My brother runs an inch and a half drop.

Also a question/comment on the same subject.

Instead of lowering the transfer and losing clearance. And instead of an expensive sye. Why couldn't you angle the rear diff and extend the drive shaft?

You can angle the rear diff to some point. I wouldn't go past 6 degrees. You will put more stress on shock mounts and wear shocks out fast.

I run Iron Rock Offroad's 1.75" tcase drop at the moment.

Really, you can run any amount. It's not ideal, as I'm sure I don't have to tell you. SYE would be.

That doesnt really cure driveline vibrations. Might help, but its not the right way to go about it.

I prefer not to lower my driveline. Why lift it if you are just going to lower the exact center of your jeep?

Anyway i have seen up to 2 inch. I wouldnt dare go that low though. Sometimes you need to adjust your shift linkage, and in rare cases your fan might hit your fan shroud.

actually when angled toward the tcase your shortening the distance. so if anything you will need a shorter driveline
retubing a driveline costs about $100. retubing a stock rear driveline would be a waste of money
$200 for an SYE is not expensive at all. I installed my SYE and the stock front shaft fit perfectly in the rear. cheap spares for days, no vibes, and it was good to add the experience. totally worth it

Angling your pinion with a standard u-joint shaft is bad for it I was pretty sure. I thought it was with a double cardan you want the pinion pointed at the t-case.

Good point. Like ktm, I am not for tranny drops.

Diff angle should be parallel to the output shaft of the tcase when running a SY.

Not parallel to the drive shaft angle?

white you mean pinion angle right? pinion should be pointing directly at the output shaft and then tapped a couple degrees below that to make up for changes when accelerating

If you have a double cardan driveshaft yes.


With the stock SY driveshaft the pinion should be parallel to the tcase output.

Here's a link to explain it more:
