ATI Damper - 6.78in - Alum - 4 & 6 Grv - Honda H22 - Street - 4 Percent & 9 Percent OD Sizes

This is an ATI 6.78-inch aluminum crankshaft damper specifically made for Honda H22 engines. It's designed for street applications and includes options for both 4 and 6 groove pulleys, along with 4 percent and 9 percent overdrive sizes. A crankshaft damper, also known as a harmonic balancer, is crucial for absorbing torsional vibrations that occur in the crankshaft during engine operation. These vibrations can cause stress and damage to the crankshaft over time, especially in performance applications.

ATI is well-known for building robust performance engine components, and this damper is no exception. It's constructed from aluminum for a lighter weight compared to steel alternatives, which can be beneficial for overall engine balance and responsiveness. The inclusion of multiple groove options for the pulley system allows for flexibility in accessory drive setups, while the selectable overdrive sizes can help slightly increase the speed of accessories like the alternator or water pump, which can be useful for cooling or electrical demands in a tuned engine. This damper is a solid option for H22 owners looking to protect their engine and potentially gain a slight performance advantage.
