This is the PRW 2344041 Sportsman series harmonic balancer, built for high-performance Big Block Mopar V8 engines. If you're building or rebuilding a powerful Mopar motor, this part helps dampen harmful crankshaft vibrations that can cause wear and tear at high RPMs.

It's a brand new, high-quality component designed as an upgrade or replacement for stock units. PRW is known for its performance valvetrain and engine parts, and this balancer comes with a 1-year manufacturer's warranty. It's sold as the balancer unit itself; installation hardware typically isn't included, so you may need a proper bolt and washer.

Before buying, it's crucial to confirm this is the correct part for your specific engine setup (e.g., 440, etc.). For exact fitment and technical questions, PRW recommends contacting their tech line at 440-502-7256 with your engine details. This is a serious piece for muscle car, race, or street performance builds where reducing vibration and ensuring engine longevity are key.
