Using this South Bend Clutch Extreme Stage 4 Clutch Kit is straightforward. First, make sure your car is suitable according to the fitment details. If your vehicle has HP modifications beyond stage 3, this kit is for you. When installing, ensure that you use a single - mass steel SFI - approved flywheel for safety. The clutch engagement can be a bit abrupt, so take some time to get used to it when you start driving. Your hydraulic system may need enhancing for proper clutch separation, so check it before you hit the road. As for maintenance, keep an eye on the torque ratings which are calculated at the time of ordering. Regularly inspect the pressure plate and discs for any signs of wear. Since the friction materials can be Sintered Iron or Graphite Impregnated Ceramic, they offer good thermal resistance, but don't push the clutch to its limits constantly to ensure a longer lifespan.
