Eagle Chevy LS3 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 4.070in Pistons Rotating Assembly

If you're building a high-performance naturally-aspirated LS3 engine for racing, this Eagle Pro Street rotating assembly is a solid foundation. It brings together all the key rotating components you need to get your build underway, ensuring they're balanced and ready to handle the demands of the track.

This assembly starts with a 4.000-inch forged 4140 crankshaft, chosen for its strength and durability in performance applications. It's paired with 6.125-inch I-beam connecting rods made from robust 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable clamping force. The pistons are forged 4032 DSS units with an inverted dome design, measuring 4.070 inches in bore size, and come with plasma-moly file-fit rings for a good seal. King XP rod and main bearings are included to ensure smooth rotation and proper oil clearance right out of the box.

This rotating assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS applications. It's designed for naturally-aspirated racing use, meaning it's built to withstand the higher RPMs and stresses associated with that type of performance driving. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure all other components in your build are compatible and meet local emissions requirements.
