Why Choose the ATI918985-80 Elastomer Kit?
The ATI918985-80 Elastomer Kit is engineered to deliver race-level vibration control for small-diameter Super Dampers. The dual 80-durometer inner rings provide rigidity and stability at high RPMs, while the 70-durometer outer ring adds a layer of vibration absorption for smoother operation. This design ensures precise harmonic control, reduced component wear, and maximum power transfer a must-have for serious performance builds.
Frequently Asked Questions
What does 80/80/70 durometer mean?
The two inner elastomer rings are 80-durometer for stiffness and control, while the outer ring is 70-durometer for smoother harmonic damping.
Is this compatible with aluminum dampers?
No. The ATI918985-80 kit is specifically designed for steel 5-inch, 3-ring Super Dampers. Aluminum dampers require a different elastomer configuration.
Can this kit handle high-RPM racing applications?
Yes. The 80/80/70 setup is built for high-RPM, forced-induction, or high-compression racing engines where maximum stability is essential.
Should I replace all elastomers at once?
Yes. Replacing all three elastomer rings ensures uniform harmonic control and consistent damper performance over time.
