Eagle Chevy 4.8/5.3 LS 4.000in Crank 58 Tth Relctr 6.125in I-Beam 3.810in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy 4.8L or 5.3L LS engine. Inside this kit, you'll find a 4.000-inch forged 4140 crankshaft, designed for strength and durability. It also features a 58-tooth reluctor wheel, essential for proper engine management on many LS applications. The assembly includes 6.125-inch long I-beam connecting rods made from robust 4340 steel, which are secured with 7/16-inch ARP 8740 bolts for reliable clamping force under stress.

Complementing the crank and rods are forged 4032 DSS pistons. These are flat-top pistons with a -5cc dish, designed to work with the included plasma-moly file-fit piston rings. The file-fit nature of the rings allows for precise gapping, which is crucial for optimal sealing and performance, especially in naturally-aspirated racing setups. To ensure smooth operation and proper oil clearance, the kit comes complete with King XP series rod and main bearings. This assembly is a well-built foundation for a performance-oriented engine build, particularly for naturally-aspirated racing use.

Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to check all manufacturer installation guidelines before beginning your engine build.
