About Speed Pro street series power forged pistons:
Higher compression, longer life.
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 you need, plus the
strength you want. Speed-Pro pistons also feature ribbed skirts for
better oil retention, and even included new wrist pins!
