Toyota SAS concern....

Should I expect any front driveshaft issues with my new setup: 5" TG springs and truck already has 2" drop hanger up front from Sky Manufacturing. I know length will be a issue of course but my main concern is angle still. Toyota ujoints max out around 40* and I don't see it being that steep. If anyone can reassure me so I stop worrying about it I'd appreciate it. I'll probably have Oliver's build my front shaft.
 
Shouldnt be too big of an issue. The Toyota has a pretty long front driveshaft. You can always limit the center of the axle at the driveshaft, if need be. This doesn't affect flex but will protect the driveshaft u-joints!

I have found this to be one of the easier SAS's to do because of no big drivesahft issues.
 
If @Oliver's is building it they can build whatever you want (high angle or not).

Too many unknown variable for anyone to answer this any better than what Scott did I'd think.
Are you turning the front axles? or trying to run them stock?

A driveshaft bolting up is one thing. It "working" is a totally different one
 
Right now galloways set my pinion at 0* but my caster is at 15*. A 10* shim will rotate my pinion up and put the caster at where it should be.
 
You are about to start chasing problems.
 
Nobody asked yet but are you running duel cases with a single case I have had to run high angle shafts
 
Make sure your upper ball joint are canted back a little, if they are straight up or worse canted forward it will drive like ass!
 
He's at 15* positive caster right now. Wayyyyy to much. 10* will bring the pinion up some and put him at 5* positive caster. (Also, no ball joints on that rig lol) That should square away the caster and pinion angle. If it will work from there, you should be fine.

Assuming that's 15* positive caster. (upper 'balljoint' leaned rearward). In that case, roll that pinion up as needed to better align the driveshaft, and still keep some positive caster. But not so much as to get zero or negative caster.

yea...what he said! LOL!
 
If you can get proper caster and a decent pinion angle...who's to say it's not "right"?
 
So get a stock rear shaft and have it shortened to run up front? I know that won't have a slip so I'd need a 2 piece rear shaft
 
Just have a shaft made and move on. Stock driveshafts generally suck ass anyway.
