Freudenberg-NOK Sealing Technologies Expanding Aftermarket Portfolio

Freudenberg-NOK Sealing Technologies to Acquire Alto Products Corp.

November 4, 2025 – Freudenberg-NOK Sealing Technologies (FNST), together with its aftermarket division Corteco, has acquired Alto Products Corp., the world’s oldest and largest independently owned manufacturer of clutch plates and automatic transmission parts. This acquisition strengthens Freudenberg’s position in the North American and global aftermarket, expanding their product and service offerings for customers worldwide.

Alto Products Corp. operates a 270,000-square-foot manufacturing facility in Atmore, Alabama, with additional sales and distribution locations in Mexico, the Netherlands, and China. The family-owned company employs approximately 240 people, with 230 based in the United States. Alto is renowned for its friction plates, steel reaction plates, and comprehensive kits for automatic transmissions, serving automotive, heavy-duty, and marine segments.

“With the acquisition of Alto Products Corp., we are not only expanding our product portfolio but also reinforcing our commitment to delivering comprehensive, high-quality solutions to our customers. Alto’s legacy, technical expertise, and strong brand presence in the aftermarket align perfectly with our strategic vision,” said Dr. Christian Dickopf, Senior Vice President of Freudenberg-NOK Sealing Technologies’ Corteco Division.

The acquisition enables FNST to offer complete transmission rebuild solutions by integrating Alto’s friction and steel plates into new product offerings for the market. This unlocks growth in heavy-duty and recreational vehicle segments, enhances vertical integration, improves risk management, and strengthens supply chain resilience through Alto’s U.S.-centric manufacturing. It also expands FNST’s reach into international markets by leveraging Alto’s established presence in Latin America and Asia, while creating opportunities to consolidate product lines and operations across FNST’s global footprint.

Judy Love, North American Vice President of the Corteco division, said, “This partnership strengthens our ability to deliver comprehensive solutions to customers across North America and globally. We are excited to welcome Alto’s skilled team into the Freudenberg organization.”

The acquisition marks a strategic step forward for Freudenberg-NOK Sealing Technologies. It reinforces the company’s commitment to long-term growth, operational excellence, and customer-focused innovation in the transmission aftermarket sector.
