2400-2800 stall - 12" diameter
1984-'91 GM 700R-4 - 30 spline

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

Made in the U.S.A.


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
