Spec Clutch SN353H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SN353H Stage 2 Plus Clutch Kit is engineered for modified engines that have outgrown the torque capacity of the standard Stage 2 clutch. Bridging the gap between the Stage 2 and Stage 3 performance levels, the Stage 2 Plus delivers the familiar, street-friendly engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — making it an ideal upgrade for enthusiasts running bolt-on or more aggressive engine modifications.

At the heart of this kit is a multi-friction composite disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar® on the other. This hybrid friction pairing delivers excellent wear characteristics, strong torque transfer, and the smooth, progressive engagement expected from a daily-drivable performance clutch.

Key Features:

• High-clamp pressure plate for increased clamping force on modified engines
• Full-faced multi-friction disc with carbon semi-metallic / Kevlar® hybrid material
• Double-sprung hub with spring cover reliefs for flexibility and vibration damping
• Heat-treated components for long-term strength and durability
• Includes high-torque sprung hub and disc assembly
• Release bearing and alignment tool kit included

Ideal Driving Applications: Street, Drag Racing, Road Racing, Rally, Autocross, and Pulling

Designed, hand-built, and tested in the U.S.A., the SPEC SN353H is backed by SPEC's industry-leading torque guarantee — if your clutch fails below its rated torque capacity under proper installation and break-in procedures, SPEC will replace it free of charge. A proper 500-mile break-in period with primarily stop-and-go driving is required before full-throttle use.
