Why Choose the ATI918990-76 Elastomer Kit?
The ATI918990-76 Elastomer Kit is engineered to maintain perfect harmonic balance while improving drivability and performance. The softer 60-durometer center ring absorbs mid-range vibrations effectively, while the 70-durometer outer sections maintain rigidity at higher RPMs. This configuration ensures precise damping for engines that operate across broad RPM ranges ideal for performance street cars or endurance racers seeking durability and refinement.
Frequently Asked Questions
What does 70/60/70 durometer mean?
The inner and outer elastomer rings are 70-durometer for strength and stability, while the center ring is 60-durometer to allow smoother harmonic absorption and reduced vibration.
Is this compatible with aluminum dampers?
No. The ATI918990-76 is made specifically for steel 6-inch, 2-ring Super Dampers. For aluminum dampers, use the aluminum-specific elastomer version.
Can this setup handle high-RPM performance engines?
Yes. The 70/60/70 configuration performs exceptionally well in street/strip and endurance builds that demand both control and flexibility.
Should both elastomer rings be replaced together?
Yes. Replacing both rings ensures balanced harmonic control and consistent damper performance over time.
