Includes 9 friction; 8 steels and 3 springs. This is a high performance clutch kit. The ”extra plate design” in this kit provides you with more friction disc surface area. This will help prevent slippage; without increasing spring pressure. Comes with Barnett’s exclusive; proprietary Carbon Fiber friction material; tempered steel drive plates and a set of three heavy duty springs. All kits are pre-measured for proper stack height to ensure reliable fit and performance right out of the box.
