The 1058 is probably the 2nd most popular converter we sell at SunCoast.

This torque converter can be used for both towing and racing. It is 200-300 RPM higher than factory and works well with almost all mild turbo setups, this even shines with the stock charger.

With a stock charger, 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.
