The KB Series pistons are high-performance, marine grade and designed for performance applications. With a 1% silicon content they're also strong enough to be used in drag racing or circle track car tracks without worrying about metal fatigue causing fractures on overuse; there's no need with this product! The 100% CNC machined crowns provide greater durability while staying true under pressure because of its spiral lock retainer grooves which allows these engines not just tolerate but excel at abuse thanks their superior design. With their lightweight, rigid-rib skirt design pistons that stabilize the bore and a variety of options designed for your vehicle's application. With all these benefits plus improved oil control you won't have to worry about cold start ups knocking or paying an arm & leg!
