What MEMA Aftermarket Suppliers is
MEMA, The Vehicle Suppliers Association, is the leading North American trade association for vehicle suppliers, parts manufacturers and remanufacturers, representing more than 1,000 member companies across the vehicle supply chain, from original equipment to aftermarket, from light vehicle to commercial vehicle.
MEMA Aftermarket Suppliers is the membership group within MEMA that exclusively serves manufacturers of aftermarket components, tools, equipment and related products. It was formed in January 2023 when MEMA consolidated its former aftermarket divisions, including the Automotive Aftermarket Suppliers Association (AASA), the aftermarket side of the Heavy Duty Manufacturers Association (HDMA) and the Motor and Equipment Remanufacturers Association (MERA), into one group. Members span the light vehicle, commercial vehicle and remanufacturing sectors of an industry that supports more than 900,000 American jobs in all 50 states.
For a company like SPNA, the heavy-duty side is what matters most. MEMA Aftermarket Suppliers runs councils and peer networks built specifically for the commercial vehicle aftermarket, including the Heavy Duty Manufacturers Representatives Council and the Commercial Vehicle Aftermarket Sales Professionals Network, and provides members with market research, advocacy and industry events throughout the year.
Why SPNA joined
SPNA is the U.S. distribution arm of Sertplas, a Turkish manufacturer that has built commercial vehicle electrical and air-connection components since 1955 and has been a Tier-1 supplier to Daimler Truck AG since 2018. We opened in Farmington, Michigan to bring that same OE-grade product to the North American aftermarket: 3-in-1 airpower lines, 7-way ABS cable assemblies, air brake lines, gladhand parts, and trailer plugs and sockets, all stocked locally and built to the North American standards, with 7-way assemblies to SAE J560 and SAE J2394 and 3-in-1 air lines to FMVSS 106.
Being new to a market is not a reason to stand outside its institutions. It is a reason to join them. MEMA Aftermarket Suppliers is where the heavy-duty aftermarket's suppliers, distributors and channel partners set expectations, compare notes on the market, and meet face to face. We joined for four practical reasons.
Industry events
MEMA brings its member community together throughout the year, from webinars to conferences and trade shows. Membership gives SPNA access to those events and discounted participation as a supplier.
Industry standards and research
Members get access to MEMA's market research and to the councils where commercial vehicle aftermarket practices are discussed. That helps us build and stock the right parts.
Peer networks
MEMA's councils and networking groups consistently rank among the most valuable member benefits. The Commercial Vehicle Aftermarket Sales Professionals Network is built for exactly the work our team does every day.
A voice for suppliers
MEMA advocates for the supplier industry in Washington and with the wider industry. As an importer and distributor navigating tariffs, standards and supply chains, we want a seat at that table.
"Sertplas has supplied truck OEMs for seventy years. Joining MEMA Aftermarket Suppliers puts SPNA inside the organization that the North American heavy-duty aftermarket actually runs on, and it holds us to that industry's expectations from day one. That is exactly the kind of accountability we want our customers to see."
Ross Serter, General Manager, Sertplas North America
What it means for our customers
If you buy from SPNA today, nothing changes about the parts, the pricing or the way we ship from Farmington. What changes is what stands behind the company you are buying from.
- For distributors and buying groups: your supplier is a member of the same association many of your other suppliers belong to, and works within the industry's shared standards and practices. That makes onboarding a new line simpler.
- For fleets and repair shops: the tractor-trailer cables and air lines you install are made by a Tier-1 OEM supplier and distributed by a company that is part of the North American aftermarket's professional community, not operating outside it.
- For everyone: we are closer than you might expect. MEMA keeps a regional office in Southfield, Michigan, about 12 miles from our warehouse, and we are on the road to the same events you attend.
Where to find us
SPNA participates in MEMA Aftermarket Suppliers events and industry gatherings throughout the year. If you are a distributor, buying group or fleet who would like to meet in person, we would welcome the conversation, and details on upcoming events will be posted here as they are confirmed.
