Spec Clutch SZ365 Stage 5 Clutch Kit - Full-Metallic Sintered Iron Disc

The SPEC SZ365 Stage 5 Clutch Kit is SPEC's top-tier single-disc performance clutch solution, purpose-built for extremely modified drag race engines, pulling applications, and powertrains that demand a slipper-clutch or progressive torque-induced engagement. This is a race-focused assembly engineered without compromise for high-output builds that push the limits of what a single-disc clutch can handle.

Key Features:

• Full-metallic sintered iron disc — delivers the highest possible friction coefficient for maximum torque transfer under extreme conditions
• High-clamp pressure plate — adjustability available on select applications for fine-tuned engagement
• Solid 12-rivet hub — rigid iron disc assembly designed for strength and durability under racing loads
• Heat-treated disc assembly — provides superior strength, temperature resistance, and resistance to slip under punishing conditions
• Progressive engagement characteristics — relative to the Stage 4, the full-face disc surface area allows for a more controlled engagement at launch
• Bearing and tool kit included — everything needed for installation is provided in the kit

Intended Use: Drag racing and pulling. Not recommended for daily street driving due to harsh engagement characteristics. Due to the highly application-specific nature of the Stage 5, this kit is best ordered after consulting with a SPEC technical representative to ensure proper configuration for your vehicle and power level.

Important Note: The SPEC Stage 5 is street-drivable but not street-friendly. It is intended for race use or extreme high-output builds operating at the limits of single-disc clutch performance. Custom configuration is strongly recommended for optimal results.
