Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and heat resistance
  • 3.625" bore diameter for precise fitment on Big Twin engines

Cometic gaskets are engineered using advanced materials and manufacturing processes to deliver race-proven performance. The MLS design features multiple layers of stainless steel with elastomeric coatings that conform to sealing surfaces, compensating for minor imperfections while maintaining excellent torque retention. Ideal for engine rebuilds, performance upgrades, and stock replacement applications.

This was the first time I had ordered from Boatplicity, not having come across them in my previous searches for gear. As what I was looking for was a brand name product I selected purely based on price. The purchase process went seamlessly and the two items I bought showed up within a day of each other, both well within the delivery date promised. The items were well packaged and arrived undamaged, and were exactly as I had ordered and expected.

Easy to find item, and very user friendly checkout.

Delivery was very fast. I didn't expect to receive it so soon.

best price and fast checkout.

Shopping was easy. Just have to wait for the order to arrive.

great
