Ok these are the spring rates I am buying:

Front:
200.64.58

Rear:
204619-1

I am trying to figure out what these are in American units. Thanks in advance!

 

Since the GC springs are just Eibach springs made to GC's specs you can discern the spring rate and dimensions. Eibach labels their springs in the following order:

Length . Diameter . Spring Rate

They may come labeled in either English (inchesx100, inchesx100, lbs/inch) units or Metric units (mm, mm, N/m)

The conversion from Metric to English is (/25.4, /25.4, x5.7)


200.64.58

8" , 2.5" , 330 lb/inch

the rear number is a batch number. you have the wrong set of numbers.

 

Wow excellent post, I always wondered what the label on the spring was. Thanks.

 

Thanks for the help. He sent me pics of the springs, and those are the number off it. I will try and get the correct numbers for the rear and post them up.

 

I'm a bit of a noob when it comes down to this but what does the 8 inch and 2.5 inch represent

 

eibach race springs have different lengths, inner diameters and spring rates.

Length . Diameter . Spring Rate



they WILL NOT work on stock shocks without a proper perch, like ground control kits, or a threaded body shock that has its own perch.

 

Ok so the rear springs are labeled as follows:

180.64.44

American units please. Thanks

 

did you ever learn to use a calculator? please?

 

^^yeah he couldnt have made it any simpler for you. The burden of knowledge is a heavy one, eh Tyson?

 

Oops I didn't see that conversion factor mentioned above. It's all good now.

 

this is awesome .

 

if you feel even lazier still you can type the part number into google. 9 out of 10 times it pulls a post somewhere asking the same question about a spring rate number.
