These pistons are designed using our FSR (Forged Side Relief) forgings featuring internal and external cavities to minimize weight while providing a more rigid construction. The FSR design reduces skirt width helping to minimize piston contact with the cylinder wall that can cause friction and power loss. With thousands of race miles logged in the most demanding applications like NASCAR and the IRL, these pistons provide the ultimate combination of low friction lightweight design with increased stability and strength. (Tech note: In extreme horsepower applications the use of oil squirters may be required)
