im diving in to the start of another total suspesion upgrade but i need the part numbers for the 1LE springs (or ws6 springs for that matter) that would fit on my 91 Z28 all the way around. then it would be complete!!! :lala:

 

no such thing. they were the same as any other WS6 spring, or IROC.
rears are long discontinued, fronts are still avail.

 

This is from www.1le.net

Front coil spring (code CDB): 14029396
Rear coil spring (code NNL): 10018091

 

I've been trying to replace my IROC springs (85). The Federal-Mogual web site lists the fronts as part # 5662. The rears seem to be the problem. They're listed as part # 5665 EXC Z28 (82-86. Summit says 82-91, I believe). The variable springs are CC635.

Any help would be appreciated.

James, I believe you have my CD. If so, then there is a spring rate chart listing all of the part#s. One part# covers the top three front spring rates.

Thanx,andyZ28

 

Hey, Andy,

I'll check out your CD. By the way (this is a bit off topic, sorry), I'm beginning modification to my spindles for the 1LE upgrade. Where the tapping is concerned, should I simply use a tapered tap of the size you recommend? Also, any news about the rear brakes?

JamesC

 

A tapered tap will work just fine.

News concerning the Rear Brake Upgrade "RBU" will be posted soon.

Thanx,andyZ28

 

do you all think that 1992 z28 springs will fit my 1991 z28? i hope so cause i have the part numbers for those and i konw i can get them at autozone. but i know they upgraded a little bit for 1992
