Silv-O-Lite Hypereutectic Pistons
Get the most from your hard-earned dollars with Silv-O-Lite hypereutectic pistons. These pistons utilize aluminum alloy high in silicon for greater strength plus scuff and seizure resistance. Silv-O-Lite pistons have improved groove wear and resist cracking in the crown area where operating temperatures are severe. Silv-O-Lite hypereutectic pistons feature reinforced top lands and their proprietary process of diamond finished skirts. These aftermarket pistons are available for many applications from your light truck to your auto or import. Spend wisely and choose replacement pistons that will work hard for you--Silv-O-Lite hypereutectic pistons.
