How to tell Eibach spring rates??
I am talking about the Eibach springs with 2.5" diameter used for coilover/coilover kits.
There is a number on the spring, and I am thinking the last 3 numbers are the rate. Anyone know for sure? TIA |
One number is length (in mm) and the other number is rate (in kg-mm).
I forget what the exact format of the numbers, but it's pretty obvious once you see the groupings.  You have a spring around handy? -Ted |
As a general rule I just multiply the metric spring rate by 56 and that should be really close to the standard units of lb/in.

You can see the number.
For example, 0800-250-0450 0800 means the free height , 8 inch. 250 means inner diameter. , 2.5 inch 0450 means the spring rate , 450 lbs per inch |
Thanks! That is exactly what I thought, just needed confirmation.

Not all Eibach Springs from GC are written in "0800-250-0450" that format. I got some that the numbers were all weird, and I didn't know what they meant...After reading ReTed's post, I am thinking they were probably in kg/mm. I wish I had my extra springs here with me so I could tell.

Well, if anyone is interested, I have a pair of 2 1/2", 7", #375 Eibach springs I am looking to sell.
PM me if you are interested. |
My FB Eibach's from GroundControl are "GC150.64.53" So is that 5.3X55.88=296 Spring rate? I wasn't sure if I received the right ones or not.
Thanks |
