Lifted spring measurments

I have a question that I have not found an answer to regarding spring measurements.

Looking at the General Spring link .... I know that the stock spring measurements are 23 x 28 5/8.

Using the same measuring formula as the site:

Is there a link somewhere that show what the measurements are on “lifted” spring packs (not AAL's) for the different lift heights?
Has anyone ever measured their lifted "store bought" pack?

Quality leak packs " ie" deaver,national, etc are longer on the shackle end to give proper shackle angle. my understanding is RE packs are also longer. best bet is to call mfg to find out. hope that helps

I'm thinking the same thing....as I can only find the "stock" info.
