Spec Clutch SD763F Stage 3 Plus High-Performance Clutch Kit

The Spec Clutch SD763F Stage 3 Plus is the flagship single-disc clutch kit for heavily modified street and race vehicles that demand high torque capacity without sacrificing daily drivability. Engineered as the next step beyond the Stage 3, the Stage 3 Plus replaces the puck-style disc with a full-faced carbon semi-metallic friction surface that delivers smoother, more predictable engagement while maintaining the aggressive torque handling performance-builds require.

The full-face friction design distributes clamping load evenly across the entire disc surface, improving engagement quality, reducing wear, and extending service life under demanding conditions. The double-sprung hub with spring cover reliefs absorbs driveline shock for added flexibility, while heat-treated internal components ensure long-term strength and durability. This stage is widely regarded as the longest-wearing performance friction option in its class, making it equally at home on a daily-driven modified street car or a weekend track build.

Kit Includes:

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

The Stage 3 Plus offers superior modulation in stop-and-go traffic compared to puck-style alternatives, making it Spec Clutch's most versatile single-disc stage — combining race-grade durability with engagement characteristics that remain manageable for everyday driving.
