- 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
