Does anyone have the factory suspension information for the impalas. I don't mean camber or caster I mean frame height and so forth. Or could someone direct me where I could find it.

The Factory Service Manual for the B-body contains all of the data points you are looking for. You really need to look at the book to understand the locations and how the measurements are made--much better than trying to explain here.

Try these threads:;f=16;t=000376

or do a SEARCH in the Suspension section--used the words "ride height" and you'll get 213 threads on the subject!

Wow--old thread back to life!

I wouldn't call it initiation--just enlightenment. Your question is very broad, and if someone responded with numbers, it could be completely meaningless, or misleading to you, in your quest to find the answer you're after.

The point is that "ride height" is established based on the RPO package for the individual vehicle. Giving you some numbers will not resolve anything without knowing more about your vehicle.

Overall, the range of variation is fairly narrow, so it's possibly not going to matter much in the long run.

The factory establishes ride & trim heights using a set of standards--the surface used for measuring, fuel load, tire pressure, etc, and, obviously, spring specs, determined by suspension RPO AND tire size, also set by RPO, creates variations of the measurements--change anything, and the info in the FSM is no longer 100% useful.
If you're still using OE-size tires, the info you gather from a set of measurements will be more meaningful.

It really WOULD benefit you to find a FSM, find the section in the manual with all of the information you're seeking, and you can see for yourself all of the variables involved.

I can scan the page(s) from the FSM and e-mail to you, if that will help....

I've been able to narrow it down within a quarter of an inch or so, and like they say: that's close enough for horse shoes and hand grenades.
