About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to build a strong LS3 engine for naturally-aspirated racing applications. You get a 4.000-inch forged 4140 crankshaft, a 24-tooth reluctor wheel, 6.125-inch 4340 I-beam connecting rods with 7/16-inch ARP 8740 bolts, forged 4032 DSS pistons with an inverted dome design for a -15cc volume, plasma-moly file-fit piston rings, and King XP rod and main bearings. This is a well-built package designed to handle the demands of the track.

The forged 4140 steel crankshaft is built for durability, and the 4340 I-beam connecting rods are a solid choice for racing, especially when paired with ARP 8740 bolts for secure clamping force. The 4032 forged aluminum pistons are a good match for performance builds, offering a balance of strength and lighter weight compared to cast pistons. They come with plasma-moly file-fit rings, which means you'll need to gap them to your specific application for optimal performance and sealing. King XP bearings are included to ensure smooth rotation and proper oil clearance for both the main and rod journals.

This assembly is intended for naturally-aspirated racing use. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
