How much front driveshaft slip?

I'm still voting for the end all be all driveshaft from HAD. Hell I could pay for it just in the time of screwing around cycling suspension.

8 inches of slip and 42 degrees operating angle.
 
I thought we decided that articulating could extend the shaft more than hanging it (jumping) anyway.
 
Ah, I see you're point and agree. I'm like Martin and don't think most applications need crazy slips but there's definitely an error of measurement here.

What do you guys do with your rigs then?

I thought y'all all knew my junk just sits in the shop? :doah::dunno::thumb:

I'm a believer.

Looking at any truck that flexes worth a damn its clear to me that you can push a leafspring on one side down farther than it would go in just droop. The fact that the pumpkin isn't centered amplifies that problem.

I fully intend on doing some tests with my truck and reporting results...

Going fast and having the axle drop out quickly will achieve similar results in my head.

Maybe not quite as far, but with centerline of the diff not being out at the spring, articulation wont have the same effect on the shaft.

Sure I'd be willing to bet they're very close in usage of slip. I just think that one can get it to articulate to such that it's a bit more then droop.

I suppose it doesn't much matter as long as you've got a driveshaft that will deal with it.

Yeah. Im still interested to know.

axle wrap doesn't happen in the air......

That's a good thought. I wonder if it happens when you hit the ground though...
 
When you hit the ground, would that be called "wrap" or would "interference" be better? LOL

I'm so glad I'm going to link the front.....Linked the rear and have 1-1/2" slip with 16" of travel. :popcorn:

Hahaha, just kidding, I'm loyal to my leaf springs but I do have an upcoming build in the works that will be links front and rear.
 
So I have had many many problems with this. Not only in a square. But in every long travel leaf spring suspension with shackles in the back, in a front axle ( non centered) application.

The one situation where you almost always have problems are climbing a steep high traction surface. The front axle in forward movement wraps down not up, your front end is unloaded ( in the air) then it grabs traction and gets just enough traction to create axle wrap. And boom seperated driveshaft.

In addition in rapid transition i.e. jumping if you have very little spline engagement the driveshaft can bind that's can also result in serious issues.

In my suspension I have measured 7.75" of slip. I give myself an inch on compression and 2" on extension. So about 11" of travel is what I require. In 5 years of wheeling with a 12" travel shaft I have not had a single problem with the slip

I agree.....Last night I looked back at my receipts, I had them make my front shaft back in 12/03, it cost me $447.00. It's a long slip with the 1350 cv and a 1410 on the diff end. So it not the 42 degree, but I remember grinding it to make it work with a 8" lift. Since then I've lowered the lift and moved the axle forward. Anyway I've run this same shaft for 13 years with zero problems....So I think it's money well spent.
This aren't massive travel springs, I think they are Rough Country 1" or 2" I got for free years ago.
