Why Choose the ATI918960-86 Elastomer Kit?
The ATI918960-86 Elastomer Kit provides superior torsional control through its staggered 80/60/70 durometer configuration. The stiffer inner ring delivers excellent high-RPM stability, while the softer mid-section absorbs mid-frequency vibrations to prevent harmonic resonance. This results in smoother operation, reduced component wear, and consistent damper performance across your entire powerband. Perfect for aggressive street engines, endurance builds, or drag race setups.
Frequently Asked Questions
What does the 80/60/70 durometer configuration do?
It uses a stiffer 80-durometer inner ring for high-RPM control, a softer 60-durometer center for vibration absorption, and a 70-durometer outer ring for balanced harmonic response.
Can this be used with aluminum dampers?
No. The ATI918960-86 is designed for steel 7-inch Super Dampers. Aluminum dampers require an aluminum-specific kit.
Is this ideal for high-horsepower engines?
Yes. The staggered durometer design provides exceptional stability for forced induction, nitrous, or high-compression engines.
Should all elastomers be replaced at once?
Yes. Replacing all three rings ensures proper damping consistency and balance across your damper assembly.
