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 TR3B was designed with Naturally Aspirated engines in mind. This is the lightest triple disc clutch/flywheel assembly you'll find for most applications. The clutch discs are 204mm in size and is good up to about 700lbs ft for NA/supercharged motors. The aluminum cover allows for higher clamping force (increased capacity) and will handle the hard abuse often found at the track.
