X-Clutch XKHN21506-1A Stage Sprung Organic Clutch Kit with Chromoly Flywheel - 1

The X-Clutch XKHN21506-1A is a Stage 1 performance clutch kit designed for the Honda Fit 1.5L, featuring a single sprung organic friction disc and a lightweight chromoly flywheel. This complete kit delivers a meaningful upgrade over the factory clutch while maintaining the smooth, daily-drivable pedal feel that street drivers demand.

X-Clutch — also known as Xtreme Clutch — is the US arm of Australian Clutch Services, a company with over 25 years of experience engineering high-performance clutch systems for street and track applications. Their kits leverage the latest pressure plate design and friction material composition to deliver an optimal balance of performance and driveability.

Key Features:

• Stage 1 Sprung Organic Disc: Provides excellent vibration dampening and smooth engagement, making it ideal for performance street use with minor bolt-on modifications such as an intake, exhaust, or tune
• Chromoly Steel Flywheel Included: Lightweight 4140 chromoly flywheel reduces rotating mass for improved engine response while delivering exceptional strength
• Optimized Pressure Plate Design: Engineered pivot point and diaphragm geometry ensures positive pedal feel and increased clamping force over stock
• Sprung Hub Damper: Absorbs peak shock loading and driveline vibration for a more refined street driving experience
• 212mm Clutch Disc Diameter with a 22mm spline diameter and 20-spline count
• Complete Kit: Includes pressure plate, sprung organic friction disc, chromoly flywheel, release bearing, pilot bearing, and alignment tool

The -1A designation in the part number indicates this is an entry-level performance upgrade — suited for vehicles with stock to mildly modified power outputs. Kits in this class typically represent a 15–20% increase in torque capacity over the OEM clutch. For higher-output applications requiring greater heat resistance, X-Clutch offers the XKHN21506-1B (Stage 2 Sprung Ceramic) variant.
