Description

Big Twin engines demand gaskets that won't fail under sustained high-combustion pressures—and stock gaskets simply aren't engineered for the abuse. S&S Cycle's Big Bore gaskets combine aramid fiber reinforcement with a stainless steel fire ring to deliver the sealing integrity and durability your engine needs for reliable power, whether you're on the dyno or the street. Built in the U.S.A. with proven materials, these gaskets resist extrusion and blow-out failures that can cost you an engine.

  • Aramid fiber-reinforced graphite
  • Steel core construction
  • Stainless steel fire ring
  • Anti-stick coating included
  • Pro-Formance micropore compound (base)
  • Extrusion-resistant design
  • Blow-out resistant material
  • Made in U.S.A.
  • Fits Big Twin 90–1918
  • Head and base gasket set

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
