C4-C5-C6 Performance Converters

C4 / C5 / C6 Performance Torque Converters
Classic Ford strength, built in Dearborn.

Dearborn Precision Performance Parts builds high-performance stall converters for the legendary C4, C5, and C6 transmissions. These are the workhorses of classic Mustangs, Fairlanes, Torinos, and countless other Ford performance builds — and they deserve a converter that can keep up.

Every unit is engineered and assembled in Dearborn with thorough TIG-welding on the impeller and turbine, heavy-duty sprags, USA-made bearings, and CNC-machined components. The result is consistent flash stall, strong power transfer, and the durability to handle real torque without giving up.

What you’ll find here:

  • Street and strip stall ranges (3000–4000+ RPM options)
  • Anti-balloon designs with welded construction and bearings
  • Converters built for both street manners and high-horsepower applications
  • Precision balanced and tested units ready for installation

Whether you’re running a classic Mustang, a Fox-body project, or any other C4/C5/C6-backed build, these converters are made in the 313 to dominate Detroit streets and fly at Milan Dragway.
