Why Choose the ATI918960-90 Elastomer Kit?

The ATI918960-90 Elastomer Kit is designed for extreme power applications where traditional damping materials can’t keep up. The dual 90-durometer inner rings provide exceptional stiffness for precise harmonic control at high RPM, while the 70-durometer outer ring absorbs mid-frequency vibrations to maintain balance and smoothness. This configuration is ideal for engines with superchargers, turbochargers, or high-compression builds that require absolute stability and protection from vibration-induced damage.

Frequently Asked Questions

What does 90/90/70 durometer mean?

The inner and middle rings are 90-durometer for maximum stiffness and control, while the outer ring is 70-durometer for flexible vibration absorption at lower frequencies.

Is this setup too stiff for street use?

Yes, the 90/90/70 configuration is primarily intended for race and competition engines that operate at sustained high RPM or extreme power levels.

Is this compatible with aluminum dampers?

No. The ATI918960-90 kit is made for steel 7-inch Super Dampers. Aluminum dampers require a specific elastomer version.

What type of builds benefit from this kit?

This kit is ideal for forced-induction, nitrous, or high-RPM race builds that demand the highest level of harmonic control and crankshaft protection.
