Eagle Chevy 502 1Pc 4.250in Counterwght Crank 6.535in H-Beam 40cc 4.600in Pistons Rotating Assembly

If you're building a serious performance Chevy 502 big block, this Eagle rotating assembly is a solid foundation. It's designed to handle the kind of stress that comes with exotic fuels, heavy nitrous use, or high boost applications. This isn't your average rebuild kit; it's built for extreme competition engines where reliability under pressure is key.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.250-inch stroke. It features center counterweighting, which helps balance the assembly for smoother operation at high RPMs. Paired with this are Eagle's 6.535-inch H-beam connecting rods, known for their strength. These rods use 7/16-inch ARP L19 bolts, a serious upgrade that ensures they stay securely fastened even under immense load. The pistons are forged 2618 JE units, featuring a 40cc dome and a 4.600-inch bore size, designed to work with the crank and rods for optimal compression and performance. You also get plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's specific needs, and King XP series rod and main bearings to ensure smooth rotation and proper oil clearance.

This assembly is a complete package for those pushing the limits. Keep in mind 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 you get the most out of this heavy-duty rotating assembly.
