What is a crankshaft damper and why is it important?

A crankshaft damper, also known as a harmonic balancer, helps to reduce torsional vibrations from the crankshaft. These vibrations can cause stress and damage to the engine over time. This damper helps to smooth out those vibrations for a more stable engine operation.

What does the 3-ring and 4-groove pulley design mean?

The 3-ring design allows for the mounting of multiple pulleys on the damper. Each of the two included pulleys has 4 grooves, meaning you can drive up to two separate accessories or belts from the crankshaft using this setup.

What is the benefit of an aluminum crankshaft damper?

Aluminum construction makes this damper lighter than a traditional steel one. Reducing rotational mass in the engine can contribute to improved engine response and potentially slightly better acceleration.

About this part

Product Details

ATI is well-known for making strong, reliable performance parts, and this crankshaft damper is no exception. This specific damper is designed for the Mitsubishi Eclipse with the 4G63 engine. It's a 6.78-inch aluminum unit featuring a 3-ring design with two 4-groove pulleys, making it a solid choice for builds where you need to drive multiple accessories or pulleys.

Crafted from aluminum, this damper is lighter than a steel equivalent, which can help reduce rotational mass in the engine. The 3-ring design is a key feature, allowing for the attachment of multiple pulleys for accessories like power steering pumps, alternators, or air conditioning compressors, all driven by the crankshaft. This makes it a versatile component for custom engine setups or performance builds where accessory drive needs are specific.
