Suspension lift for K30

[Bulldog]

Do you not already have a dual cardigan in there? Most stock Chevies do. 2 u-joint in the rear, 1 in the front. I have 6" lift on my blazer and that driveshaft, without clearancing, and a Dana 60 front does fine. Granted, I had to get the proper length shaft after the lift, but since then it's been fine.

Yep, Google is my friend. I understand the terminology now. I was thinking multiple cardan, like CV joints on both ends of the shaft.

Can the clearancing be done by at home or should a machine shop do it? I imagine a grinder or carbide burr would do the job, but then do you have to worry about balancing?

Would a transfer case drop work well enough with a 5.5" lift not to have to lengthen the shafts?
