Product Descripton:

Take a look back at the company’s humble roots, and rich, racing heritage. In the early days of hot rodding, those who sought optimum performance became innovators, pushing the envelope of speed in the quest for racing glory. Diamond Pistons, founded in 1968–the heyday of muscle cars and drag racing– was born of that innovation and continues today to be a driving force in performance and racing piston design.
