ATI Shell Assy - 7.95 - Alum - 12 & 6 Grv - Dodge - 5.7L - Nhra Drag Pak - Challenger - 3 Ring

This is the ATI Shell Assy, part number 918484S, specifically designed for Dodge Challenger NHRA Drag Pak models equipped with the 5.7L Hemi engine. It's a 7.95-inch aluminum crankshaft damper that plays a crucial role in managing torsional vibrations from the engine's crankshaft. For high-performance applications like drag racing, controlling these vibrations is key to engine longevity and consistent power delivery.

Crafted from aluminum, this damper is built to withstand the rigors of demanding use. It features a 3-ring design with 12 and 6 grooves, which ATI uses to precisely tune the damping characteristics for specific engine speeds and loads. This updated design helps to reduce stress on the crankshaft and main bearings, especially important in drag racing where engines are subjected to extreme forces and rapid RPM changes. The aluminum construction also helps to keep overall weight down, a consideration in performance vehicles.

When you're building a serious drag car, especially one intended for NHRA competition, attention to detail on critical components like the crankshaft damper is paramount. This ATI unit is a well-built piece intended for those who understand the importance of proper engine balancing and vibration control. It's designed to fit right into your 5.7L Hemi Challenger Drag Pak, providing a solid option for your performance build.
