Does anyone know a site/page that lists the spring rates for each suspension manuf.'s coil springs?

I don't know of a site, but I did some homework on the subject a while back:

Stock fr:410lb/in---rear:275lb/in

Most manufacturers 2" lift is the same as stock

4" lift fr:560lb/in--rear:stock
6" lift fr:580lb/in--rear:stock

Rancho never gave me a straight answer on spring rates.

best fullsize springs out there are the fabtech 2wd coils, just get ones 2" bigger than the lift you are going for. i.e 6" lift requires the 8" coil
aren't those coils progressive rate too?

NOBS are you running 8" ranger coils? I guess the spring rate would be considerable less and should provide more flex.

NOBS, how did it work out on Evilbronc's truck? What is the ride like on the trails? How's the flex? I've got the TTB now with a 6" skyjacker class II, but really want more flex from the front end, and may go SAS with some soft coils. Sounds like evilbronc has done what I am considering doing.

Do you know what the spring rate on those 8" ranger coils is?

Your ttb won't flex much better with coil swap.Your brake lines and shocks will limit as is.Undo your shocks and see how much more droop you get.

If you go sas with the ranger coils you'll have to make a lower coil mount similar to the ttb mount. Never measured the rate,but we did a makeshift ramp and it worked pretty good,considering the 78/79 radius arm setup/non wristed.
