Lifted leaf lengths???

OK, I got asked a question the other day and wasn't too sure of the answer... so.....
Are lifted leaf springs marginally longer in length (eye to eye along the curve)than stocko ones?? eg: are 50mm lifted springs longer than standard springs???
I know it's a basic question but wasn't sure myself.
Cheers.

how can it be not always. A lifted spring has more arch in it. they have to use a longer flat spring to achieve the lift so therefore the spring used is longer. I suppose you are referring to once the spring has been bent the overall leaf pack may be slightly shorter than the overall non lifted leaf pack

no, not always. they sometimes arch the crap out of a flat leaf that's the same length as stock. usually pretty cheap kits. they are the ones you see inverting shackles all the time, or that have really shocking shackle angles.

I used to think this also until I went shopping for lifted leaf springs and was told by a few suppliers that their main spring lengths are the same as stock.
I was told the reasons for it but I dont remember. I think it was something about them fouling the opposite way of inverting.
As badreligionau said.
I suppose thats why they make anti-inversion shackles
Old Man Emu is one that uses same as stock lengths but they supply anti-inversion shackles as well.
