NAPC Torque Converters

Stall torque ratios, one way clutches, single, multi and triples. North American Powertrain Components is well equipped with an in-house 2000 sq ft. torque converter shop and ready to go inventory.


With our state of the art facility and superior processes we can provide you with a quality finished product that is designed and built for your exact application. From daily drivers to 1500+ horsepower competition vehicles, we are here to serve you with all your torque converter needs.

All remanufactured and repaired torque converters undergo a balancing and hydraulic process to ensure that there are no cracks or leaks. All moving parts must exceed industry standards in precision integrity and performance alongside with its co-applications. We strive for perfection and replace 100% of bearings & clutch linings.
