Eagle Tall Deck Crankshaft 4.750 Stroke Model 450247506600

Description

Product Overview

The Eagle Tall Deck Crankshaft is engineered for high‑performance automotive applications, combining precision machining with durable materials to meet the demanding needs of racing and performance enthusiasts. Constructed from forged steel, the crankshaft features a 4.750‑inch stroke that increases displacement and torque output, while the 2.200‑inch rod journal provides a solid bearing surface for heavy‑duty connecting rods. Internal balance is achieved through a center counterweight system, complemented by a 2300‑gram bobweight that minimizes harmonic vibration across a wide RPM range. The early‑style two‑piece rear seal offers superior oil control, reducing the risk of leaks and ensuring consistent lubrication under extreme conditions. With a weight of 79.8 pounds, the component balances strength and manageability, making it suitable for both street‑legal builds and track‑only machines. The Eagle brand, known for its rigorous quality standards, guarantees that each crankshaft passes comprehensive testing before leaving the factory, providing confidence in reliability and performance.

Usage

This crankshaft excels in a variety of performance scenarios, from drag racing to endurance road racing, and is equally effective in high‑output street builds. Its tall deck design accommodates longer connecting rods, allowing engine builders to achieve optimal rod‑to‑stroke ratios that improve mechanical efficiency and reduce side‑load on bearings. The robust internal balance system makes it ideal for engines that operate at high RPMs, where vibration control is critical to prevent premature wear. Installers will find the crankshaft compatible with a range of aftermarket and OEM engine blocks that support tall deck configurations, making it a versatile choice for custom engine assemblies. Whether you are upgrading a classic muscle car, a modern sports car, or a purpose‑built race engine, the Eagle Tall Deck Crankshaft provides the foundation for increased horsepower, smoother power delivery, and enhanced durability. Proper installation with high‑quality bearings and torque specifications will maximize the benefits of this component, ensuring that the engine performs reliably under the most demanding conditions.

FAQ

What engine blocks are compatible with the Eagle Tall Deck Crankshaft?

The crankshaft is designed for tall‑deck engine blocks that can accommodate a longer rod length and increased deck height. It fits most aftermarket performance blocks that specify a tall‑deck configuration, as well as certain OEM blocks that have been modified for increased deck height. Always verify the block’s specifications and clearances before installation.

How does the internal balance system improve engine performance?

The internal balance system uses a center counterweight combined with a 2300‑gram bobweight to counteract the rotating mass of the crankshaft. This reduces harmonic vibrations, especially at high RPMs, leading to smoother power delivery, less stress on bearings, and extended engine life. Balanced rotation also helps maintain consistent oil pressure and temperature.

Can the crankshaft be used in both street and race applications?

Yes, the Eagle Tall Deck Crankshaft is versatile enough for both street‑legal builds and dedicated race engines. Its robust construction, balanced design, and reliable sealing make it suitable for daily driving, high‑performance street cars, and competitive racing environments. Proper tuning and supporting components will ensure optimal performance in any application.

What maintenance is required to keep the crankshaft in optimal condition?

Regular oil changes with high‑quality synthetic oil, monitoring oil pressure, and inspecting bearing wear are essential. Ensure that the rear seal is inspected for signs of wear or leakage during routine maintenance. Following the manufacturer’s torque specifications during installation and using recommended bearing kits will also help maintain the crankshaft’s performance over time.

Is there a warranty or guarantee on this crankshaft?

Eagle provides a comprehensive warranty that covers material defects and workmanship for a specified period after purchase. The warranty terms are outlined in the product documentation and can be extended with optional service plans. For any issues, contact Eagle’s customer support for assistance and possible replacement.
