Product Details

The Eagle 12143040 is a complete rotating assembly engineered for 8-cylinder engines. Eagle Specialty Products is a trusted name in high-performance engine building, offering precision-matched rotating assemblies that are designed to deliver superior balance, durability, and power output compared to stock components.

A rotating assembly (also referred to as a "rotating kit" or "rotating group") typically includes the crankshaft, connecting rods, and pistons — all matched and ready for assembly. Eagle's assemblies are manufactured to tight tolerances, reducing the need for extensive blueprinting work and making them a popular choice for engine builders working on performance street, strip, and racing applications.

Key Features:

  • Designed for 8-cylinder engine applications
  • Precision-machined components for tight tolerance fitment
  • Engineered for improved strength and durability over OEM rotating components
  • Components matched as an assembly for reduced vibration and improved balance
  • Suitable for high-performance street, strip, and competition builds
  • Manufactured by Eagle Specialty Products, a leader in performance engine components

Eagle rotating assemblies are a go-to solution for engine builders looking to upgrade internal components with a cohesive, pre-matched kit. Always verify specific bore, stroke, and rod length specifications to confirm suitability for your engine build before installation.

just placed the order, ask me later

I found that boatplicity had the best price I could find on the Scotty rod holders and mounts that I needed. I had never ordered from or heard of them before. But I took a chance and placed an order with them anyway because of the lowest price. I was pleasantly surprised! Everything went GREAT!!! I would buy from them again!!! (I do think I should have gotten free shipping on an order that was over $100.00 but I did not.)

The product description was spot on which helped me determine it was the right item for me. The item was a very reasonable price. Shipping was prompt. I would recommend this vendor to a friend and would purchase from them again.

On time, free shipping, easy shopping

None

The shopping was easy. I was able to look up the specs easily.

The order got here later then it should have because I paid for faster shipping. Other then that everything looks good.

Excellent and easy to order
