What is the purpose of the elastomer rings in an ATI Super Damper?

The elastomer rings are designed to absorb torsional vibrations that travel through the crankshaft. This helps protect the crankshaft and other engine components from damage caused by these vibrations.

How do I know if I need to replace my elastomer rings?

Signs include increased engine vibration, especially at certain RPMs, or if the existing rings appear cracked, hardened, or degraded. It's also good practice to replace them during a damper rebuild.

Does this kit include everything needed to replace the rings?

This kit includes the 3 specific elastomer rings (70/60/70 durometer). You will need to disassemble your ATI Super Damper to install them, and it's recommended to consult the damper's service instructions.

About this part

Product Details

This is the ATI 3-ring elastomer kit, part number 918985-76. It's designed to replace the rubber dampening rings inside an ATI Super Damper crankshaft pulley. These dampers are crucial for reducing torsional vibrations that travel down the crankshaft from combustion events. Over time, the rubber in these rings can degrade, leading to reduced vibration control and potential damage to other engine components. This kit includes the specific 70/60/70 durometer rings needed for certain ATI damper models.

Replacing these elastomer rings is a key part of maintaining the effectiveness of your ATI Super Damper. The different durometer ratings (hardness) of the rings are carefully chosen by ATI to absorb specific frequencies of vibration. Using the correct replacement kit ensures your damper continues to protect your engine's crankshaft from harmful harmonics. This is a well-built component that helps keep your engine running smoothly and prevents premature wear.
