Key Features:

King Engine Bearings incorporates advanced technology and materials to maximize bearing life and engine protection. Key features include:

• PMaxBlack Polymer Coating: A specialized polymer coating from King’s racing line that reduces friction and wear, enhancing bearing durability.
• Radialock Design: Ensures optimal crush height for precise bearing fitment and improved stability under load.
• Tri-metal Copper-Based Material: Provides excellent fatigue resistance and conformability, critical for high-performance engines.
• Superior Load Capacity: Engineered to handle increased stresses from performance driving and tuning modifications.
• Precision Manufacturing: Tight tolerances and quality control ensure consistent performance and reliability.
• Direct Fitment: Designed specifically for the Subaru FA20 and Toyota 4U-GSE engines, guaranteeing proper installation and compatibility.

Construction & Design:

The King Performance Main Bearing Set is constructed using a tri-metal copper-based alloy that balances strength and flexibility to withstand the rigors of high RPM and heavy load conditions. The polymer PMaxBlack coating reduces metal-to-metal contact, minimizing wear and extending bearing life. The Radialock feature ensures the bearing maintains the correct crush height, which is essential for maintaining oil clearance and preventing bearing movement during engine operation. This combination of materials and design elements results in a bearing set that offers both durability and precision fitment.
