I am putting a 6" skyjacker lift on my 1980 Bronco the question i have will i have to make the drive shaft('S) longer?

 

[updated:LAST EDITED ON 03-Feb-02 AT 10:51 AM (EST)]Most likely not. It depends upon a lot of things, incl how much you lift the rear. Once you get it installed you'll want to put the frame on jackstands and allow the rear axle to go to full droop. Put the truck in N and spin the rear d/s, looking for any potential binding at the CV or rear yoke (this you'd have to fix w/grinding, not lengthening tho). Anyway, while it's like this observe the slip joint - if it's close to pulling apart you'll want to have it lengthened. There's no definite answer because Ford used various d/s styles over the years. I'm 99% sure the front d/s, however, will be fine.

 

I have '93 w. 6" superlift. Rear was lengthened 1" , fronts fine
