Frequently Asked Questions
What does the 80/80/70 durometer configuration mean?
The inner and middle rings use 80-durometer hardness for increased rigidity and control, while the outer 70-durometer ring provides slight flexibility for balanced vibration absorption.
Is this compatible with aluminum dampers?
No. The ATI918960-80 kit is specifically made for steel 7-inch Super Dampers. Use aluminum-specific versions for aluminum dampers.
Is this setup good for high-horsepower engines?
Yes. The 80/80/70 configuration is ideal for forced induction, nitrous, and high-RPM builds where maximum damping strength is needed.
Should I replace all three elastomers?
Yes. Always replace the full set to maintain proper balance and harmonic performance.
