Once, recently on another site. It was about stock height and was used in sand/desert. What's the benefit, smoother ride?

I was just wondering about something like that. To keep close to stock height but improve stock ride, and maybe lower it an inch.

If you "flip" the axle to ontop of the springs your gonna get atleast 3 inches of drop. Jeep guys do the opisite the flip them to below the spring to gain 3 inches of lift. As for ride its gonna be the same cause its the same spring.

No. I mean, what about a full, all around set of 4" lift springs, under axle. :)

Should be damn close to stock height, maybe a CH lower with a better ride. I was just day dreaming and was curios about it. :D

Figured a set of 4" springs might give 1" of lift, and 1" extra of compression on the front bump stops. :)

It sounds like a bunch of work that will not net you that much improvement. For one, are the 4" lift springs going to be softer than your stock springs? I have a hard time thinking they will be. To do the spring under you are going to have to cut and reweld the perches on your axle. Setting the pinion angle correctly, where and how the perches sit on the axle, will your stock steering still work with everything in a different position now, all needs to be taken into consideration, especially in the front. To much engineering to gain 1", IMHO.

I know your just day dreaming, so I am just offering the things I see you will probably need to work through. Not hard work, but work nonetheless.

If you actually really needed an extra inch before the bumpstops, could a 2.5" shackle flip and maybe a leaf pulled from your pack lift you up a little and improve your ride at the same time? Will it affect your towing?

Yah, I'm just trying to ask the unasked questions for the fun of it, lol. Just noticed a few vehicles that are set up that way at work and it got stuck in my head to ask about it. Rear springs on the Dodge Durango and many Jeep springs are under axle. And S10 trucks of course. Just exploring why that is and I am sure it is for better ride without gaining too much in height.

Always good to ask! I believe this conversion is fairly popular in the lowering crowd for the rear axle in particular. I would think were the axle is placed has more to do with the desired ride height of the vehicle it's being applied to.

If you have problems with spring wrap, this could be a good way to remedy it, as that it's specifically why the above mentioned vehicles run them that way.
