I was thinking of something..

The other day, I was out looking at my truck, and something occurred to me..

I've seen a lot of people do shackle flips on the rear of their trucks to gain a little bit of lift. I was thinking, what if instead of flipping the rear shackle over, one were to take another set of rear front spring mounts, and bolt that sucker on instead? It's already pointing down, and I think by the time the shackle got bolted on and the truck sitting on it's own weight, there would be about 3 inches of lift instead of the 1 or 1.5 that nets from the shackle flip.

I don't know much about suspension geometry, so I don't know for sure if that would work out. 4 new holes would have to be drilled though..

Compressing the leaf spring increases the spring's length. So, doing two rigid mounts would place all the stress at the center of the leaf instead of distributing the load across the leafs' entire length.

But if you have the shackle in the rear like it originally does, that shouldn't be an issue because it could still cycle, right?

Ah, I see what you are saying... Hmmm. Yeah, it would work.

Btw, doing a hanger flip changes the configuration from a tension leaf system to a compression leaf system.

This is fairly common and has been covered in many "shackle flip" threads.

Using the regular rear hanger = Stage I

Using a front hanger in the rear = Stage II

Using a longer front hanger and a front hanger in the rear = Stage III

These are the three documented shackle flip methods I have read about in various forums.

It's not for my truck or anything... Mines staying at stock height. I was thinking for all the people who take the time and trouble to do a rear hanger flip.

Edit-
AK FORD GUY: oh really? I had only seen the rear hanger flip guess that answers my question then
