These are our special ModMax 4.6 STROKER Pistons. They are designed to fit with our stroker crank of 3.750" stroke and our special STROKER connecting rods of 5.850" length. These are the 17cc Dish Volume version. Check to see your compression ratio below. These pistons are engineered to take the most boost, horsepower and abuse your Modular engine can give them. They are manufactured from 2618 heat treated space aged aluminum with low silicon to make them durable and light weight. These pistons are fully CNC machined with exact tolerances and unique skirt designs to give low noise and better ring seal. The ring lands are thick and lowered to keep strength and stiffness under high cylinder pressures. The diamond turned skirts are setup to run .0035" clearance for up to 2000hp applications and can be run even tighter in street or lower horsepower environments. They are full floating design with .866" wrist pins and include double spirolox and super strength pins. If you are serious about power and having a piston that will hold up, these are the original and the toughest you can buy period!
