About this part

Product Details

This is the Eagle Pro Street rotating assembly, built for Chevy LS2 engines. It's a well-built package designed for naturally-aspirated racing applications, giving you a solid foundation for a performance build. If you're looking to get serious power out of your LS2 without forced induction, this assembly is a popular choice.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, providing the strength needed for demanding use. It features a 58-tooth reluctor wheel, essential for proper engine management on LS2 applications. Connecting the crank to the pistons are 6.125-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable performance under stress. The pistons are forged 4032 Mahle units with an inverted dome design, sized at 4.030 inches, and come with plasma-moly file-fit rings. To top it off, King XP rod and main bearings are included, offering excellent durability and performance.

This assembly is a comprehensive package for rebuilding or upgrading your LS2 engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
