Have a 4" lift and a spring over with a d30 and a 8.8 What should my driveline angles be? I also have a sye.
IIRC, this is a YJ?yes the lift kit came with new springs. And then I did the spring over.
I say ALL this....and you'll be fine!:thumb:IIRC, this is a YJ?
I think the best way to do this would be to mock it up with the perches bolted in, rotate your pinion, tack weld the perches, then remove the axle for full welding. People typically say a couple degrees (like 2-5°) below the TC output to account for spring wrap.
