Ok I have had this set for 7 months now and I still havent put them in my car. I purchased them for my 99 but now I have a 02. The part number is for 95-01 Maximas. Here are the numbers on the springs.

Front Springs
44352
0700.250.0450

Rear Springs
41148A
GC180.64.61

Thats the info on the springs. If you help me I would appreciate it a lot. I just dont want to put them on my car and then have my car bouncing everywhere.

Thanks in advance,

Chris

 

The first one you listed (front) is a 450lb spring with a 7inch length and 2.5" diameter.

The rear spring is in some code that means nothing to most of the world. My ground controls are the same way. The front uses regular Eibach nomenclature for the spring specs, and the rears are some nonsense that no one knows exactly what it means except ground control. If you call them they will not tell you because they claim it took months of research to figure out the "optimum spring rates". If I were to guess at my rear spring rate id guess its in the 325-375 range. Yours probably is too.

 

the older springs i dont think told directly what the spring rate is... I'm guessing if you have 450 in the front then its yea 300-375 in the rear

 

Thanks for the help guys.
