Spec Clutch SB153F Stage 3 Plus Clutch Kit

The SPEC SB153F Stage 3 PLUS Clutch Kit is engineered for heavily modified street and race applications that demand torque capacity beyond what the standard Stage 3 can handle. Designed for high-output engines running forced induction, aggressive camshafts, or other significant power modifications, the Stage 3 PLUS delivers exceptional holding power while retaining better daily drivability and pedal manageability compared to a full Stage 3 setup.

Built around a high-clamp pressure plate and a full-faced carbon metallic friction disc, this kit is engineered for superior heat resistance, aggressive torque transfer, and improved wear longevity over conventional stage clutches. The high-torque sprung hub and disc assembly helps absorb driveline shock and smooth engagement, making it more street-friendly than an unsprung racing disc.

Kit Includes:

• High-clamp pressure plate
• Full-faced carbon metallic friction disc with high-torque sprung hub assembly
• Pilot bearing
• Alignment tool

Recommended Applications:

• Heavily modified street vehicles
• Drag racing
• Drifting
• Road racing
• Pulling / high-torque events

The Stage 3 PLUS bridges the gap between aggressive track use and street drivability — ideal for builds that have outgrown a Stage 3 but require a more manageable pedal feel than a full racing clutch setup.
