Overview

We chose to use Phosphor Bronze (Cn-Sn-P alloy) to make our Valve Guides, for its highly tensile and superior heat transferring ability, which is vital in high power and high RPM outputting engines. Since race engines these days require more power at higher RPM use , these engines now experience more extreme heat conditions. These conditions will increase the deterioration rate on these valve train related components. The Phosphor Bronze material has exceptionally lower friction and the best possible clearances can be maintained, which will reduce the stress on the valve train assembly, prevent seizures and cracking under high stress loads. Features: - Designed to deliver trouble-free, consistent performance - Right for your vehicle and lifestyle - Made from high-quality materials for ultimate durability - Manufactured to meet or exceed strict quality requirements
