Spec Clutch SF463H Stage 2+ Performance Clutch Kit

The Spec Clutch SF463H Stage 2+ Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle, while still preserving the street-friendly engagement characteristics that make daily driving comfortable. Rated at 669 ft-lbs of torque and designed for the 10-spline input shaft, this kit bridges the gap between the Stage 2 and Stage 3 in SPEC's performance clutch lineup.

Key Features:

• Multi-friction composite disc in a full-faced configuration — carbon semi-metallic on one side and Kevlar on the other for superior grip and wear resistance
• 15–20% higher torque capacity than the standard Stage 2, without sacrificing drivability or engagement quality
• High-clamp pressure plate for increased clamping force to handle added power
• Double-sprung hub with spring cover relieves for flexibility and heat-treated components for long-term strength and durability
• 10-spline input shaft compatibility for proper fitment
• Includes bearing and alignment tool kit for complete installation

Ideal Driving Applications:

• Street / Daily Driving
• Drag Racing
• Road Racing
• Rally
• Autocross
• Pulling

The SF463H Stage 2+ delivers a meaningful performance upgrade for modified Mustang GT engines running power adders or aggressive naturally aspirated builds, all while maintaining the pedal feel and smooth engagement that SPEC's Stage 2 platform is known for.
