Spec Clutch SA873H-3 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SA873H-3 Stage 2 Plus Clutch Kit is engineered to bridge the gap between the Stage 2 and Stage 3 clutch systems. It delivers the smooth, street-friendly engagement feel of the Stage 2 while adding 15–20% more torque capacity, making it an ideal upgrade for enthusiasts who demand more from their drivetrain without sacrificing daily drivability.

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 gives the Stage 2+ its distinctive balance of grip, heat resistance, and wear durability. The hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components provide long-term strength under demanding conditions.

All Spec clutch kits and flywheels are SFI approved, ensuring they meet stringent safety and performance standards for both street and competition use.
