KB PERFORMANCE Piston Kit - XL KB292.030

If you're building a high-performance engine that demands precision and reliability, KB Performance pistons are engineered to deliver both. The KB292.030 kit uses T-5 heat-treated 390 hypereutectic aluminum to handle the thermal and mechanical stress of serious racing, while diamond-machined tolerances ensure consistent fit and longer component life. With tighter clearances than standard pistons, you'll get reduced piston rock, better ring seal, and the durability that separates a competitive engine from one that fails under load.
