SEMA Specialty Equipment Market Association


A love for cars, trucks and SUVs is the motivating force behind the Specialty Equipment Market Association (SEMA) serves the needs of manufacturers, distributors, retailers, publishing companies, auto restorers, street-rod builders, restylers, car clubs, race teams and others involved in the automotive aftermarket.



SEMA was originally formed in 1963 by a small group of manufacturers as the Speed Equipment Manufacturers Association. The name was changed in 1967 to Specialty Equipment Manufacturing Association and then to the Specialty Equipment Market Association in 1979 for inclusion of non-manufacturing members within the supply chain and surrounding the industry sector.


SEMA sponsors the largest automotive aftermarket conference and trade show annually in Las Vegas, NV drawing over 70,000 buyers and more than 2,000 exhibitors. SEMA sponsors many international events and smaller events as well as virtual events listed on their website.


SEMA members represent a cross-section of multiple industries but a great number of members are still manufacturers of automotive and transportation products. These tend to be aftermarket manufacturers with very little overlap into OEM manufacturing suppliers.


SEMA offers its 6,600+ member companies a variety of business tools and resources to help their business succeed and prosper. Members include manufacturers, retailers, jobbers, distributors, reps, installers, media publications and others interested in the specialty equipment automotive aftermarket.


SEMA publishes a magazine and newsletters for members and a ton of research reports and studies for members.
