ATI Damper - 6.78in - Alum - 6/4 Grv - Nissan SR20 - Front Wheel Drive - Street - 2 Ring

This is the ATI 918607 aluminum crankshaft damper, specifically made for Nissan SR20 engines in front-wheel-drive applications. It's designed for street use and features a 2-ring, 6/4 groove setup. A well-built damper like this is crucial for reducing torsional vibrations from the crankshaft, which can help protect your engine from damage over time and ensure smoother operation.

Crafted from aluminum, this damper is lighter than a stock cast-iron unit, which can offer a slight advantage in reducing rotational mass. The 6/4 groove configuration means it has six grooves for the accessory belt on the outer diameter and four grooves on the inner diameter, providing flexibility for accessory drive setups. This damper is a solid option for SR20 owners looking to upgrade their engine's reliability and performance on the street.
