Product Details
What you get in this rotating assembly is a complete package designed to get your Chevy LS2 or LS3 engine built for performance. This kit includes a 3.900-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 4.060-inch pistons, all balanced and ready to go. This assembly is specifically put together for naturally-aspirated racing applications, meaning it's built to handle the demands of engines that don't use forced induction like turbos or superchargers.
Eagle has put together this Pro Street Rotating Assembly with durability and performance in mind for racing. The I-beam connecting rods are a strong choice for this kind of build, offering a good balance of strength and weight. The crankshaft is forged, giving it the toughness needed for higher RPMs and the stresses of racing. The pistons are designed to work with this setup, completing the core of your engine's bottom end. This assembly is balanced, which is a critical step that saves you time and ensures smoother operation once installed in your engine.
When you're building an engine for racing, especially a naturally-aspirated setup, the rotating assembly is the heart of it all. This Eagle assembly is a solid option because it brings together key components that are known to work well together. Remember that this assembly is not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications when putting this into your engine block.
