ABOUT US | History | Parts | Inventory

The Company...Our long tradition relating to engines started in 1952 when Don Gross, an aircraft mechanic, began a career in the automotive aftermarket. Don worked for numerous industry leaders and in 1973 purchased Steven Motor Parts in LA and began distributing wholesale auto parts. Don’s sales agency continued to grow, representing industry giants like Nylen, Ertel, and Sterling. In 1982 Don opened a second location in San Diego, CA. In 1998 the company joined the Engine Parts Group, a buying and marketing group operated by 12 of the largest engine parts distributors in North America. In 2015 the company opened the third distribution point in Riverside, California.
In 2021 the company doubled in size after acquiring Sterling Bearing, Inc., a well established warehouse distributor with locations in the Midwest, North East, and South East. Sterling “Bearing” began operations reconditioning babbitted connecting rods in 1936. As times and technology changed the company shifted production to crankshaft remanufacturing.
In the early ‘70’s Sterling began distributing parts and in 1975 introduced one of the first engine kits in the USA, BLOCKMASTER. Sterling continued to operate a full-service machine shop and production crankshaft plant until 1994 when the company shifted all its resources to distributing engine parts and remanufactured engine components. The company opened a warehouse in Minneapolis in 1999 and continued expanding by buying warehouses in key markets, including: Worcester, MA; Dania Beach, FL; Pittsburgh, PA. Today we operate 7 engine part specialty warehouses.
