Thread: Need info on use of Moog CC655 Springs.

Thanks for the weight info on the Studebaker 6 cylinder engine.
Questions:
1) I'm not proficient navigating this web site. I was on a thread titled "Moog CC655 springs in the February 2011 Co Operator questions" that had some interesting information. That is the thread that I think I posted on on 12/31/15 (see post above), but it shows up on this thread. (?)
2) I cannot find the thread mentioned in #1) - any suggestions?
3) Regarding Moog springs for my '54 Starliner I have the following weight estimation for my aluminum block LS1/T56 vs a Stude V8/automatic transmission:

Stude V8 - 650#
Stude auto w/torque conv - 220#
Total - 870#

Stude 6 - 470#
Stude auto - 220#
Total - 690#

LS1 w/ acc - 450#
T56 w/flywheel, clutch - 185#
Total - 645#

And for reference:
SBC - 550#
700R4 with torque conv - 225#
Total - 775#

Therefore it looks like I am 225# lighter than a Stude V8/auto (870-645=225#)
It looks like I am about 50# lighter than the Stude 6/auto.
Also, for reference, it looks like a SBC/700R4 is only about 95# lighter than the Stude (870-775=95#)

I currently have a Champion spring with one coil cut off (which increased the spring rate, but I do not know by how much), and other than being too low that seems to work. I would prefer a progressive spring, but the Moog CC655 that looks like it is recommended for a Stude V8 and it may be too high of a spring rate (?). Of course the other question is how much a CC655 would lift the car - not an easy one to answer without installing new springs.
I have found new replacement Champion springs for $570?????? (At least that is for a pair.) (That's also the ballpark for new QA1 coil overs (I am using QA1 adjustable shocks))) I can buy a pair of new Moog CC655 from RockAuto.com for less than $60.

OK, here is the question:
What is the spring rate for a '54 Stude Champion coil spring? With that I can research the Moog problem solver https://www.moogproblemsolver.com/moo…rings_Spec.pdf to see if they have a suitable spring.

I am also open to any critique of my logic/estimates, anything will be helpful.

Thanks,

Which one do you have?

I have no idea. This info is stamped on the spring? Unfortunately they are currently installed. Can you give me the spring rates for the list you provided?

Yes, the info is stamped on the last coil that is flattened out, if you have one coil cut, you are missing one ID end. I do not have the specs for all of the ones above. The last 53-4 Champion I have worked on was in 68. If you could tell me the diameter of the spring wire and the number of active coils and the installed height I could get you in the ballpark.

The car is assembled, so I will not be able to get that kind of information until I can get things taken apart. May be Spring time.

"May be Spring time." (sorry, I just couldn't let this pass... in this thread.)

I asked Stude Intern'l and they don't list them, although there is someone doing a search. Forget about asking the counter-bots at NAPA or the like. This was stuff from before the "Beginning of Time" for most of them.

I purchased some form Stude Itnl. last year. I gave them the # from the Avanti Parts Catalog. However, the washers were not NOS but rather a generic without the marks or stampings. Minor detail, but My suspension had never been apart and everything was original. My "helper" misplaced 4.

Yes, thanks.... Here's what I figured out. I ordered 4 from SI and they were almost flat, so rejected them asthought they would not be suitable. Emailed Dave Thibeault and he said could provide NOS. .... Ordered them and they were ALSO FLAT.

The original washers had a geometric curve that allowed the smaller diameter to bite onto the inner bushing sleeve and lock it against the mounting pin, so as to immobilize the bushing on the shaft.

Realizing that the NEW A-Arm bushings were a GM(?) design, NOT actually what Studebaker used, the inner bushing sleeve is longer than the original. The FLAT washers would actually work, but are still too tight (IMO) against the rubber.

What I did was to get a dozen Metric washers (12mm?) and ground the edges down so they'd fit inside the new rubber and around the cap bolt shoulder, which in effect, acts to extend the inner sleeve even further out. After a test on a spare pin, found that 2 washers per bushing work very well (1/8"?).


After tightening, they'll be about 3/16" closer to the bushing...
