Gas Porting Drill Fixture Kit & Replacement Parts
Virtually eliminate side ring clearance by drilling gas ports in your piston ring lands. These tiny ports apply compression pressure directly to the back of the ring, pushing it against the cylinder wall with greater force while minimizing compression leakage. Gas ports work best with piston-compression heights of 1.2" or less on engines running at high RPM (7,000 or higher).
These simple tool kits take all of the guess work out of gas porting and include everything you need to get started.
