Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in I-Beam Rods 3.903in Pistons Rotating Assembly

Eagle is well-known for building strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS1 engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of performance. It’s a complete package that brings together the core rotating parts you need to get your LS1 project moving forward.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, chosen for its strength and durability under high stress. It’s paired with 6.125-inch I-beam connecting rods made from robust 4340 steel, secured with 7/16-inch ARP 8740 bolts. These rods are built to withstand the forces generated in a performance racing application. The assembly also includes forged 4032 DSS pistons with an inverted dome design, measuring 3.903 inches in diameter. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to ensure optimal sealing and performance. To round out the package, King XP rod and main bearings are included, offering excellent load-carrying capacity and wear resistance.

This rotating assembly is specifically intended for naturally-aspirated racing use. Please note that this part is not CARB approved and cannot be shipped to California. It's crucial to check all manufacturer installation instructions and specifications before assembly to ensure proper fitment and performance in your specific build.
