These are 5 disk oil cooled clutches that are smaller than an axle clutch they have 6 external adj screws. These are bullet proof, Renee Angle out in Washington had one on a KT100 with I believe just over 40 shows with nothing done but change oil. Tell Kevin what your application is and where you want to engage it at and he will set it up for you. You might have to fine tune it just a little. These hit very hard and are incredibly durable. I'm sure you'll be very happy with one.
