749193 Valve in Xl1200 Xb9 12 7MM Stem 1 851 X4

When you are looking to maximize performance in your Harley-Davidson engine, these AV&V tulip-style high-flow valves are the gold standard. Forged from a single piece of racing-grade stainless steel alloy, they offer some of the highest flow rates available on the market today. We often see wear on valve tips in high-lift setups, but these feature a bearing-quality hardened tip to prevent that premature breakdown. The 5/16-inch stems are centerless ground to a micro finish for smooth operation and longevity, and they include a 45-degree angle below the lock groove to make seal installation a breeze. These valves are a perfect upgrade for Single, Sportster, Buell tube frame, and XB models where airflow is the priority.
