Frequently Asked Questions
What does 80/70/70 durometer mean?
The inner ring has a harder 80-durometer rating for high-RPM control, while the outer rings are 70-durometer for smoother damping and balance across the RPM range.
Is this compatible with aluminum dampers?
No. The ATI918970-87 is specifically designed for steel 7-inch 2-ring Super Dampers. Aluminum versions require a different elastomer kit.
Can this be used for race engines?
Yes. The 80/70/70 configuration is engineered for high-RPM, forced-induction, and competition applications.
Should I replace both elastomer rings at the same time?
Yes. Replacing both rings ensures balanced damping and consistent harmonic control throughout the dampers lifespan.
