The TR Clutch series line-up was designed for vehicles which have substantial increases in engine power. The billet aluminum cover provides a more direct clutch pedal feel, but still maintains ease of engagement due to the unique leverage mechanism of the diaphragm spring to reduce overall pedal effort.

The TR2B was designed with common tuner engines in mind. The clutch discs are 204mm in size and are good up to about 500lbs ft for NA motors. This type of clutch will give great engine response possible while also handle a fair amount of torque output. The aluminum cover allows for higher clamping force (increased capacity) and will handle the hard abuse often found at the track.
