Eagle Chevy LS3/LS4 3.905in Bore +26.00cc Dish .125in OS Rotating Assembly Kit w/ 24 Tooth Reluctor

This Eagle Competition Rotating Assembly kit gives you the core components to rebuild or upgrade your Chevy LS3 or LS4 engine. Inside this kit, you'll find a 4.000-inch forged 4340 crankshaft, a 24-tooth reluctor, 6.125-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, Mahle forged 4032 pistons with a -26cc inverted dome dish for a 3.905-inch bore, plasma-moly file-fit rings, and King XP rod and main bearings. This assembly is built for demanding use, including racing applications with nitrous or forced induction.

The forged 4340 steel crank and H-beam rods are well-built to handle the stresses of high-performance engines, making them a solid choice for builds pushing beyond stock power levels. The Mahle pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, contributing to improved engine quietness and efficiency. The included King XP bearings are designed for high-load applications, ensuring reliable lubrication and durability for the crankshaft journals. This kit is designed to fit a range of GM vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO, providing a robust foundation for your engine project.

When assembling this rotating group, pay close attention to the file-fit nature of the plasma-moly rings; proper gapping is crucial for sealing and performance. Ensure all components are clean and properly lubricated during installation. This kit is intended for competition use and is not CARB approved, meaning it cannot be shipped to California.
