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

The elastomer rings are the core of the ATI Super Damper's function. They absorb torsional vibrations from the crankshaft, preventing them from reaching other parts of the engine and reducing stress on the crankshaft itself.

How do I know if I need to replace my damper elastomers?

Signs that your elastomers may need replacing include visible cracking or degradation of the rubber, or if you notice increased engine vibration that wasn't there before. It's also good practice to replace them during a major engine rebuild or if the damper has significant mileage.

Does this kit include the outer housing or just the rubber rings?

This kit specifically contains the replacement elastomer rings only. You will need to reuse the existing outer housing and inertia ring from your ATI Super Damper.

About this part

Product Details

This is the ATI 3-ring elastomer kit, part number 918985-80. It's designed to replace the rubber dampening rings inside your ATI Super Damper crankshaft pulley. Over time, these elastomers can break down from heat and stress, which can affect the damper's ability to absorb torsional vibrations. Replacing them is a key part of maintaining the performance and longevity of your engine's crankshaft.

This particular kit includes three rings with specific durometer ratings: 80, 80, and 70. These ratings refer to the hardness of the elastomer, and using the correct combination is crucial for the damper to function as intended. ATI dampers are well-known for their ability to protect the crankshaft from damaging vibrations, especially in high-performance or modified engines. Keeping the elastomers in good shape ensures your damper is doing its job effectively.
