Our Grand Touring Clutch is the latest development to our clutch lineup. It retains the technology from our Multi-plate Clutches, but with the addition of our unique floating pressure system to provide a smooth and chatter-free driving experience.
The Grand Touring single plate dampened clutches give some forgiveness to the transmission by absorbing drivetrain shock. The result is a quiet and reliable clutch set. This is ideal for those customers looking for a slightly higher capacity clutch for their showcase vehicle to take it to and from their local concourse gatherings.
****For pure motorsports use or dual purpose vehicles, we recommend starting with our STR clutch lineup.****
Flywheel Bolts may require shortening. Please consult installation guide
