The 58-tooth reluctor wheel ensures proper crank position sensing for these modern GM V8s. This assembly is built for serious performance, whether you're pushing the limits with nitrous or forced induction, making it a solid choice for racing applications.
The heart of this assembly includes 6.125-inch long H-beam connecting rods. These rods are well-known for their strength and ability to handle significant cylinder pressures, which is crucial when you're aiming for maximum horsepower. Paired with these rods are 4.040-inch diameter pistons, sized to match the bore of many popular LS engine builds. The combination of these components creates a robust rotating assembly ready to endure the demands of high-performance engines.
When building a powerful LS engine, the rotating assembly is where a lot of the magic happens. Eagle has a reputation for producing well-built components that can handle the stress of competition. This kit includes the crankshaft, connecting rods, and pistons, giving you the core pieces for your engine's bottom end.
