Mystery Eibach Lowering Springs
Hey guys,
I just found a set of Eibach springs in my garage #3801.201 and #3801.202. I can't find any information on these springs or how much they would lower my vehicle. The number is similar to the current F-body springs but I am assuming that this is an older set no longer available. Anyone know anything about them?

Those are pro springs, they are black right?

The standard pro kit springs have a number 3801.140, so these are different.

Re: Mystery Eibach Lowering Springs
probably and old part number or the number directly off the spring? The 140 number is for the whole kit, the other number for a front or rear spring. The pro kit has very dark gray almost black colored springs and it sounds like that's what you have

Re: Mystery Eibach Lowering Springs
True enough, the numbers I gave are off the springs themselves. I guess I could always find out the hard way though and just sorta slap em on.

Re: Mystery Eibach Lowering Springs
Did you ever find out any specs on those springs? I just got lucky at the junkyard and found some and I was wondering how much lower they'd be.

Re: Mystery Eibach Lowering Springs
I can't say with 100% certainty that the first 4 numbers on my springs was 3801, but I know they ended in .201 and .202 for my Eibach Pro-Kits which are supposed to be a 1 inch drop. I swear they dropped mine more than an inch though, but I didn't measure before replacing them to know for sure =/

Re: Mystery Eibach Lowering Springs
Thanks. I'm going to try and put them on this weekend or next weekend. I'll be sure to measure the before and after and I'll post the results!

The signature pic is with 90s Eibachs- thick spring isolator in rear.

Re: Mystery Eibach Lowering Springs
My drop was 1.5 inches. It took me a while to finally do the swap, but it's done
