Driveshafts' lengthening question (4" & 6" kit)

[ecablarn]

Hey guys, never seen many threads on this topic with a lift kit installed. What is needed for a 4" lift with one piece rear driveshaft? Same but for a 6" lift kit? Seems like there is a lot of travel but any jeep I used to own would have needed probably both shafts lengthened with a 6" lift kit. Thanks

Ranger driveshafts are fine as far as their length goes. This is because of them being longer, they don't get near as much of an angle on them, which keeps the slip-spline engaged better.

Only the two-piece rear shafts on '97down Supercabs usually needs to be changed to a one-piece due to vibration (not length).
