What is the purpose of the elastomer in a crankshaft damper?

The elastomer inside a crankshaft damper is designed to absorb torsional vibrations and harmonics that travel through the crankshaft. This helps protect the engine from damaging vibrations and ensures smoother operation.

What does the '70/70/70' refer to in this kit?

The '70/70/70' refers to the durometer rating of the three elastomer rings included in the kit. Durometer measures the hardness of rubber and rubber-like materials, indicating the stiffness and dampening capability of the elastomer.

How often should crankshaft damper elastomers be replaced?

Crankshaft damper elastomers typically need replacement when they show signs of wear, such as cracking, separation, or increased engine vibration. Regular inspection during other engine maintenance can help identify when replacement is necessary.

About this part

Product Details

This ATI 3-ring elastomer kit, specifically the 7-ring version with 70/70/70 durometer, is designed to replace the internal dampening elements within an ATI Super Damper crankshaft pulley. The elastomer is crucial for absorbing torsional vibrations that travel down the crankshaft, helping to protect the engine from harmful harmonics. When these elastomers wear out, they can lead to increased vibration and potential damage over time.

ATI uses a specific durometer rating, like the 70 on this kit, to control the stiffness and dampening characteristics. This particular kit is intended for applications where a specific level of vibration control is needed, balancing performance with engine protection. Replacing these worn-out components with a fresh ATI kit helps restore the damper's ability to manage engine vibrations effectively, contributing to a smoother running engine and potentially extending its lifespan.
