KB Performance Piston and Ring Sets: Strong Made Affordable

  • thumbnail

Premium hypereutectic pistons ideal for high performance street, bracket racing, and marine engines.

Why They’re Cool: KB Performance pistons are made from 390 aluminum alloy and heat-treated to T5 standards. That makes them 30 percent stronger than untreated hypereutectic pistons. The KB Performance pistons also have a lightweight, rigid-rib skirt design that helps stabilize the piston in the bore—no rocking or slapping. With over 1,300 different part numbers available, Summit Racing has a KB Performance Piston and Ring set for your American V8.
