The Cometic MLS Head Gasket for the 1991 and up Lexus LS400 4.0L 1UZ-FE is a high-performance sealing component designed to withstand demanding engine conditions. Constructed with three layers of stainless steel, this gasket offers enhanced strength, excellent rebound properties, and superior corrosion resistance. The outer layers are embossed and coated with a Viton rubber-based material, which is heat resistant up to 2500°C (4820°F), ensuring reliable sealing in harsh environments. The gasket's multilayer design provides durability and a consistent seal, making it suitable for high-performance applications and demanding engine rebuilds. Its precise bore size of 92.5mm ensures proper fitment and sealing integrity for the specified engine.

This gasket is engineered specifically for the 1991 and newer Lexus LS400 models equipped with the 4.0L 1UZ-FE engine. It is a direct replacement for OEM head gaskets, offering a reliable upgrade for performance or rebuild projects. Installation involves standard head gasket replacement procedures, and the kit includes the gasket itself with no additional components listed. Ideal for street, performance, and restoration use, this MLS gasket ensures a durable seal under high compression and heat conditions, maintaining engine integrity and performance over time.

Overview

The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
