Product Details
This Eagle Competition Rotating Assembly gives you a complete package for building a high-performance Chevy LS1 engine. You get a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and pistons with a -5cc dish volume, all designed to work together. This assembly is specifically configured for LS1 engines featuring a 58-tooth reluctor wheel, which is crucial for proper engine management and timing.
Eagle has put together this assembly with racing in mind, meaning it's built to handle the stresses of competition, including the demands of nitrous oxide injection and forced induction setups. The H-beam connecting rods are well-known for their strength and ability to withstand high horsepower loads, making them a popular choice for performance builds. The crankshaft is forged for durability, and the pistons are designed to complement the stroke and rod length for optimal engine balance and performance. This is a solid foundation for an engine that needs to perform under pressure.
When assembling your engine, ensure you follow the manufacturer's specifications for bearing clearances and piston ring gap, as these are critical for the longevity and performance of a high-stress rotating assembly. This kit is intended for off-road use and is not CARB approved, so it cannot be shipped to California. It also carries a Prop 65 warning.
