TKO Extreme- Rated at 950ft lbs of torque
This includes upgraded components that move the ft lb rating from 600 to 950 to handle Butler Performance high torque/high HP engines. Also includes Cryo traetment. The Cryo Treatment is a process of taking the transmission apart and freezing the gears and inner components and warming them up and refreezing them as this is done is makes the internals hardens which with a few other upgrades we do makes the transmission capable of holding 950 hp/tq to the wheels unlike the stock transmission which will only hold 600 hp/tq.
