Good morning Gang. I have a quick question. My 73 Scamp rides like a dream right now, however, I would like to raise the back end about 2-3 inches. Have kicked around air bags, air shocks, coil overs, etc. Problem is, I don't want to stiffen up the ride. I was wondering if any of you have ever lowered the rear axle to below the springs rather than on the top as designed. In the custom truck world, one of the easiest lowering tricks was to flip the axle to above the springs thus gaining about 3 inches of drop. Wondering why I couldn't do the opposite to gain some height on my Scamp? Thoughts????

That will probably raise it much more than 2-3 inches. If you measure the center line of the axle to the spring perch and than add the thickness of the spring pack to that you'll probably be closer to 4 inches.
 
That will result in about a 6-7" lift in the rear. Yeah, go ahead. We want pictures.
 
Could you flip the front leaf spring hanger? Maybe have a spring shop add a leaf or two on the bottom that are only a few inches long just to add height and use longer U-bolts?
Flipping it would probably raise it 3.5".
3" tube + maybe a 1/2" for the perch?

Trust me, it's gonna be more. Imagine from the axle center line to the leaf spring pack. That's probably close to or over 3". Now, imagine flipping that to the under side. You have the 3" from the axle center line plus "however" thick the spring pack is, because now you're on "the other side". He'll get a good 6" or so. I've done it on trucks a good much and it's always around 6-7". It's a big difference.
 
Wont B body or SS springs, two of one side or the other achieve that? I would be worried about the off set flipping the diff. It would place the yoke the distance of the offset to the driver side, thus doubling the distance of the offset from trans to diff.
 
I believe he's just talking about moving the spring perches from the bottom of the axle tube to the top, not flipping the whole rear end up side down.

A flip is where you weld spring perches on the opposite side where they're at now. You don't flip the rearend. Just move the spring perches from the bottom of the tube to the top. The reverse of this is commonly done with the lowering of a pickup, moving the springs from the top of the axle to the bottom, thus, lowering it.

Well that takes the left handed monkey wrench out of it. I was thinking all sorts of problems with the yoke on top and no oil on the pinion. All this time, I thought they actually flipped the housing

Yes that's correct. I don't see where anyone assumed otherwise.

Yeah and THAT axle is not even flipped. They'd have gotten another 6" if they had done that. lol
 
Thanks everyone for the input. I wasn’t expecting such odd input. I guess there are more people that don’t know what a rearend flip is. Lol I was asking to see if anyone had done this before to see the possibilities. Ill see what my options are from here.

Odd input? It’s an odd question. There’s a reason no one had done this before on one of these cars. It will not be a 2- 3” lift.

Like RRR said, it’s gonna be a lot higher. If you have 3” axle tubes, flipping the rear perches underneath will start as a 3” lift. Then, you’re going to add the height of the perches themselves. Then you’re going to add the height of the spring pack. It’s gonna end up being at least a 5” lift, maybe more like 6”. Even if you have a 7.25” with smaller tubes it’s still gonna be 4-5”.

That’s not a little rake, it’s not even a lot of rake. It’s a stupid amount of rake. Like a truck with a 6” lift at one end and stock at the other. You’ll shift the CG way forward, which will put a bunch more weight on the front suspension. That will completely bottom out the front suspension with stock torsion bars. The rear being that high will also add a TON of negative caster. The car will feel like driving a shopping cart. And forget roll centers and handling.

Sure, maybe a couple people didn’t know what you were asking because they’re not familiar with lowering trucks or 4x4 suspension. But the rest of us are just confounded as to why you’d even consider this.

It’ll be higher than that.

We know exactly what it is, and the lift will be LOTS. The difference will be the total of the spring pack thickness + the diameter of the axle.
