Rear Cargo Coil spring part number ???
I have decided to put cargo coil (variable rate) rear springs in my convertible to help when we have a car full of people going for a cruise.
I know the Moog stock replacement spring is # 6321.
Does anyone know the "cargo coil" or another variable rate spring for the rear of a 67 442 convertible. I am good with it if it raises it a little in the rear. I was never fond of the lower rear the 67 442 had over a Cutlass.
Thanks in advance
Larry

oldcutlass recommended Moog CC507 in this thread:

I have done some calculations myself and thought about ordering Moog 5415 (constant rate) for my 67 Turnpike Cruiser that where recommended by droldsmoreland in this thread (scroll almost to bottom):
https://classicoldsmobile.com/forums...l-springs.html
The official Moog load capacity for the 5415 is even higher than quoted: 950 lbs.
Hope this helps.

"The rear spring set that raise the rear of the car 1.5" and be stiffer and handle well is a MOOG# 5415. This set is about 11% stiffer that the stock HD springs when the car was new. I did install these about 2yrs ago on a friend's 1967 Cutlass Supreme convertible and the results were great. The other benefit is that he added 15" wheels and the extra clearance was about right. The engeneering specs are:
- Wire Diameter .61"
- Installed Ht. 9.0"
- Free Ht. 14.62"
- Load Rate 169# (stk HD for A-body was 140# )
- Load Capacity 849# each spring.
Hope this helps.

I put in the new rear springs. They did not change the ride height much at all. I mean like less than an inch. I also added air lift bags and I am very happy with the ride improvement.
