1LE Shock/Spring help please

[funlman]

back in May I purchased a set of 1LE springs and shocks for my 98 formula WS.6 I checked out the part numbers and at the time everything was ok.

Now I need to use the 1LE shocks (Decarbon) and springs I can't find any proof that the front shocks or sprngs are really 1LE. Part description and numbers follow:

Suspension Kit 1LE
22132889 -- This is Rear 1LE Spring Springs - Coil Rear 1LE Rated 130lbs/inch - 180lbs/inch)
22077196 -- This is suppose to be a 1LE Front Spring but I can't find
any proof it is a 1LE spring.

22182505 -- Rear DeCarbon 1LE shock. 3644 R4 on shock
22182499 -- Front DeCarbon shock but cannot find part number
anywhere to prove its 1LE? 3648 K6 on shock I think these are rated 310lbs/inch
where other 1LE springs is rated 360lbs/inch

My problem is that if I can't find someone who knows if the front spring/shocks are 1LE also I am not going to put neither on my car. I can send the parts back but it's a pain to do that. I know GM has given their 1LE parts many numbers constantly changing and rechanging. I also know that sometimes stock and 1LE are the same, I am just confused. I am pretty sure I have 1LE stock on my 98 WS.6. I would look at my front shocks but car is at the garage getting body work.

Would it hurt my car to put this shock/spring combination on it?

What kind of ride and performance would or could i expect?

This is my daily driver so I do want a nice handling suspension.

Does anyone ave any idea what the front springs and shocks are and if they were truely 1LE at on time and just had part numbers changed?

What is the part number for the 3rd gen 24mm rear sway bar bushings?
Any help would be appreciated. I need to get this done as soon as possible car is at the garage now.

I have searched and read everything I could possibly find and still nothing. There has to be someone out there who can help me.

Thank you
eddie

1LE specific part numbers

This page is continuously under construction and all part #'s should be verified before purchase. These part numbers have been compiled from a variety of sources over time, and I believe them to be accurate, but GM has been known to change part numbers. If you find a discrepancy, please report it to chuckb@1le.net.

Jean-Marc Hurtubise was kind enough to look the thirdgen 1LE part numbers up. Click here to see them (large page).

Gary Garrison sent these in.

I was told that the only to verify the part number for a '93 1LE spring is to look at the 2 letter code on the springs on a '93 1LE car. The panhard rod was the same as a stock Z28 in '93.
