ATI Shell Assy - 7.48 - Alum LW - 6 Grv - 3 5/16 CS / 3 3/8 Thru

ATI is well-known for making high-performance harmonic dampers that help engines run smoother and last longer. This particular shell assembly, part number 917092, is a great example of their work, designed to keep your engine's crankshaft running true. It's built from lightweight aluminum, which helps reduce rotational mass in your engine, and features a 7.48-inch diameter. The 6-groove pulley design is important for ensuring your accessory belts stay properly aligned and driven, contributing to consistent operation of your engine's systems.

This damper is designed with a 3 5/16-inch crank snout (CS) and a 3 3/8-inch thru-hole, which are specific measurements to ensure it bolts up correctly to compatible crankshafts. The aluminum construction not only saves weight but also helps dissipate heat effectively. Choosing a well-built damper like this one from ATI can make a notable difference in how smoothly your engine performs, especially under load, and helps protect your crankshaft from damaging vibrations.
