Thanks for your interest in purchasing the TAPP clutch. Here are a couple of important bullet points to know:
1) The KWI TAPP clutch is a very robust clutch that will handle a ton of horsepower
2) It is easy to tune and very adjustable
3) Clutch could be used in other scenarios, however, we recommend it in drag racing and/or applications over 350 wheel horsepower
As with many UTV parts/systems, there are a couple of items that TAPP has encountered that your clutch can possibly be affected by, if they arise these items may be warrantied directly by TAPP.
1) Moveable sheave bushing may bind on bearing causing sticky operation
2) Bearing to shaft tolerance could cause the bearing to stop spinning and make car hard to shift
3) Clutch sheaves may experience accelerated wear when used with certain belt compounds
