King Engine Bearings CS5171HPT HP-Series Performance Coated Camshaft Bearing Set

The King Engine Bearings CS5171HPT is a high-performance camshaft bearing set designed for GM LS engines from 2006-2013, including LS3, LS7, LS9, and LSX applications. These HP-Series cam bearings feature a .775-inch width design and are engineered for racing and performance applications that demand superior durability and reliability.

Advanced Construction and Materials:

• Precision-machined to tight tolerances for controlled oil clearances and reduced bearing pressure
• Constructed from seamless steel tubing with a thin layer of lead-based babbitt material
• Quick-cooled babbitt casting process creates fine grain structure that doubles tensile strength
• Fluoropolymer coating retains engine oil on the surface even under extreme heat and pressure
• Bi-metal construction reduces microscopic deflections for consistent performance

Performance Benefits:

• Superior fatigue strength compared to conventional bearings
• Withstands high racing spring loads while maintaining excellent surface characteristics
• Fluoropolymer coating provides lubrication backup during start-up and momentary oil starvation
• Ideal for racing and high-performance street applications

King Engine Bearings has been a bearing specialist since 1960, and their HP-Series cam bearings are the preferred choice in demanding racing and aviation industries. Each bearing set undergoes rigorous quality control to ensure only the highest quality components reach your engine build.
