yup they'll have to be lenthened unless you like dropping them out on the trail. My friend had a 6 and used a strap to hold in the front (like a driveshaft hoop) but had the rear lengthened. It worked for abit but it wouldn't trust it under serious load. It was right at the max
I beg to differ on that one. My buddy runs a 6" lift on his 'burb, and I'm running 5" lift on a longbed, both with stock d-shafts. No, netiher one of us has had a d-shaft pull out on the trail.

really?? Maybe it's the different brand liftI beg to differ on that one. My buddy runs a 6" lift on his 'burb, and I'm running 5" lift on a longbed, both with stock d-shafts. No, netiher one of us has had a d-shaft pull out on the trail.
Or they may have sent him the wrong one. I've heard it sat up higher than any 6" lift they had seen. 
Ok so i was wrong. I'll mark that on the calendar

I'd agree a K5 would have d-shaft problems, but yeah, Carl's (El Martillo on here) '87 'burb is 6" springs up front and 4" flip w/ 3" block in the rear with no problem. Then he smashed the rear shaft on some rocks.

I had a 2 piece rear on mine no problems there, front has been fine also.
No, he was just using it for a rock-slider, and it got a little dented.
OK, a LOT dented. He had it retubed and is still using it.

The only thing i had to do to my burb is grind off the little tabs on the front drive line.

I am running 5"-front and 6"-rear on my burb and have had zero driveline issues.

Ok so what's the big difference between a sub and say a regular truck blazer than?? I know a longbed a friend of mine had he had to have his lengthened
I've never ran more than 4" so i wouldn't know. besides the longbed i bought

Which did he have to lengthen, the front? Some might have issues with the front due to a hort trans/t-case combo like my K20 with th350/np205. The front on mine was a little short when I put in 6" springs, but I just unscrewed the seal cap on the slipyoke. It still didn't pull apart on the trail. The rears are fine due to the long wheelbase making a smaller angle change on the d-shaft. Blazers get a lot of angle change on the rear d-shaft when lifted, resulting in a bigger change in d-shaft length.Ok so what's the big difference between a sub and say a regular truck blazer than??

pretty sure he got both. Maybe the rear wasn't necessary but he didn't want to change how much splines was holding
either way i know he was supposed to get the front and never did. Just left it barely hanging on by a little bit of splines
