“You show two mono springs for the 1968 Camaro Convertible ML001 & ML002, one with cocktail shakers one without. What is the difference?” – Joe
Thank you for your inquiry and a great question.
The frames of the convertibles are not as stiff as those of the coupes and they tend to twist.
The GM engineers figured out if additional weight was hung near the rear bumper the twisting was all but eliminated.
Somehow, and don’t ask me why, these weights became to known as “cocktail shakers”.
Many times the cocktail shakers, for some reason, are not re-installed when restoring convertibles and with 150 lbs missing from the rear of the car and with the stock springs, our ML002, the rear end will sit about 2-inches higher than stock.
To get the back end down where it should be we advise using the coupe ML001 springs.
The 2 springs, ML001 and ML002, have the same spring rate, 126 lbs., but the ML001 has a free arch which is 2-inches lower than the ML002.
I hope this helps you. Now, who else do you know who we can help?
