HEY GUYS, I ORDERED NEW SPRINGS FROM MOOG FOR MY 70 STRATO CHIEF AND WAS WONDERING IF ANYONE COULD CONFIRM THE PART#'S I GOT, THE REAR SPRINGS IN THE CAR LOOK TO BE TAPERED oops sorry to yell, and the new ones i got are not, the pn#'s i got are moog, cc601 and moog 6304, if anyone has an idea it would be great before i pull all the suspension out to find out im a moron and ordered the wrong parts...small block car by the way...thanks a bunch dave
1967 - 1969 Chevrolet Biscayne Coil Springs Moog MOOG COIL SPRINGS, SOLD AS PAIR -- Variable Rate Springs, Made From Heat-Treated Alloy Steel For A Full Coil Rebound And Sagging Resistance, Change Resistance When Compressing, Become Progressively ...
THIS IS INFO ON CC601 cargo coils looks like numbers are correct

well it looks like the # is for rear cargo coils which is fine, i will likely screw em all up anyways when i cut a coil out of each but i bet it won't sag or bounce anymore...!

From what I know about Cargo Coils I don't think cutting them will work well.

From what I know, the design of Cargo Coils is such that they need the spring intact to function correctly. I think a normal spring has the same rate regardless of whether it's cut in half or not.
I am by no means an expert on springs and someone more informed may well correct me.

I think Carl is correct cargo coils react according to the weight on them (as in different loads in a wagon) Is this car one of those"tuner cars" lowered down??
WHAT is a Varible (Progressive) Rate Cargo Coil? Varible rate springs deflect at different amounts per inch. An example would be: 200 lbs. = 1 inch deflection, 600 lbs. = 2 inch deflection, 1000 lbs. = 3 inch deflection, and so on. Varible coils have a soft initial spring rate and a much firmer spring rate to handle more weight, decrease sway, and improve handling.
I think with a progressive (cargo) spring for the 70' B rear, you'll be limited to cutting from the top or tightly wound load end. And that should be just fine, as it has a completly circular index. The bottom or control arm end of a cargo coil on these cars, is widely wound and terminates with a progressively tighter pigtail. This tail gets indexed around a raised stamped portion of the spring clamp. It cannot be cut here.
I'd think one coil out of the tightly wound end should not drastically affect the rate, capacity or overall feel.

Thanks very much, that was the plan was to cut ONE coil out of the tightly wound area and no, it most certainly isn't a "slammed tuner car" I just am not a big fan of the stance and would like the whole car to sit down a inch/ inch and a half. Thanks again for looking that up, it confirms what i thought and stops me from worrying about the simple things....
I wouldn't be surprised that with taking one coil out of a new cargo spring, the car may still sit higher than with the old sagging fixed rate springs. Good luck, and let us know how it goes, take some measurements to make a comparison if you can.
Here's a shot of the cargo coils I got out of my parts car, they looked so new I just went with em'. I have absolutely no idea how my 69' rag will eventually sit when the time comes! We'll see.
