About this part

Product Details

This is the Eagle Chevy LS3 Competition Rotating Assembly, built for serious performance builds. If you're putting together a powerful LS3 engine for racing, especially with nitrous or forced induction, this assembly is designed to handle the stress. It includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced and ready to be installed into your LS3 block.

At the heart of this assembly is a 3.622-inch forged 4340 steel crankshaft, known for its strength and durability under high loads. It's paired with 6.125-inch H-beam connecting rods, which are also forged from 4340 steel and secured with 7/16-inch ARP 8740 bolts for reliable performance. The pistons are forged 2618 aluminum from Mahle, featuring an inverted dome design with a -12cc volume and a 4.070-inch bore size, perfect for achieving specific compression ratios. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's needs. To top it off, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for the rotating assembly.

This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS3 applications. It's important to note that this assembly is not CARB approved and cannot be shipped to California. For optimal results, professional balancing and installation by a qualified mechanic are recommended to ensure longevity and peak performance from your new engine build.
