Jul 21st, 2025 | | | | Joined: Sep 2004 Posts: 45 New Guy | | New Guy Joined: Sep 2004 Posts: 45 | I've been installing my new "Champion" radiator this week plus some other little piddely jobs under my '49 . While hooking up the tranny cooler lines I noticed why the cab has been leaning towards the passinger side - the coil spring on the Mustange II suspention is broken and judging by the rust on the joint it has been that way for a while ! I can't believe I never seen this until now . I've been wracking my brain trying to figure out why there was at least 1" sag on that side . I have the Eaton Spring website saved on my computer , anyone have any suggestions on which Rates work best for ride quality? | | | | | Joined: Apr 2006 Posts: 136 Shop Shark | | Shop Shark Joined: Apr 2006 Posts: 136 | More chineese steel huh?

We can't get away from it! Probably not chinese. Ford are well known for failures of their US made coil springs. Probably the best bet would be to contact either Eaton or the manufactuer the suspension came from with the specifics of your truck, like what engine you're running, transmision, etc.

They had springs listed although I didn't check them out. ( I'm sure they are Chinese knowing NAPA ), but if your not putting a lot of miles on the truck, might suffice. | | | | | Joined: Jul 2007 Posts: 328 'Bolter | | 'Bolter Joined: Jul 2007 Posts: 328 | I just installed some Eatons at the rear of my 58 Buick Roadmaster.
Good guys and knowledgeable.
Since you need Mustang spec springs as applied to a full sized truck I'd ask their advice.
I suspect you'd need V8 rated springs w/air conditioning in order to properly suspend the heavier truck weight involved.

Since you are going to buy springs for your truck you might as well get the right ones for your application.
What you want to do is weigh just the front wheels, just the back wheels, and maybe the side wheels to get a split of the weight of your truck. Once you have this the engineers at the Eaton spring tech line will thank you for having this information ready for them, they should be able to get you the right spring for your application.
It is possible it's just another bad spring or it could've been overloaded also.
If you don't have a scale like that round find a race car shop a lot of times they will have scales to tell you your weight of your truck.
Some people say I suffer from insanity, in reality, I enjoy every minute of it!
