So, I'm finishing up the install of the new track bar, UCAs, spacers, adjustments, shackles, etc.
After much web research, I extended the front axle an additional 1" using the upper and lower control arms. Put the front wheel more centered in the wheel well without taxing other components ... track bar still rotates and coil spring is closer to vertical. My question is the rear leaf suspension.
Many times I've seen spring perches and bolt plates that will accommodate moving the axle 1" forward or 1" back from the standard location. One can assume this can be down without doing any taxing of the rear components as well.
Not one to assume too much where safety and mechanical reliability are a must, is that a valid thought? Just because I've seen the parts does NOT mean it is a good idea, that much I have learned.
Thanks for the input!

Offline I don't see much reason to move your rear axle/springs. Most move their fronts out to compensate for the increased lift and the fact that it shortens your wheelbase and moves your axle back. I don't see the same issue with leaf springs, your rear axle should still be centered.

Actually John, it did move the rear axle forward with the frontmost edge of the rear tire now under the rocker panel. Granted, as the suspension compresses it will move back as it rotates upward.
Just like the front CAs, the distance of the axle pin to front spring mount is about 23" ... so where the front axle moves rearward with the lift, the rear axle moves forward almost the same amount. I'll see if I can post a pic a bit later as I'm in a meeting and should be listening.
