GM Performance Torque Converters

Built in Dearborn for GM power.

Dearborn Precision Performance Parts designs and builds high-performance stall converters specifically for GM transmissions — including 4L60E, 4L65E, 4L70E, 4L80E, 4L85, 6L80, 8L90 and more. Every converter is engineered and assembled in the birthplace of the automobile with one goal: reliable power transfer under real-world abuse.

Whether you’re building a street car, weekend warrior, or serious track machine, our GM converters deliver consistent flash stall, strong lockup where applicable, and the durability to handle the torque these engines make. We thoroughly TIG-weld the impeller and turbine assemblies, build-in heavy-duty sprags, HD clutches use high-energy clutch materials, and CNC-machined components so the converter holds up when you put your foot down.

What you’ll find in this collection:

  • Street and strip stall ranges (3000–4000+ RPM options)
  • Single-clutch and multi-clutch (billet forged / triple clutch) designs
  • Converters built for both daily driving manners and high-horsepower applications
  • Precision balanced and tested units ready for installation

All of our GM torque converters are made in the 313 with the same no-compromise approach we bring to every product. Browse the options below, match the stall and clutch style to your setup, and get a converter built to dominate Detroit streets and the drag strip.
