Product Details
Eagle is well-known for building robust engine components, and this rotating assembly is a prime example of their commitment to performance. If you're building a high-horsepower Chevy LS1 engine, especially for racing applications, this assembly is designed to handle the stress. It includes everything you need to get your bottom end squared away, featuring a forged crankshaft, connecting rods, pistons, rings, and bearings.
At the heart of this assembly is a 3.622-inch forged 4340 crankshaft, chosen for its strength and durability under extreme loads. Paired with this are 6.125-inch H-beam connecting rods, known for their solid construction and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in demanding builds. The pistons are forged 4032 Mahle flat tops with a -4cc dish, measuring 3.898 inches in diameter, and come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, providing excellent wear resistance and smooth operation for the crankshaft.
This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS1 applications. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. If you're aiming for serious power gains and need a foundation that can handle nitrous or forced induction, this Eagle rotating assembly offers a well-built solution.
