Eagle Competition Rotating Assembly Kit for Chevrolet/Pontiac LS-Series 4.030in Bore

If you're building a high-performance LS-series engine for serious racing, this Eagle Competition Rotating Assembly Kit is a solid foundation. It's designed for applications pushing the limits, including those using nitrous or forced induction. This kit is built to handle the demands of competition, offering a robust package for your Chevrolet or Pontiac LS engine.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under extreme stress. Paired with it are 6.125-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts, known for their reliability in high-RPM environments. The pistons are forged 4032 aluminum with a -12cc inverted dome design, specifically for a 4.030-inch bore, and come with plasma-moly file-fit rings for a good seal. King XP rod and main bearings are included to ensure smooth operation and longevity for the rotating assembly.

This kit is a comprehensive solution for anyone looking to rebuild or significantly upgrade their LS-series engine for racing. It's engineered to work with a 24-tooth reluctor wheel, common on many LS applications. While this kit is built for performance, please note it is not CARB approved and cannot be shipped to California. It fits a wide range of Chevrolet and Pontiac vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac Firebird.
