ok, ive decided that SOMEDAY i am going to raise the k5 six inches with a suspension lift only. my question is about lengthening the drive shaft(s). do both need to be lengthened? is it smarter to lengthen them or just get new ones? i have to wait to get the length of the shafts till after i get the lift on right? thanx a lot! shaggyk5 aint nuthin in the world like A heavy chevy!!
