Np205 lowering
I was wondering if anyone on here has ever dropped the case down say maybe an inch or so to accommodate rear drive shaft angle? I'm thinking I might want to do it to bring the driveline somewhat back in line. I'm thinking it would be as simple as spacers since it's divorced but haven't really looked much at it yet.

I too looked on Sky's site but found nothing. I bought my crossover kit from him(which is not all here yet). I'll have to look around I'm sure it's bit that hard to drop it some.

How much did you lift it? every situation can be different but generally speaking anything 4" or less on a highboy is not a problem, have you driven it yet to see if the driveshaft angle is going to be an issue?

Well I didnt drive yet I didnt get the other blocks in yet I'm just thinking ahead. The way it is now I have a 4" and a 2" block and 11 ply of springs and it works great. All I'm doing different is replacing the 2" block with another 4" since the front came out a little higher than expected.
I'm really only going an additional 2" in height but its pretty high already.

Well here is the driveshaft angle at the T case. I didn't get to take it down the road yet since the crossover arm is still in transit. I have a feelin this is going
to be a problem if I don't drop the t case some.

If this vibrates I think the easiest thing for me is to make spacers. I guess its a little different for you since yours is mated. I would think mine is probably a little worse of an angle since my driveshaft is shorter.
I really dont feel like moving the T case. I just want to drive it.

I have but they really only would have been necessary is I used a block that was straight. When I added the 4" block to my factory one it had the taper in it which made the pinion angle at the rear pretty nice.

No seriously though, I moved my rear axle forward 23". My trucks wheelbase is 6" shorter than a factory shortbed pickup and 6" longer than a full size bronco. I think the CV joint will fix my problem.

I have to agree with this. I did the rear shackle flip on my truck which angled the pinion more torward the transfer. I havent driven it at highway speeds but around town it completely got rid of my drive line vibration and it vibrated before the shackle flip. Im still wanting to do the CV joint on it just to be sure I dont have the vibration anymore.

Yeah but the CV joint would go at the Tcase end of the driveline. A CV joint uses two u-joints on a single end, the two u-joints combined together make the same angle by shareing the amount of angle. So, say for example your u-joint at this time is doing 20 degrees of work, a CV joint in the same set-up would have two u-joints doing only 10 degrees of work each.
