Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -29cc 3.913in Pistons Rotating Assembly

Starting with a forged 4340 steel crankshaft with a 4.000-inch stroke is key to building a strong LS1 engine. This Eagle rotating assembly uses that robust crank, paired with 6.125-inch H-beam connecting rods featuring 7/16-inch ARP 8740 bolts. These components are built to handle the stresses of racing, including nitrous and forced induction applications, making it a solid foundation for a high-performance LS1 build.

The pistons in this assembly are forged 4032 DSS units with an inverted dome design, offering a -29cc volume and a 3.913-inch bore size. They come with plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing in demanding conditions. To ensure smooth operation and durability, the assembly includes King XP rod and main bearings, known for their performance in high-stress environments. The crankshaft also features a 58-tooth reluctor wheel, essential for proper engine management on LS1 platforms.

This is a comprehensive rotating assembly designed for serious performance builds. It includes the crankshaft, connecting rods, pistons with rings, and main and rod bearings. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
