Frequently Asked Questions
What does 80/70/70 durometer mean?
The inner elastomer ring is 80-durometer for added stiffness, while the two outer rings are 70-durometer for balanced harmonic damping and flexibility.
Is this compatible with aluminum dampers?
No. The ATI918980-87 kit is designed specifically for steel 6-inch, 3-ring Super Dampers. Aluminum dampers require a dedicated elastomer version.
Can this kit handle forced induction or high compression?
Yes. The 80/70/70 durometer configuration is ideal for supercharged, turbocharged, or nitrous-assisted engines operating at high RPM.
Should all elastomer rings be replaced together?
Yes. Replacing all three elastomers at once ensures balanced damping, maximum reliability, and optimal damper performance.
