How will lifting my truck affect my driveshafts?
Driveline correction methods are incorporated into virtually all of Superlift’s suspension systems. For example, our rear lift blocks are either tapered or flat, depending on application, to address driveshaft angle. 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. Sometimes the blocks’ pins / holes are offset to address shaft length issues. More on driveshaft length: Generally, shafts must not be lengthened unless the suspension lift height is over 6″. Check out the Installation Notes in your vehicle’s section of the online catalog. Unless specifically noted in the product text or installation notes, there is normally no need for replacement or lengthened driveshafts when the lift components are installed properly.
