Wiseco Pistons 4963M08000 Wiseco 4963M08000 80.00mm 12:1 Compression ATV Piston Kit

Wiseco leads the performance aftermarket by producing the highest quality forged pistons for dirt bikes, ATV's, snowmobiles, outboard marine, and motorcycles in the USA. Wiseco is unique because all pistons are forged in house and all forge tools are produced in the USA. This allows control of all aspects of the manufacturing process from raw bar to skirt coating finished parts. Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable. It 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.
