About this part

Product Details

This Eagle rotating assembly gives you the core components to rebuild or upgrade your Chevy LS 4.8L or 5.3L engine. You get a forged 4.000-inch stroke crankshaft, a set of 6.125-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and a set of 3.820-inch inverted dome pistons designed for a -15cc volume. This assembly is built with a 24-tooth reluctor wheel, making it suitable for many LS applications.

The forged 4340 steel crankshaft is a strong foundation for high-performance builds, and the H-beam connecting rods are well-suited for the stresses of racing, including nitrous and forced induction. The pistons are made from forged 4032 aluminum, which offers good thermal expansion properties, and they come with plasma-moly file-fit rings. This kit also includes King XP rod and main bearings, which are known for their durability in demanding conditions. This is a comprehensive package designed to handle significant power.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. Please consult your engine builder or refer to manufacturer specifications for any additional components or machining required for your specific build.
