ATHENA (MLS) Multi Layer Gasket

Material

ATHENA MLS gaskets consist of 3 to 5 layers made from various raw materials, designed to perform at higher compression levels than stock configurations. The type of steel used varies based on engine requirements. These gaskets provide an even torque load across the sealing surface, compensating for any bore distortion. They are suitable for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

Manufacturing Process

Athena MLS Head Gaskets are crafted from high-grade 301 stainless steel. Each layer is laser cut and embossed through an optimized formation process. Two head gasket layers undergo a stress-relieving process to minimize embossment-induced stress. A proprietary two-part polymer coating is applied post-stress relief, ensuring uniform coverage of the outer layers and maintaining a micro seal for engine coolant and oil fluids. These gaskets are rigorously tested on engine dynos and endurance performances.

Gas Stopper Technology

This technology is crucial for racing MLS head gaskets. The stainless-steel stopper layer features an “active fold” design that creates a high-pressure seal around the cylinder bore when the cylinder head is tightened. This design allows for tighter clamping of the cylinder head and engine block, preventing gas leaks from the combustion chamber and reducing component distortion through quicker temperature equalization.

Benefits

• Superior sealing properties under high pressure conditions
• Higher elasticity and constant load resistance
• Optimized load balance
• Improved engine performance
• Longer durability

Proprietary Coating Technology

The two-part polymer coating ensures uniform coverage of the outer layers, providing a micro seal for engine fluids and withstanding harsh environments. The first layer is a high-temperature compound that conforms to irregularities in the engine block deck and cylinder head surfaces, sealing finishes up to 60 Ra. The second layer releases easily, preventing sticking to mating surfaces during engine disassembly.
