SADEV know-how
Since 1974, we have been contributing to motorsport performance by developing, manufacturing and assembling high technology transmission systems for drivers, vehicle manufacturers and teams across the globe. We are driven by a constant desire to innovate, combining our mechanical expertise, our people, and our industrial capabilities.
Innovation & Development
As a leader in the design and manufacture of gearboxes and transmission components, innovation is a cornerstone of our business, enabling us to develop high-performance products for private customers, racing teams, chassis manufacturers and automobile manufacturers.
Today, our extensive product portfolio serves a wide range of motorsport disciplines, from regional competition to world championship level, including Rallying, Circuit Racing, Single-seaters, Endurance, Rallycross, Off-Road, Hill Climb, Drift, Drag Racing and Autocross, as well as all types of powertrains, including internal combustion, electric, hybrid and hydrogen technologies.
At SADEV, innovation is built upon:
- Continuous product development and technology watch for products, processes and materials
- An in-house training academy and experienced employees,
- Co-engineering and independent product development,
- Reverse engineering, analysis of existing products,
- 80+ machines, continuously upgraded through ongoing investment,
- Intellectual property development through patent filings,
- Investment in research and innovation.
This quest of performance enables us to deliver custom solutions to meet the specific needs of motorsport. The demanding requirements of programmes such as the Dakar Rally, WEC, WRC and Formula E directly influence our engineering decisions, placing performance and reliability at the heart of our development strategy.
In 2025, SADEV Industries was established through the acquisition of several companies. The group now brings together specialists in high precision machining and transmission components serving highly demanding industries such as nuclear energy, defence, petrochemicals and aerospace. This organisation helps to create synergies, to share expertise, to strengthen technical capabilities and quality standards, while providing increased production capacity for the benefit of our customers.


A fully integrated manufacturing process
At our production site in Saint-Prouant, we carry out every stage of the manufacturing process in-house, enabling us to provide our customers with consistent quality, greater agility and a single interlocutor. We maintain full control over key processes that make the difference, from heat treatment and surface treatment to gear grinding or electron beam welding.
This expertise is enhanced by a complete traceability throughout our fully integrated manufacturing process:

Our manufacturing capabilities and machinery
More than 250 employees work at our main production site. Some are dedicated to manufacturing operations, day and night, while others support our business through a wide range of support and engineering functions. This organisation enables us to maintain responsive customer service, operational agility and consistently high quality standards across all our projects.
