These Power Forged pistons from Speed-Pro are designed to fit tight, thanks to a special aluminum alloy that doesn't expand as much as other alloys. They'll provide the stability and ring control that you need, plus the strength that you want. Speed-Pro pistons also feature ribbed skirts for better oil retention and even include new wrist pins!
