The gear facing fabric is made from Aramid fiber instead of standard Nylon to slightly increase the tensile strength
We chose to use Phosphor Bronze (Cn-Sn-P alloy) to make our Valve Guides
■ Advanced Oil Tempered Chromium-silicone Alloy Steel CoreOil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further
5mm to 15 micromillimeter thin of manganese phosphate coating on its surface to prevent from direct contact with other metal parts while realizing smooth operation
with the correct figure being at 10~20% of the torque applied
Tomei VALVE GUIDE SET For SKYLINE GT-R RB26 163046 COMPLETE HEAD The gear facing fabric isWe 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
