ST1 Upgrade Disc - High torque sprung disc assembly lined with a heavy duty steelback organic friction material. By riveting "steel to steel" M-Pact's advanced steel back friction material provides additional clamping force and superior burst strength. The reinforced steel backing allows for better heat dissipation delivering extended wear and quick recovery. The M-Pact ST1 disc is assembled using precision engineered components designed for slight increased horse power applications. Each disc is assembled with a HD retainer stamping and increased hardness hub to ensure maximum strength and reliability. Six inner and six outer heavy duty torsional dampening springs work with this assembly to ensure a smoother engagement.

Tips & Tools For The Job

• Wear a Dust Mask to protect against hazardous clutch dust. You can also spray the clutch with water prior to removal to reduce the amount of airborne dust during disassembly.
• Use a Flywheel Turner to hold the flywheel in place while removing and reinstalling the pressure plate bolts.
• Apply Blue Threadlocker to flywheel bolts prior to installation to prevent backing out due to the high vibrations flywheels are subject to.
• Use the provided lubricant to lightly lubricate the splines of the input shaft. Over lubricating the input shaft risks lubricant transfer to the clutch friction disc and can cause clutch slippage.
• Be sure to install the new clutch friction disc in the correct direction. The disc will have a "Flywheel Side" label on one side.
