Spec Clutch SK161 Stage Performance Clutch Kit - 1 with Organic Disc

The Spec Clutch SK161 Stage 1 Clutch Kit is a high-performance upgrade engineered for drivers who demand reliable power transfer on the street and at the track. Built around an integrally molded carbon Kevlar-based organic friction lining, this clutch delivers smooth, predictable engagement with excellent wear life — outperforming standard OEM replacements in both durability and torque capacity.

The friction disc features an integrally bonded steel backing plate that reinforces the assembly under high clamp loads and elevated operating temperatures, maintaining consistent clamping force across a wide range of driving conditions. The hub uses a double-sprung design with spring cover reliefs, reducing driveline shock and vibration while heat-treated internal components add long-term strength and fatigue resistance.

Kit Features:

• High-clamp performance pressure plate for increased torque holding capacity over stock
• Steel-backed, multi-compound woven organic disc for smooth engagement and extended service life
• High-torque double-sprung hub and disc assembly for vibration dampening and driveline protection
• Includes release bearing and alignment tool for straightforward installation

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Autocross

The Spec Stage 1 is the ideal entry-level performance clutch for naturally aspirated and mildly modified vehicles that see regular street use alongside occasional track or off-road duty. Spec clutches are designed, hand-built, and tested in the U.S.A., and the Stage 1 lineup is recommended for street and strip applications where smooth driveability and long service life are the top priorities.
