Wiseco 40050M08650 Piston Kit Size: 86.50mm
Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will
stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. Armor Glide Coatin 56-W4005+050.PX of the art CNC equipment and use the same low-expansion, low-friction piston alloy all major Japanese engine manufacturers use. - Uses an OEM style tin coating to assist the break-in process when you first start your machine.

ArmorGlide skirt coating, which is the result of testing, development, and benchmarking through Wiseco?s rigorous in- house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide? a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore
