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

The elastomer acts as a cushion between the inner and outer parts of the crankshaft damper. Its job is to absorb the torsional vibrations generated by the engine's firing pulses, preventing them from reaching the crankshaft and drivetrain.

How do I know if I need to replace my crankshaft damper elastomer?

Signs include increased engine vibration, especially at idle or under load, or visible cracking or deterioration of the rubber in your existing damper. If your damper is original and the vehicle has high mileage, replacement is often a good preventative measure.

What does '70 durometer' mean for this elastomer kit?

Durometer is a measure of hardness. A 70 durometer rating indicates a medium-hard rubber compound, which is commonly used in crankshaft dampers to balance vibration absorption with durability.

About this part

Product Details

The 70 durometer elastomer in this ATI kit is a key component for your crankshaft damper. This specific hardness is chosen to absorb vibrations effectively, helping to protect your engine's crankshaft from torsional stress. When your damper's original elastomer wears out, it can lead to increased engine vibration and potential damage over time.

This kit includes three rings, each with a 70 durometer rating, designed to fit specific ATI dampers. Replacing the elastomer is a practical way to restore the damping function of your crankshaft pulley, ensuring smoother engine operation and prolonging the life of your crankshaft. It's a solid option for anyone rebuilding or maintaining their engine's front-end components.
