4-1/8 S&S SUPER SIDEWINDER MLS™ HEAD GASKETS

Finally!!  An answer to head gasket issues with big bore V-Twins.  A new kind of gasket!  Developed to withstand more power per cylinder, higher operating temperatures, and thinner head and block castings.  Ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.  Two viton coated outer embossed spring steel layers with a steel inner layer provide support to the gasket allowing multiple thicknesses.  Withstands the shearing forces created by aluminum heads on cast iron blocks.  Retains torque (once the gasket takes a torqueset, re-torquing is not required).  MLS gaskets are stronger, more forgiving, and capable of sealing despite extreme horizontal and vertical motion between the head and block.

• Survives higher combustion pressures    
• Functions at a wider range of operating temperatures
• Developed to overcome sealing challenges
• Solid steel construction retains torque well and does not take a compression set like composition gaskets.
