Frequently Asked Questions
What does 70/70/70 durometer mean?
All three elastomer rings have a 70-durometer hardness, providing even and balanced damping characteristics throughout the RPM range.
Is this compatible with aluminum dampers?
No. The ATI918985-70 kit is designed for steel 5-inch, 3-ring Super Dampers. Aluminum versions require a separate elastomer kit.
Can this be used for high-RPM or performance engines?
Yes. The 70-durometer compound performs well in both street and moderate performance builds needing consistent damping.
Should all three elastomers be replaced at the same time?
Yes. Replacing all rings ensures uniform harmonic balance and optimal vibration control for long-term reliability.
