Manley Toyota 4.5L 1FZ-FE Exhaust Valve Kit - 34.00mm Head Dia. 99.00mm O/A Length, 0.2740in Stem

When you're rebuilding the top end of your 1993-1997 Toyota Land Cruiser or 1996-1997 Lexus LX450, the valves are critical components. These Manley Race Series exhaust valves are built from XH-426 stainless steel, a well-known material for handling the heat and stress inside an engine. The 34.00mm head diameter and 99.00mm overall length are specific dimensions designed to fit the 1FZ-FE engine, ensuring proper sealing in the combustion chamber.

Beyond the stainless steel construction, these valves feature chrome-plated stems and hard tips. This adds a layer of wear resistance right where the valve guides and rocker arms make contact, helping to extend the life of both the valve and the surrounding components. The under-head area is swirl-polished to help smooth airflow into the cylinder, and the combustion face is fully machined for better efficiency. While these are Race Series valves, they are a solid option for street engines that see regular use, especially if you plan on running higher octane fuels or pushing the engine a bit harder.

This kit includes the exhaust valves needed for your engine rebuild. Always refer to your vehicle's service manual for specific installation procedures and torque specifications when working on your engine.
