What is the purpose of the elastomer rings in a harmonic balancer?

The elastomer rings are designed to absorb torsional vibrations from the crankshaft. This helps to smooth out engine operation and protect critical engine components from damaging harmonic forces.

What does the durometer rating (e.g., 80/80/70) mean?

The durometer rating measures the hardness of the rubber. A higher number indicates a stiffer elastomer. Different durometers are used to tune the balancer's effectiveness across a range of engine frequencies.

Do I need any special tools to install this elastomer kit?

Installation typically involves disassembling the harmonic balancer to replace the old rings with the new ones. Refer to the manufacturer's instructions for specific tool requirements and procedures.

About this part

Product Details

This is the ATI 3-ring elastomer kit, part number 918960-80. It's designed to replace the rubber dampening rings within ATI Super Harmonic Balancers. These elastomers are crucial for absorbing torsional vibrations from the crankshaft, which helps protect your engine from damaging harmonics. Over time, the original rubber can degrade, lose its effectiveness, or even crack, making a replacement kit essential for maintaining proper engine balance and longevity.

This specific kit features three rings with durometer ratings of 80, 80, and 70. The durometer rating indicates the hardness of the rubber; higher numbers mean a stiffer elastomer. Different durometers are used to tune the damper's response to specific engine frequencies. Replacing these worn-out rings with a fresh set from ATI ensures your harmonic balancer can do its job effectively, smoothing out engine operation and reducing stress on critical internal components like the crankshaft and connecting rods.
