Default Quick pinion angle question

Hey guys, I’ve read a lot of threads regarding this but thought I’d ask anyways....

Should I change out the rear shims for 2* instead of 4*.

Pinion angle was at 4* after the SYE install with a t-case drop. Removed the drop and added 4* shims and here’s how it sits now.

Not noticing any vibrations on heavy acceleration, but everything I’ve read says to be 2* low for axle wrap. My tires are pretty bad on the highway, but I don’t think I’m getting any driveline vibrations.






About 3.5” lift front, 4” lift rear (measured from flares)

Don’t fix what ain’t broke?

Thanks for taking a look.

Nice ride.

Pictute of pinion would help me. I think your correct dont fix whats not broke. I also wouldn't worry to much about axle wrap. Point it straight to thr tcase and call it good

How worn in are your rear springs? If they're new, they will certainly settle some, pushing you into a negative angle.

Good point. They are about 2 years old with roughly 25k miles on them. I’ll keep that in mind if/when they start to sag.

Thanks guys. I think I’ll leave it alone.
