Wiseco 77.0mm Ring Set GNH Ring Shelf Stock - 7700XXFind parts that fit my vehicle

Wiseco piston ring sets are made specifically to Wiseco's specifications to provide ultimate performance and sealing with Wiseco's wide variety of pistons. From compression and sealing to oil control, rings can make or break piston performance, which is why Wiseco rings are developed and tested for race-ready performance.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Piston rings are designed to seal the combustion chamber of your engine so that gasses do not enter the crankcase and oil does not enter the combustion chamber. If your engine is burning oil, losing compression, or if you are rebuilding your engine, it is recommended that you replace your piston rings.
