About EngineQuest
Built on Legacy. Driven by Innovation.
EngineQuest is your trusted source for high-quality new engine parts built with precision, innovation, and the real-world insight that comes from decades in the industry. With a strong focus on quality and a deep understanding of what today’s engine builders need, we proudly serve customers in the automotive, performance, marine, industrial, and forklift markets.
Our story began in 1949, when Aaron and Alex Stolberg started sourcing engine and transmission cores in Chicago. Over the years, the business expanded across the country and earned a reputation for reliability, craftsmanship, and service. Our experience in cores and recycling helped shape who we are today, giving us firsthand knowledge of which parts are most in demand and where opportunities for innovation exist.
Today, EngineQuest has entered an exciting new chapter, focusing exclusively on new engine parts from our state-of-the-art facility in Las Vegas, Nevada. This dedicated focus allows us to manufacture a wider range of hard-to-find, discontinued, and specialty components, and to continue our tradition of delivering more than just parts. We deliver solutions.
