Spring rates: AAR vs. Hemi leaf springs

[Topcat]

I have brand new AAR, T/A reproduction rear leaf springs, brand new.
I bought em before when I was thinking I would stay with a small block.

Now that I'm going Big block, will the back end sit really high vs. Hemi leafs?
Should I sell these and get a different set that is for a Dana that I plan to buy later?

What are the spring rate differences and traction like in comparison of each other?

the AAR spring s will sit higher & should be slightly softer spring rate , but you have them so why not install them with the 1" lower fornt mount & see fi you like the ride & stance if not it is easy to swap the leafs later

Ditto what CP said.

Stock rate on either set is going to be around 130#. The hemi springs just have an extra half leaf to stiffen up the front segment is all. You could alway s add a pinion snubber too if you have some traction issues.

  Actually, If you where smart.  You could always take the springs to a company that builds springs and have them reset yours and add the extra half leaf, you would be surprised how cheap of an excercise this would be.

Would you know who carries them?


I had a feeling they were pretty close to each other on the rate but knew there had to be some kind of difference.

Thank everyone for your input.
