Spec Clutch SA303H-3 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SA303H-3 Stage 2 Plus Clutch Kit is engineered to bridge the gap between the Stage 2 and Stage 3 performance levels, delivering the smooth drivability and refined engagement feel of the Stage 2 with a 15–20% higher torque capacity. This makes it an ideal upgrade for enthusiasts who demand more holding power without sacrificing everyday street manners.

At the heart of this kit is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction pairing optimizes both heat resistance and longevity, striking a balance between aggressive performance and long service life. The double-sprung hub incorporates spring cover reliefs for added flexibility, while heat-treated internal components ensure lasting strength and durability under high-load conditions.

Key Features:

• High-clamp pressure plate for increased clamping force and improved torque transfer
• Hybrid Kevlar and carbon-graphite friction disc in a full-faced configuration for superior heat management and engagement quality
• 15–20% higher torque capacity compared to the Stage 2, without sacrificing street drivability
• Double-sprung hub with spring cover reliefs for flexibility and reduced drivetrain shock
• Heat-treated hub components for enhanced strength and long-term durability

The Spec SA303H-3 Stage 2 Plus is a versatile high-performance clutch solution for modified street and competition vehicles that have outgrown a Stage 2 but prefer a more manageable engagement than a full Stage 3 delivers.
