Grind the stops off the CV and it will be fine. Mines been like that for years. And mines a low pinon design and I have never had a problem.

did it on mine man. ive done two that way and both have held up to 38s and a 383 playing with 475 crank hp. even in granny gear my original driveshafts held up fine. actually tore the slip part up but that's irrelevant to the cv joints
Yep. Grind em.
My guess is the stops were there to keep the driveshaft from hitting the ground if the front ujoint broke, and possibly catching on something and ruining your day..
But now that it's higher off the ground.....

mine took a little playing with to get it right. had to test fit and smooth some more. the 2nd one I did I took apart and put new joints in it. made it easy to grind while apart lol
Anyone have pics? I'm not familiar with this situation.
Scroll down to like the 12th pic and you can see the stop tabs on the cv. Killll them with grinding

Interesting. I don't think I have those on my 83. I'll double check later.
Just be careful how far you take it.
I started with grinding the stops. Next thing I know I needed more, so I ground a little more. Before I knew it I had ground the $h!t out of the yokes and even ground the pivot ball in the center some
It died in short order
With factory springs you probably wont need that much more flex in the shaft but with 52s you're really pushing the limits on what a stock dual cardan joint can do.

What do you have under the front?? It looks like a HP Ford with driver side drop and the the shaft looks to be a passenger side drop from the pictures. Or it this an optical illusion????Ok here is the drive shaft still attached to the NP208.
I pulled the drive shaft and I will post detailed pictures of the stops on the cardan before and after as I go. $200 is a bit much to fork over when there is a possible free solution.
How I hadn't already broken it is beyond me. It had to be nearly maxed out on flat ground connected to the old 10 bolt. I twisted the crap out of it a few times
yup ground mine off when i had a hellova lift.. 13" leafs... now sitting @ 6" they are ground and plenty of room
If you wanna get fancy and follow that spring cycling thread I posted. You can figure out every length and angle needed for driveshaft to work with your springs.
Mine is ground to work at full droop and just a few degrees past.

you should be fine grinding down the spots you have circled. There are also a couple up inside the H-yoke that can be ground down as well but you have to take it all apart.
I would grind what you have circle liberally and call it good. If you need more flex than that offers you need a new shaft but I don't see any reason why you would with stock length front springs and a hp front end.

You should be fine. I would be running the same drivetrain setup in my 92 with the drivers drop np241 and hp ford axle. I'm running 52" springs up front and 7-8" of lift with a stock 1990 k5 blazer front driveshaft and grinded CV stops.
