Global Supply Chain
Our global supply management system supports this manufacturing network that qualifies the best suppliers and generates cost-efficiency by leveraging worldwide spending and sourcing in lower-cost countries. Because we supply global platforms, we can streamline development and production.
We are a leader in In-Line Sequenced processes to mesh our operations precisely with customer needs. Additionally, we improve our OE customer service around the world with Just-in-Time (JIT) delivery facilities close to customers’ manufacturing plants.
Our San Antonio emission control JIT facility, for example, is the last stop in a multi-plant continuous production pipeline, which culminates in shipping a full exhaust system every 12 minutes to our customer 500 feet away. Perfecting product flow through operational excellence processes like Kanban, allows us to serve customers’ needs when and where they need it.
