These rings help to maintain proper seal and lubrication within the engine.

The piston pin is made of high-strength, chrome-molybdenum alloy steel, ensuring a strong connection between the piston and the connecting rod. The piston pin is also designed with a nut-less piston pin retention system, which simplifies installation and maintenance.

The WiseCo 4999PS Piston Kit includes pistons, piston pins, piston pin retaining clips, and piston rings. This kit is compatible with engines that require a standard 9.5:1 compression ratio, making it an ideal choice for those looking to enhance the performance of their 95ci engine.
