About this part

Product Details

Built around a 3.800-inch stroke crankshaft, this Eagle rotating assembly is specifically designed for Chevy 4.8L and 5.3L LS engines. The crankshaft features a 24-tooth reluctor wheel, making it compatible with the factory ECU for 1997-2006 LS applications. This is a serious piece for anyone building a performance engine, whether for drag racing, road racing, or even street applications that demand more than stock.

The assembly includes 6.125-inch long H-beam connecting rods, known for their strength and ability to handle higher RPMs and increased cylinder pressures. These rods are paired with 3.780-inch bore pistons, completing the core of the rotating assembly. Eagle uses robust materials and proven designs to ensure these components can withstand the rigors of competition use, including forced induction and nitrous oxide systems. This means you can push your engine harder, knowing the rotating assembly is built to take it.

When assembling a high-performance engine, the rotating assembly is the heart of it all. Choosing a well-built set like this from Eagle takes a lot of the guesswork out of selecting compatible, strong components. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your build.
