Its design allows for a tighter fit in the piston, reducing side-play and improving engine performance. The wrist pin also features a roller-tip design that reduces friction and improves piston ring sealing.

The piston kit comes complete with a set of high-quality, ring packs. These rings are made from a nitrided, chrome-molybdenum alloy that provides superior wear resistance and sealing ability. The ring pack includes a compression ring, oil control ring, and two piston rings.

In summary, the Pro-X 8457-P139492-ATV piston kit is an ideal upgrade for those seeking to enhance the power and efficiency of their 2003-2005 Gas Wild HP 300 ATV.
