I have been doing some searching and I have not found what I am looking for. I currently have a 91 Z28 with the F41 suspension. I am looking for some stiffer springs that are not much lower than my current ones. I was looking at the 1LE springs. are they lower, if so by about how much? From what I read I already know they are stiffer. Also if you have the part numbers I would appreciate it.

Thank You,
Steve

 

I am looking at my parts and illustration manual in the "spring section' and it only lists part numbers for fe1,2,3 and f41 suspensions, does not mention "1LE" setups. The stiffest rate and part numbers listed for these are:
(For 87-89 F-car, F41)
Front: Code BZZ, P/N 14029399
Rear: code NNB, P/N 10018092

(For 1991 F-car, FE1 & F41)
Front: Code BKR, P/N 14034238
Rear: Code NNB, P/N 10018092

(All P/Ns are service numbers, not production.)

I have no idea what the exact rate is, but those are the stiffest. Hope this helps.

 

ebmiller,as usaual you are 100% correct about the part #s. The 1LE springs were/are not available as a service part.I have seen my spring rate chart posted on here somewhere.The 99 front springs are the stiffest available.I have them on my 1LE equipped '82 Z28.

 

Hey Andy. what rear springs are you running? got a code?

I can't recall what mine are at the moment, but I'm pretty sure they're in the middle of that chart somewhere. I will probably go with Eibachs and move up to 17" wheels when I get around to it.

Later..
