COMETIC StreetPro Kits cater to the budget-minded street-rodder who is looking to purchase a kit with all necessary gaskets and seals needed for their rebuild. Quality gasket materials are a priority in StreetPro kits. Kit materials include: MLS, AFM, Aramid Fiber, and Armor Clad.

-   The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
-   The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements
-   MLS Gaskets are comprised of multiple embossed layers of both AMP (Advanced Multi-Polymer Coating) and uncoated stainless steel
-   Requires less clamp load creating less bore distortion
-   Conforms load distribution across the sealing area
-   Quality Gasket Materials
