8.8 pinion angle(i know)

I have to ask because I have not seen this one answered yet,I'm ready to install the 8.8 for a test fit and to set pinion angle before final welding,I will be running my stock ds for a while till I can buy sye and dc driveshaft I have full adjustable long arms so what angle should I shoot for that will work for the mean time on a 5.5 lift.

How long you going to run your stock ds?

If it were me I would set the pinion angle close to what it would be with the sye kit.

It'll be a while before I can justify spending more money(wife says I have to many parts laying around as is).im thinking with my lift I should be alright at 12* since its fully adjustable,but that's why I started this thread to get the pros opinions .

You will blow u joints and adapters if you don't stick to stock angle. Ask me how I know. Do the SYE now and set the right pinion angle. Or run stock shaft and stock angle. Nothing else, you also get a humming sound. Thats the U-joints saying they're unhappy.

I went to about 13* when I did my 8.8. Not sure what the "exact" numbers should be. Isnt your pinion angle supposed to be an exact opposite match your T case output angle? Or maybe I read that wrong somewhere.. ZJ's have a longer wheel base (longer driveshafts) so driveline angles arent as severe as with say, a TJ

when using a conventional drive shaft the output angle at the tcase should match the input angle on the axle.

With a sye kit and using a dbl cardan driveshaft the pinion should be pointed right at the drive shaft

U making your own brackets? I had the IRO kit took an hour to weld up and the instructioms were super easy. Didnt even test fit: just welded it up and bolted it in fit perfect

Installing the SYE then checking your angle is the right way to go about it. Then you can set the coil buckets and tracbar bracket level..

I'm at 4.5" and will be installing an XJ D44 into my rig here soon. When I had the bracket kit installed I set the pinion at 10* and leveled the buckets, i'll probably be just a few degrees off.

The coil buckets are 2 degrees forward and trackbar bracket is straight up.
