Best LJ spring

I have been lookig at springs for LJ's for the past 4 hours and have not come up with a answer yet. I am looking at 3" coils and the rates or them. I've decided on AEV, Teraflex, And BDS. Any info as far as rate, actual lift height, how they ride and pics would be greatly appreciated. Happy holidays everyone

Actually they are Savvy 3" springs. Currie just so happens to make them for us. We are the only one that have and sell them.

Thanks,

BDS 3" : 158 200
AEV 3" :
Currie 3" : 155 195
RCD 3" : 180 180
ZONE 3" : 158 200

I had to leave AEV a message for the to call me back. It seems that the BDS and the currie are lower than I expected. They don't seem high enough for a LJ. The RCD and Teraflex seems pretty accurate. Does anyone know AEV Rate? Also, which one would be the best for a LJ with upgraded front and rear bumper and side armor?

I thought AEV was discontinuing most of their TJ/LJ stuff.

add up the weight your springs will have to carry, figure out the right height you want, then buy whatever spring has the unloaded length and spring rate to make that happen for you.

I scratched the 4" plans I had and 35s and just gonna do 3" with 33s. But how exactly do I calculate that? I want a true 3" height. What are the rates on stock 04 LJ springs with soft top?

We are currently looking at offering two different 3" rear springs. With so many different Jeep configurations we are finding that there is a need for a HD and standard rate spring. People with LJs or a bunch of stuff in the back really vary in weight distribution. Look for us offering two different rates and heights in the near future. I know Currie is going to be releasing their 4" springs with two different rates and heights as well.

And still progressive? Increase the light rate, heavy rate, both?
I don't want my LJ bottoming out on train tracks if I hook up a 3000# trailer. I figured I would go w/ your 4" to make sure that doesn't happen, but I'd prefer 3.
