Harmonic anti vibration springs

[John H]

Hey, Do I need the anti-vibration springs on my 15" brake drums? I have 1 with an original one and one without anything. I am in the middle of putting my rear end bake together etc. If I do, where would you guys recommend I buy them.
Thanks, John

Well if you determine that you need them, this is my video showing the way to easily install them!

15" drums? I don't think so. Measure inside the drum. They repop them for 11" drums. May be different sizes too. 11" Brake Drum Springs, Brake Drums, 158-BS564S Reproduction, NOS and Used Mopar Muscle Car Parts

ok. I meant I have 15" tires on my car... Sorry.

I am curious on their purpose, I have them on my Imperials.

Brake drum harmonics. Ever seen brake drum and rotors being cut on a brake lathe? If the rubber bands aren't used, they howl something awful!!!

I wonder if All drums should have the springs ?

Couldn't say, but most Mopar drums, but not all, have/had springs. Maybe better drum technology aided in harmonic self-cancellation?? Or maybe it really doesn't matter?
