For those looking to maximize their engine's breathing, these AV&V tulip-style high flow valves are the ultimate solution. Forged from a single piece of racing-grade stainless steel, they are engineered to provide the highest flow rates on the market. To ensure longevity under high-lift cams, each valve stem is topped with a hardened, bearing-quality tip. The 5/16-inch stems are centerless ground to a micro finish and feature a 45-degree angle below the lock groove, making the installation of valve seals much simpler. These heat-treated valves are designed for durability and performance, fitting Sportster, Buell RS, Single, Tube frame, and XB models.
