Spec Clutch ST662 Stage 2 Kevlar Clutch Kit

The Spec Clutch ST662 Stage 2 Clutch Kit is engineered for drivers who demand more holding power than a stock clutch can provide, without giving up the smooth, predictable engagement needed for daily street use. Ideal for mild to moderately modified naturally aspirated engines as well as power-adder builds, the Stage 2 is also a smart upgrade for stock-power vehicles where exceptional longevity and refined drivability are the priority.

Key Features:

• Pure Kevlar Friction Material: Segmented or full-faced Kevlar disc with steel backing delivers outstanding wear resistance and smooth engagement
• High Clamp Pressure Plate: Increases clamping force over stock for improved torque capacity without sacrificing pedal feel
• High-Torque Sprung Hub Assembly: Double-sprung hub with spring cover reliefs provides flexibility and heat-treated components for long-term strength and durability
• Complete Kit: Includes pressure plate, Kevlar disc assembly, release bearing, and alignment tool for straightforward installation
• Street-Friendly Engagement: Maintains stock-like drivability — no harsh on/off engagement associated with race-only clutches

Ideal Use Cases: Street driving, drag racing, autocross, and pulling applications.

The SPEC Stage 2 builds on the proven Stage 1 platform by offering slightly longer service life and higher torque capacity while retaining the excellent daily drivability SPEC clutches are known for. It strikes the ideal balance between performance and practicality for enthusiasts who push their vehicles on weekends without compromising the daily commute.
