With over 25 years of experience in the manufacturing of titanium products, the Del West brand represents the worldwide standard for advanced titanium valve technology. Every aspect of the design and production of Del West titanium valves clearly sets us apart from the rest of the industry. No other titanium valvetrain manufacturer can claim an association with more championships in every major professional racing series worldwide, including Formula 1, CART, IRL, NASCAR, WRC, Trans-Am, World Superbike, off-road racing, NHRA/IHRA, offshore marine and more! All valves are completely CNC machined and precision ground. All critical dimensions of the valves are controlled 100% for visual and dimensional aspects before shipment. Del West applies in-house developed thermally sprayed coatings to protect against wear on the stem. The tip of the valve is protected by either the insertion of a steel tip or with a thermally sprayed coating. Del West can apply thin film coatings such as Physical and Chemical Vapor Deposition (PVD, CVD). These types of coatings include Diamond-Like Carbon (DLC), Titanium Nitride (TiN), and Chromium Nitride (CrN). They are recommended to be applied to any surface of a component where increased wear protection and extended service are required. a Del West engineer can help guide you on the performance benefits to applying these coatings. 100% traceability on all components from receipt of material to shipment of product is maintained at Del West. The lower mass of the titanium valves combined with the matching Del West keepers (locks, cotters) and spring retainers allow for the use of higher RPM and more aggressive cam profiles without the loss of valve control. This results in the development of broader torque curves with increased horsepower and higher RPM and power numbers.Pit Stop USA offers Del West 11/32" Titanium Intake Valves - 2.180", + .600" Long, Radius Groove - (Set of 8) IV2180-6T-8 at low everyday prices.
