spring rate of the front coils?

so i have been searching, but all the threads i looked at had different answers.

so, what is the spring rate of the stock coils and of the silver eibach coils from the toytec lift?

is stock around 560# ?
in the threads i have looked at, people say that the eibachs range from 620-650#

so what is it?

 

most aftermarket coils are 650

have no idea what the stocks are...

 

I forget but I remember SR5 coils were 540 and TRDs were 590? Yes the off roads and sports are different coils...

 

Eibach silver coils I believe are 620.

 

hah... thats funny. even for the few answers in this thread, its stated that the silver eibach coils range from 620-650. i guess i should just call toytec/eibach and find our for sure

 

The silver Eibach I have are stamped #600

 

ok... so i found the answers....


i called toytec directly and both the red and silver coils for the ultimate kit are eibach springs and are 600# @ 16 inches.

the stock trd springs are 540# @ 14 inches.

BTW, they are really nice and hepful at toytec. the lady i talked to went out of her way to answer all my questions

 

ya, i guess i coulda gone outside and looked at mine too

 

lol...Mine are laying on the floor behind me.

 

That's funny. I was told by Toytec that my silver Eibach/ Toytec springs were 620.

 

Yeah, mine say 620 on them.

 

hmm.... i will have to look at the coil and see what it says.

 

are the 620 eibachs a rough ride?

 

I would like to know this same thing as I'm looking to get a Billy 5100 kit. Just don't know what to get and where to get it for the best price. I hear the 620# springs ride stiff, though. So think the OME 590# springs would work great.

 

apparently my procomp coils are 550?? is that even enough? If im not mistaken, preload does not change spring rate right? @Chris 4x4 you seem to know a thing or two, do you have any input?
