spring relocation

Hi Jared,

To answer your question, yes, changing the spring eye mount hole location changes the pinion angle.

What I recommend guys do is put the rear end in the car, with the springs and mounting plates held on the axle tubes by the U-bolts, but everything loose enough that you can move it. When you get it put together so it all measures correctly, throw some tacks on.

Anyway, don't worry too much; they make angled shims so you can dial in your pinion angle after you change the spring eye location.

I am in the process of doing a spring relocation and mini tub, removed passenger side wheel well today. Just started process today. I was just thinking about when I weld on the new spring perches, if I use the upper front mounting hole to mount leaf springs that will be one inch above stock, do I need to do any thing with the differential housing angle or can I just weld the perches in the same spot as old ones only 3" in to the center. Hope that all made sence! Didn't know if the one inch would make a difference on the pinion angle. Thanks Jared
