Precision Engine Valve Train Components Manufacturer
Founded in 1982 by engine component manufacturing professionals, SI Valves has established itself as a trusted global supplier of premium valve train components. Our expertise lies in producing specialized components for diverse applications including racing, high-performance street vehicles, diesel engines, motorcycles, and power sports equipment. In 2009, we expanded our capabilities through the acquisition of Valve Train Manufacturing (VTM), enabling in-house production of critical components like valve guides, seats, and keepers at our California facility. Our commitment to quality is demonstrated through the use of premium materials such as race-proven stainless steel alloys, Inconel, and titanium, combined with advanced manufacturing techniques like swirl polishing and DLC coating.We maintain extensive inventory for popular engine platforms including Chevrolet LS/LT series, Ford Modular engines, Chrysler Hemi, and Porsche models while offering custom manufacturing capabilities for specialized requirements. Our second-generation family leadership ensures long-term focus on serving individual engine builders with competitive pricing and timely delivery, distinguishing us from corporate conglomerates prioritizing short-term profits. With over four decades of industry experience, we provide technical expertise and personalized support through our dedicated team of professionals including Chris, Pete, and Steve, who collectively represent decades of specialized knowledge in valve train engineering.
