardware and thread locker are also supplied complete the simple install.
