Why Choose the ATI918960-87AL Elastomer Kit?
The ATI918960-87AL Elastomer Kit delivers the ideal combination of stiffness and flexibility for 7-inch aluminum Super Dampers. With stiffer 80-durometer inner and outer rings surrounding a 70-durometer center, this setup ensures superior harmonic absorption at high RPMs without sacrificing smoothness during lower-speed operation. Its the preferred choice for professional racers and high-performance engine builders who demand long-lasting, precise damping under extreme conditions.
Frequently Asked Questions
What does 80/70/80 durometer mean?
The inner and outer rings have 80-durometer hardness for maximum stiffness and control, while the middle ring has a 70-durometer compound for balanced harmonic absorption.
Is this compatible with steel dampers?
No. The ATI918960-87AL is specifically designed for aluminum 7-inch Super Dampers. Use the ATI918960-87 kit for steel models.
Is this setup good for forced-induction or racing applications?
Yes. The 80/70/80 configuration is ideal for supercharged, turbocharged, or high-RPM racing engines that require firm, controlled damping.
Do I need to replace all elastomer rings?
Yes. Replacing all three rings ensures balanced performance, proper harmonic control, and extended damper life.
