Eagle Chrysler RB 4.150in Crank 6.760in H-Beam -29cc 4.375in Pistons Rotating Assembly

This is the Eagle Chrysler RB 4.150 inch crankshaft, 6.760 inch H-beam connecting rod, and 4.375 inch piston rotating assembly. It's a complete package designed for serious performance builds, especially those looking to handle the demands of racing, nitrous, or forced induction setups. If you're rebuilding the heart of your RB-powered Mopar and need a strong, reliable foundation, this assembly is built to take on significant power.

At its core is a forged 4340 steel crankshaft with a 4.150 inch stroke, providing the foundation for increased displacement and torque. Paired with this are 6.760 inch H-beam connecting rods, known for their strength and ability to withstand high RPMs and heavy loads. These rods use 7/16 inch ARP 8740 bolts, a popular choice for their reliability under stress. The pistons are forged 2618 JE units, featuring an inverted dome design with a -29cc volume to achieve a specific compression ratio, and they measure 4.375 inches in bore size. This assembly also includes plasma-moly file-fit rings, which allow for precise ring gap setting to match your build's specific needs, and King XP rod and main bearings, offering robust lubrication and wear resistance.

This rotating assembly is a well-built option for those pushing the limits of their RB engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Ensure you consult with your engine builder to confirm compatibility and proper installation procedures for your specific application.
