Spec Clutch SC153F Stage 3 Plus Clutch Kit

The Spec Clutch SC153F Stage 3 Plus Clutch Kit is SPEC's flagship single-disc performance stage, engineered for heavily modified street and race engines that demand high torque capacity without sacrificing everyday drivability. The Stage 3+ steps up from the standard Stage 3 by replacing the puck-style disc with a full-faced carbon semi-metallic friction surface, delivering smoother, more predictable engagement along with superior wear characteristics.

Unlike puck-style clutches, the full-face disc design distributes clamping pressure evenly across the entire friction surface, improving engagement quality, reducing chatter, and extending service life under demanding conditions. The result is a clutch that bridges the gap between aggressive street performance and race-level torque capacity — manageable enough for daily commuting, yet capable of handling the rigors of drag racing, road racing, drifting, and pulling.

Kit Includes:

• High-clamp performance pressure plate
• Full-faced carbon semi-metallic friction disc
• High-torque sprung hub and disc assembly
• Release bearing and installation tool kit

Key Features:

• Full-faced carbon semi-metallic disc — offers unparalleled friction coefficient, service life, and drivability in a single package
• Double-sprung hub with spring cover reliefs for flexibility and vibration damping
• Heat-treated hub components for long-term strength and durability
• High-clamp pressure plate for secure power transfer under high torque loads
• SFI approved — meets stringent safety certification standards
• Made in the U.S.A.
