About this part

Product Details

If you're building a high-performance Chevy LS3 engine, this Eagle Competition Rotating Assembly is a solid choice. It's designed to handle the demands of racing, including setups with nitrous or forced induction. This assembly includes a forged 4340 steel crankshaft with a 4.000-inch stroke and a 58-tooth reluctor wheel, which is crucial for proper engine management on many LS applications. The 6.125-inch H-beam connecting rods are made from strong 4340 steel and come with 7/16-inch ARP 8740 bolts for a secure connection.

The pistons are forged 4032 aluminum from Mahle, featuring a -4cc flat top design with a 4.005-inch bore, perfect for achieving a desired compression ratio with the 4.000-inch stroke. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's specific needs and operating conditions. To ensure smooth operation and durability, the assembly includes King XP series rod and main bearings. This complete package is engineered for serious performance builds and fits a range of vehicles including the Cadillac CTS, Chevrolet Camaro, and Chevrolet Corvette.

When assembling a performance engine, using a balanced rotating assembly like this one from Eagle can save you time and ensure proper operation. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
