Topic: GT 350 Spring ID Colors

[Bossbill]

I'm fairly certain I didn't mix up my GT350 springs with others I have laying around.
But, to make sure...

I'm showing light purple (lavender) and yellow.

Correct?

My 67 GTA, 289, also is lavender/yellow.  I would suspect that a GT 350 would have a higher spring rate.  I would also suspect that documentation of Shelby springs is exponentially better than what I have due to the value of the vehicle, so expect additional responses with definitive information.

These match some other GT350 4 speed non AC examples I have within about 70 (sequential VIN's) from your car. So IMHO yes your good to go with those for your application

Thanks, Jeff! I'll measure the stripes and post their width and offset to each other later. I recall a post about the width in another spring thread.

[conjecture]
In racing there is the big spring/small swaybar approach and the small spring/big swaybar approach.
The competition suspension could be the later with a stockish spring, but a much bigger swaybar.
And much better shocks.

[edit]
Width of paint mark is about 1/2" for each color.
Distance from each is about 7/8".
The spring rested on the flat end when the marks were applied (brush?) as they sag toward that end.

+1 Exactly what we typically see. Yes the ID stripes were typically applied with brush during these years
