Moog CC501

[Ed Valvo]

Anyone running this spring in the rear? If I understand the book correctly, it should be lower and stiffer than the CC651 and CC627.

The stock spring 5379 is rated at 8.5" at 760lbs, with a 121 lb/in rate.
CC627 is also 8.5" at 760 lbs, 122 lb/in.
5413 is 8.4" at 760, 167 lb/in.
CC501 is 8.3" @ 760 lbs, 175 lb/in.

So yes, CC501 should be about 1/4" lower and stiffer than stock.

6377 is 8.3" at 760 lbs, 141 lb/in.
5409 is 8.1" at 760 lbs, or about 1/2" lower than stock, 143 lb/in.

CC651 is 7.9" at 760 lbs, 116 lb/in

6319 is 7.8" at 760 lbs, or about 3/4" lower than stock, 119 lb/in
5401 will be 7.2" at 760 lbs, or about 1 and 1/4 inch lower than stock, 129 lb/in
