Spec Clutch SF842 Stage 2 Kevlar Clutch Kit

The SPEC SF842 Stage 2 Clutch Kit is engineered for drivers who demand more than a stock clutch can deliver. Ideal for mild to moderately modified naturally aspirated engines and power-adder applications, the Stage 2 also performs exceptionally well at stock power levels where long service life and confident daily drivability are priorities.

Key Features:

• Full-face or segmented pure Kevlar® friction disc with steel backing for outstanding wear resistance and torque capacity
• High-clamp performance pressure plate for improved clamping force over OEM
• Double-sprung hub with spring cover reliefs for smooth engagement flexibility and heat-treated components for long-term strength and durability
• 8.875-inch disc diameter with 23-spline input shaft interface (1.031 in. diameter)
• Bearing and alignment tool kit included for straightforward installation
• Flywheel not included — sold as clutch kit only

The Stage 2 delivers a meaningful step up in torque capacity and service life compared to the Stage 1, while retaining the smooth, stock-like pedal feel and daily drivability that SPEC's Kevlar friction material is known for. Suitable driving applications include street, drag racing, pulling, and autocross.
