Does anyone know if moog has any of their coil spring specs listed on the web somewhere? I'm looking for front springs for a 69.

To the best of my knowledge, they do not have specs listed online. Most autoparts stores have a Moog catalog and the specs are listed in there. When I was looking for rear springs for my 1972 Elky, I went to my local auto parts store and they let me look through the catalog until I found the spring that I wanted.

i have a moog catalog, picked it up when i worked for Car Quest. gimme some more info about the car and what exactly you are looking for. is the car a small block? big block?, you looking to build a stocker? a drag car? or a pro-touring type car?

Brandon,

If you don't mind, I'd like to take you up on your offer regarding Moog Spring Part Numbers from your catalog.

I'm about to replace mine and trying to find the Moog replacements for the front on my El Camino.

I have a 1972 El Camino SS, 350ci, 350Auto, AC, PS, PB. I trying to confirm part numbers that I got from the Aldrich Chart located elsewhere on this web site.

I got from the chart Moog Part # 6330 and or # 5732 that somewhat matches my GM part # 3952813.

Is there any others in the catalog that match these ?? I'd like to keep stock height or perhaps slightly lower (1" or so) with perhaps a heavy duty part number.

Appreciate you taking the time to look.

Thanks,
David

these are all the springs listed for 1972 chevelle/elcamino. most of these springs were also used in 69 so these springs should apply to jbalchs' question too.

6332 .625 12.50 1291 271 17.28 sb 6cyl

to be honest its hard to say which one of these springs will lower the car and how much.

the 5390, 5398 and 5536 all look like good candidates. out of these 3 i like the 5398. it has a larger diameter wire and a higher spring rate which should make the spring stiffer, but the spring is also 1.5 inch shorter in free height.

according to my book the 6330 should be a stock replacement.

Thanks for the help Brandon.

I'm building the car for street/strip, here's some info.........
69SS,454,TH400,4.10,ATI 10",325/50 drag radials

I've got moog springs in the rear (don't remember the #) I think the spring rate was about 40# more and the free height was about 3/4" taller than stock. I'm more interested in good weight transfer than cornering.

the 5390 or 6330 would have come in 69 big block cars,the 5390 is heavy duty.

the 6332 looks like it would work real well, it has the same wire diameter as the 6330 and almost the same free height, but you will notice the load rating is less on the 6332. so it has the same number of coils and wire diameter and will compress more with the cars weight on the springs. in my understanding this all leads to increased stored energy for improved weight transfer.

the 6332 was used on both sb and 6 cylinder, and if im not mistaken this same spring is used by Tom aka MC71454 and his 10 second Monte Carlo. Tom uses This spring along with his upper shock nut trick to help with weight transfer, a low dollar front suspension setup that works very well.

ill warn you though this spring may lower the front end a small amount, but i dont beleive it will be enough to worry about.

hope this helps out guys!!

it seems as if racer1320 uses the 5392 front spring which may be an even better choice, but unfortunately one of the guys in the post i linked to mentioned moog may have quit making it.

specs on 5392
catagories are same as above.
5392 .610 11.50 1719 266 17.95

this spring has a smaller wire diameter and the free height is taller which equals more coils to the spring. this should equate to more stored energy than the 6332. even though the spring has a taller free height than the stock springs the load rating is a few hundred pounds less, which should make the front end the same height as before or a hair lower.

Brandon,

Just wanted to thank you for taking the time to write all those spring spec's. I found it very helpful to make a decision which I will make after I study it more.

Again, thanks,

David

No problem David, glad i could help.

Brandon, thanks for the all the help. You gotta wonder why they discontinued the 5392 spring?

What's the deal with MC71454's front shock 'nut' trick? I searched around for it, but couldn't find anything.

- Jeff

Brandon,

If it's not too much trouble, could you post the spring specs from your catalog for a '67?

I'm trying to choose a new front set now and I think there is a height difference between the early models and the 68-72's.

Rod:

A lot of people have used 6310s on their 67s. I just put in a set of 638s last week that seem to work real well. They are both about 325 rate, 1,750 wt., with free height of about 16 1/4. I don't have exact specs handy but I can try to dig them up. Was not to bad installing - did not need spring compressor. Be careful though. Let me know if you need more help.

These are "lowering springs" by Moog


I have the hard copy catalog at home so I know these are Moog springs. (It doesn't say so in the online catalog.)

Good Luck.

I guess I'm kind of going against the grain here but I really don't care to lower the stance of my car.

I actually just installed new rear springs (5381) which brought up the rear about 2" (no more rubbing w/ 255's, 275's should clear). What I want is decent tire clearance over 235/15's, level or slightly lower than the rear.

I have a big block and aftermarket air (VA so it's lighter than stock), glass inner fenders and possibly a glass bolt on hood in the future.

okay guys here goes


Jeff
the upper shock nut trick is pretty simple. you will need two extra nuts for the upper shock stud (fine thread). you will want to remove the upper shock nuts, remove the rubber bushing and the washer. then reinstall the washer without the rubber bushing. then take the shock nuts and put them back on the shock stud, only screw them on a little bit, once you have done that use the extra nuts on top as jam nuts to keep them in place.

what this does is allow the front end to rise really quick, basically for the first couple of inches there is no shock action, and basically mimics the 90/10 drag shocks. you can also tailor this by the amount you back the nut off of the stud.

Tom uses standard KYB gas shocks up front, he drives to the track with the shocks set up like they are supposed to be. when he gets to the track is when he does this, he races and when hes done he puts it back together again the way its supposed to be. the way i understand it this allows the best of both worlds, a nice gas shock ride to and from the track, but at the track it performs just as well drag shocks.

although i havent tried this at the track as of yet, i have tried it on my 66 out on the street. i can say that it will increase weight transfer and the speed at which the front end rises. i was really impressed with it and there is a noticable difference.

try it, it works! and best of all it doesnt cost anything. well that is if you have the fine thread nuts.

there really isnt very many springs listed in my catalog for 1966/1967 compared to 1968 and up.

Rod i included that 6204 spring because all of the 1967 springs listed were used in 1966 also. the 6204 is the only spring i see listed for 1966 that wasnt used in 1967.

Brandon - got it, that makes sense. basically you've got no shock for upward travel for a split second, until the gap is closed where the bushing once resided. thanks

- Jeff

This site has a lot of spring/setup info. It is very good.

Thanks Brandon, I think I have enough to make my decision now.

no problem, good luck to you guys. and happy holidays!
