2413cc Big Bore Piston Ring Set - 104mm Bore Type 4 Engines

Replacement 104mm piston ring set specifically for Big Bore Type 4 engines enlarged to 2413cc. Designed only for engines running 104mm barrels and pistons—this set is not suitable for standard 94mm or 96mm builds.

Ideal during a refresh or full rebuild where worn rings are causing low compression, oil consumption, blow-by, or crankcase pressure issues. Manufactured to suit high-capacity Type 4 engines, helping restore proper sealing and long-term reliability.
