The 1058 is probably the 2nd most popular SunCoast converter. This torque converter can be used for both towing and racing. It is 200 RPM higher than factory and works well with almost all mild turbo setups, this even shines with the stock turbocharger. With a stock turbocharger, your vehicle will launch harder and at part throttle, operate like a stock unit while driving normally. This converter will work with both 5 and 6-speed Allisons, alike.
