Spi Hyperdryve Piston Kit SM-109287

THE NEXT STEP IN THE EVOLUTION OF PERFORMANCE PISTONS. The high temperature resistance significantly improves fatigue strength and impact toughness. This new alloy, combined with the already existing techniques of anodizing the crowns, machine smoothed heads and MOS2 coated skirts for smoother start-ups and break-ins, meets the demands for today's high performance engines.

Includes:

• 1 piston
• 1 ring set
• 1 wrist pin
• 1 circlip set
• Made from space age aluminum alloy which maintains it's high tensile strength up to 700 degrees F, 50% higher than a cast piston.
• This kit is standard bore - standard bore size for these sleds is 85.00mm.
• Made in Taiwan
