ATI Damper - 5.50in - Alum - 4 & 5 Grv - Subaru WRX EJ20 22 25 Engine 1Pc

This ATI crankshaft damper is a well-built component designed for Subaru WRX models with EJ20, EJ22, and EJ25 engines. You get the 5.50-inch aluminum damper itself, ready to help manage the torsional vibrations that occur within your engine's crankshaft. This is crucial for protecting your engine's internal components from excessive stress and wear over time.

Crafted from aluminum, this damper is lighter than a stock cast-iron unit, which can offer a slight advantage in reducing rotational mass. It's configured to work with either 4 or 5-groove serpentine belt setups, offering flexibility for different accessory drive configurations. By absorbing these harmful vibrations, the ATI damper helps ensure smoother engine operation and contributes to the overall durability of your EJ-series engine, especially important for performance-oriented applications.
