Q & A

What's in the Box

Races are won or lost at the starting line, so make sure you come out ahead with a High Performance Torque Converter. Whether you are looking for a street, strip, racing, or just plain heavy duty converter, these units will deliver lasting performance in your GM TH350 or TH400. With features like welded internals, oversized bearings, and hardened hubs, you can rest assured that these torque converters are of the highest quality possible. Made in the U.S.A.

  • For Turbo 350 or Turbo 400 transmission applications
  • 2200-2600 stall - 12" diameter 
  • 1968-'81 GM - 10-3/4" bolt circle

All stall ranges will vary depending on the engine setup, vehicle weight, and gear ratios.

Note: These converters will work with TH400 transmissions only if a dual bolt pattern flywheel is used.

Notes

  1. All advertised stall ranges will vary depending on your engine's setup and the weight of your vehicle. If your car is heavier than the recommendation, the stall speed will be higher. If the car is lighter, stall speed will be at a lower RPM.
  • Hardened Hub
    • Increased durability through the allowance of tighter tolerances and clean fit with transmission seals
  • Welded Impeller
    • Stronger pump fins to maintain stall speed over the life of the converter
  • Heavy-Duty Stators
    • Heat treated fins, sprag and race designed to efficiently handle high power loads
    • Stator fins are formed, not cut - cut stators can cause severe slippage
    • Rapidly dissipates heat - more power to the wheels
  • Welded Turbines
    • Pre-stressed before welding - more rigid construction
    • Heat treated splines
  • Aluminum Spacers
    • Incorporates aircraft quality aluminum spacers which handle higher loads than fiber spacers found in standard converters
  • Oversized Bearings
    • High strength stamped bearings absorb shock and extreme abuse better than standard waffle bearings
  • High Tech Welds
    • Positive-charged, military grade MIG welds for complete fusion of the metal
