About this part

Product Details

Starting with a 4.125-inch forged 4340 crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might involve nitrous or forced induction. The crankshaft features a 24-tooth reluctor wheel, essential for proper engine management on many modern performance builds.

Complementing the robust crankshaft are 6.125-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts. These rods are well-built to handle the stresses of high-RPM operation. The assembly includes forged 2618 aluminum pistons with a -4.6cc flat top dish, measuring 4.135 inches in bore diameter. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. For the bottom end, King XP rod and main bearings are included, known for their durability and performance under load.

This is a comprehensive rotating assembly designed for builders looking to put together a strong LS7 engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It is recommended to consult manufacturer instructions for proper installation and assembly procedures.
