Eagle Buick 3.8L V6 3.400in Ext Balance Crank 5.967in H-Beam 3.820in Pistons Rotating Assembly

When you're building a high-performance Buick 3.8L V6, a strong rotating assembly is the heart of the operation. This competition rotating assembly from Eagle gives you the core components you need to build a powerful engine, whether for drag racing, road racing, or serious street performance. It includes a forged 4140 steel crankshaft, H-beam connecting rods with ARP 2000 bolts, and custom-spec JE pistons designed for boosted or nitrous applications.

The 3.400-inch stroke forged crankshaft is externally balanced, making it straightforward to set up for your specific application. Paired with the 5.967-inch H-beam connecting rods, which feature 3/8-inch ARP 2000 bolts, this assembly is built to handle significant stress. The included JE pistons are forged from 2618 aluminum and feature an inverted dome design with a -28.6cc dish, along with plasma-moly file-fit rings, to optimize for forced induction or nitrous oxide. King XP rod and main bearings are also included, offering robust protection for these critical components.

This assembly is designed for demanding use, including nitrous and forced induction setups. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
