Default Degree shims in the front

So a while ago I installed longer shackles on my jeep
Not super long but long enough to remove enough caster to have a negative effect in driveability
I know "they" say you aren't supposed to use degree shims on the front axle but why?
Has anyone done it and had any negative effects?

I personally would get shorter shackles and use springs to lift it.

I would too but I've already got 4inch springs and I don't want to stretch it with waggy springs or go spring over
I'm just looking for anybody with any solid reasons I shouldn't use the in the front

A degree shim is just a mini angled block

1 - New center pins
2 - New U bolts
3 - Shims 4'
4 - Install
Profit.

I see nothing wrong with doing this.

Well unbolted aren't a year old yet
Might need longer center pins
But that's my plan since nobody can give me a reason not to

The wedge will be part of the spring pack. Not a big deal. I've done a few of them. Do it and enjoy. It'll drive nicer too, just make sure you put them in the right way. Put them in wrong and it'll drive worse. Fat end to the front.

So let's see if I understand this. You put longer shackles on which gave a little lift and now your going to put a block that will lower lift? The shackle gave 1/2 the additional length because it is only lifting one side. The shim will lower spring pack by total thickness as it is in the center.

How much do you gain?

Shackles are probably 2" longer so that's 1" of lift
The degree shim isn't going to lower that much, more rotate

So, he'll lose 1/4" of height with the shim? See Jenny Craig.

If they were cast, I'd say No. I had a pair of cast shims break and partially fall out on the rear of my YJ.

Ya the aluminum ones are cheaper....but this gets driven in the winter occasionally so I don't see that as a good idea
Not over $15-$20

Only way I would do it is if they were made of steel. Then weld them to the spring perch.

Guy who runs silver lake with me had aluminum shims in front, they broke on the sand and he had to use his winch to keep axle in place back to camp.
