Most Wiseco 2-cycle pistons are forged from high-silicone bar stock. Greater strength and lower expansion at high temperatures. Complete piston kits include High-Performance forged pistons, rings, wrist pins, circlips and top-end gasket kit for one complete engine. All Wiseco High-Performance pistons are priced with rings, wrist pins and circlips. Wiseco ring types are not interchangeable (i.e., CD is not interchangeable with LC) and fit only Wiseco pistons. Oversize pistons require cylinder boring.
