Overview

They are made from Phosphor Bronze (Cn-Sn-P alloy), chosen for its high tensile strength and superior heat transferring ability. These materials help maintain optimal clearances, reduce stress on the valve train assembly, and prevent seizures and cracking under high stress loads.
Show original supplier description
The Tomei Valve Guide Set is engineered using Phosphor Bronze (Cn-Sn-P alloy), a material selected for its exceptional tensile strength and superior heat transfer capabilities. This is crucial for engines that operate at high power outputs and high RPMs, where extreme heat conditions can accelerate the deterioration of valve train components. The use of this advanced alloy ensures that critical clearances are maintained, reducing stress on the valve train assembly. This not only enhances performance but also helps to prevent seizures and cracking that can occur under high stress loads. This ensures a reliable and long-lasting upgrade for your engine's valvetrain. The Tomei Valve Guide Set is specifically designed for the Nissan Skyline GT-R models equipped with the RB26DETT engine, covering a range of years from 1989 through 2002.
