Katech LS9 2.165" Titanium Molybdenum Intake Valve
Katech LS9 2.165" Titanium Molybdenum Intake Valve
Lightweight Titanium Intake Valve Engineered for LS9 Valvetrain Stability and Durability
The Katech LS9 2.165" Titanium Molybdenum Intake Valve is engineered as a direct replacement for LS9 cylinder heads, delivering reduced valvetrain mass, improved high-RPM stability, and consistent performance in demanding street and race applications.
Manufactured from premium titanium alloy, this intake valve significantly lowers reciprocating weight compared to conventional stainless steel valves, allowing for improved valve control, faster acceleration, and reduced stress on critical valvetrain components.
Each valve features a Chrome Nitride coating along with a back cut stem with molybdenum coating to provide enhanced wear resistance and durability.
Updated for 2023, this design retains factory lash cap compatibility, maintaining proper valvetrain geometry in OEM and performance-based builds.
Important! These valves are designed for use with bronze valve guides only. Proper guide material is critical to ensure lubrication, heat transfer, and long-term durability.
