Why Choose the ATI918985-76 Elastomer Kit?
The ATI918985-76 Elastomer Kit provides balanced damping characteristics for engines requiring a smooth yet stable response. The softer 60-durometer middle ring absorbs mid-frequency vibrations, while the 70-durometer inner and outer rings deliver the rigidity needed for stability under load. This configuration enhances engine smoothness, reduces wear, and maintains damper efficiencymaking it the perfect choice for performance-oriented builds that need reliable harmonic control without excessive stiffness.
Frequently Asked Questions
What does 70/60/70 durometer mean?
It means the inner and outer elastomer rings are 70-durometer for stability, while the center ring is 60-durometer for additional flexibility and smoother harmonic absorption.
Is this kit compatible with aluminum dampers?
No. The ATI918985-76 kit is designed specifically for steel 5-inch, 3-ring Super Dampers. Aluminum dampers require a different elastomer kit.
What types of engines benefit from this setup?
The 70/60/70 durometer combination is ideal for street performance, endurance racing, or light competition builds that operate across broad RPM ranges.
Should all elastomer rings be replaced together?
Yes. ATI recommends replacing all three rings at once to ensure balanced damping and optimal harmonic control.
