How will lifting my truck affect the driveshafts?
Driveline correction methods are incorporated into virtually all of Superlift’s suspension systems. For example, our rear lift blocks are tapered to rotate the axle pinion upward to reduce driveline angle and eliminate vibration. Our replacement springs have a tapered degree shim attached, where applicable, to accomplish the same thing. Rolling the pinion upward also restores some shaft spline contact. More on driveshaft length – – generally, shafts must not be lengthened unless the suspension lift height is over 6″. Unless specifically noted, there is normally no need for replacement or lengthened driveshafts when the lift components are installed properly.
