Eagle Buick 3.8L V6 Internal Balance Rotating Assembly Kit w/ Upgraded Piston Pins

If you're rebuilding the heart of your Buick 3.8L V6 for serious performance, a strong rotating assembly is where it all starts. This Eagle Competition Rotating Assembly kit is built to handle the stress of racing, including setups with nitrous or forced induction. It's a well-built foundation for a powerful engine.

This kit features a 3.625-inch forged 4140 steel crankshaft, designed for durability under high loads. Paired with it are 6.300-inch H-beam connecting rods, known for their strength and reliability in performance applications. These rods use 3/8-inch ARP 2000 bolts, a popular choice for their robust clamping force. The included pistons are forged 2618 aluminum with an inverted dome design, featuring a -26.2cc dish and a 3.819-inch bore size. You also get upgraded piston pins for added strength, plasma-moly file-fit rings, and King XP rod and main bearings to ensure smooth operation and longevity.

This assembly is balanced internally, which can simplify balancing procedures for your engine build. Keep in mind that this kit 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.
