X-Clutch XKNI23009-1C Stage 2 Single Cushioned Ceramic Clutch Kit

The X-Clutch XKNI23009-1C is a Stage 2 Single Cushioned Ceramic Clutch Kit engineered for the Nissan Silvia and 180SX S13 platform with the 1.8L engine. Designed to deliver significantly higher heat capacity and torque holding capability than a standard organic clutch, this kit is the ideal upgrade for performance street and light track applications.

The cushioned ceramic friction disc features a sprung hub with additional dampening built between the friction surfaces, resulting in smoother engagement and improved pedal modulation compared to the standard sprung ceramic (1B) disc. This makes the XKNI23009-1C particularly well-suited to high-performance street driving where both power handling and daily driveability are important.

Key Features:

• Stage 2 Cushioned Ceramic Disc — Higher heat capacity and torque capacity over the organic Stage 1 range
• Sprung Hub with Cushioned Design — Provides superior pedal modulation and smoother engagement vs. standard sprung ceramic
• High-Performance Pressure Plate — Engineered for increased clamping force and positive pedal feel
• 1-Inch Input Shaft Diameter — Correct fitment for the S13 1.8L drivetrain
• Includes Alignment Tool, Release Bearing, and Pilot Bushing — Complete kit for straightforward installation
