Paired with these are 4.155-inch pistons, completing a well-matched set that's ready to handle the demands of naturally-aspirated racing.
Eagle has put together this Pro Street rotating assembly with naturally-aspirated racing in mind. The combination of the crankshaft stroke, rod length, and piston bore size creates a robust package that's balanced for optimal performance and durability. This assembly is a solid choice when you're rebuilding or upgrading your LS7 engine for track use where consistent power delivery is key. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
When planning your build, consider that this is a significant component.
