Frequently Asked Questions
What does 80/80/70 durometer mean?
The inner and middle elastomer rings are 80-durometer for maximum stiffness, while the outer ring is 70-durometer for flexible vibration control.
Is this compatible with aluminum dampers?
No. The ATI918970-80 kit is designed specifically for steel 7-inch 2-ring Super Dampers. Use an aluminum-specific version for aluminum dampers.
What types of builds benefit from this setup?
The 80/80/70 configuration is ideal for high-RPM, forced-induction, or high-horsepower racing engines where harmonic control is critical.
Should I replace both elastomer rings together?
Yes. Replacing the full set ensures consistent performance, proper balance, and long-term damper reliability.
