""called eaton Detroit springs, and they say the only difference between a 43 vs a 44 is the bushing in not present on the 44.
But show the same spring construction and arch.""

""They said they definitely are a heavy duty spring.""

Did they give you a spring rate for the 43/44 springs? I have been looking and I can not find the spring rate for my 43's.

Thanks


EDIT:
I emailed Eaton and this is their response for the Chrysler 3400043 spring:
""That would be our ML235 spring. It has a rate of 110 lbs.""
