Designed for enthusiasts and professionals alike, this set of five main bearings is engineered to withstand the rigors of high-performance driving, ensuring your engine runs smoothly and efficiently.
**Key Features and Benefits:**
- **Advanced Alecular™ Technology:** The bearings feature a unique Alecular™ bi-metal structure, combining an aluminum-tin-silicon alloy top layer with a high-strength steel back. This innovative design resists surface migration and extrusion, even under extreme loads, making it ideal for demanding applications like drag racing and monster truck competitions.
- **Durability and Strength:** Built to endure high loads for short durations, these bearings offer exceptional durability. The harder-than-Babbitt material ensures longevity and reliability, providing peace of mind during intense driving conditions.
- **Enhanced Compatibility:** Perfectly suited for performance applications, these bearings are compatible with nodular cast iron crankshafts. Whether you're hitting the street, strip, or circle track, they deliver the performance you need.
- **Wide Fitment Range:** Designed to fit a variety of Subaru engines, including 1.6L, 1.8L, 2.0L, 2.2L, and 2.5L models, as well as Saab 2.5L engines, offering versatility and convenience for multiple applications.
- **Improved Engine Performance:** By reducing friction and wear, these bearings help optimize engine performance, ensuring smoother operation and increased efficiency.
Elevate your engine's capabilities with the King SI-Series Main Bearing Set, and experience the difference in performance and reliability. Whether you're a weekend warrior or a professional racer, these bearings are your ticket to superior engine performance.
Our TechLab R&D culture focuses on constant analysis of what can be done to support ever increasing race engine loads, and how to improve bearing durability.
One of those technologies is Alecular?.
KING developed the HP Series utilizing the Alecular? bi-metal structure. It consists of an aluminum|tin|silicon alloy top layer bonded onto a high strength steel back. Major benefits of the Alecular? structure are its ability to resist surface migration and extrusion under very high loads, including metal-to-metal contact, over short durations of time. Such conditions may be found in drag racing and monster truck competition.
The HP series was developed mainly for drag race and monster truck applications needing a material that is harder than a Babbitt top layer. These applications require a structure that can withstand high loads for short durations and still offer higher embedabilty and compatibility. In response, KING developed the HP Series featuring the Alecular? bi-metal structure.
The HP series is also suited for many performance applications using nodular cast iron crankshafts, such as street, strip and some levels of circle track racing.
