Frequently Asked Questions
What does 80/70/70 durometer mean?
The 80/70/70 configuration means the inner ring is stiffer (80 durometer) while the outer two are softer (70 durometer), offering a progressive damping effect for high-performance engines.
Is this kit compatible with aluminum dampers?
No. The ATI918959-87 is intended for steel Super Dampers. For aluminum models, use the appropriate aluminum-specific kit.
Do all three elastomers need to be replaced at once?
Yes. Replacing all three ensures balanced damping and consistent performance across the dampers operating range.
Is this a direct-fit replacement?
Yes. Its a direct replacement kit designed for 8-inch, 3-ring ATI Super Dampers without modification.
