About this part

Product Details

Starting with a 4.000-inch forged 4340 steel crankshaft featuring a long snout and a 58-tooth reluctor wheel, this rotating assembly is built for serious performance applications. This is the heart of your engine's power delivery, and Eagle has put together a well-built package designed to handle the demands of racing, including nitrous and forced induction setups. The crankshaft's robust construction is matched by the included 6.125-inch I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts, ensuring they can withstand high RPMs and significant cylinder pressures.

Complementing the crank and rods are the 4.005-inch Mahle forged 4032 pistons. These are flat-top pistons with a -4cc dish, designed to work with the rest of the assembly for optimal compression. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gaps precisely for your specific build. For smooth operation and durability, the assembly includes King XP rod and main bearings, known for their ability to handle heavy loads and maintain oil film under stress.

This complete rotating assembly is a significant upgrade for anyone looking to build a high-horsepower LS2 engine for racing. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or refer to manufacturer instructions for proper installation and tuning to get the most out of this competition-grade rotating assembly.
