For over 45 years, Ansen USA has been manufacturing the highest quality American made valve covers. Ansen USA was run for many years by Els Lohn (SEMA Hall of Fame Inductee, 1965) and the design, manufacturing, and distribution facility is still located in Southern California. As a true pioneer of the aftermarket industry, we have continued to build on its long tradition of quality parts, with style and performance to enhance any hot rod, muscle car or classic street machine.
