Clutch Masters 10306PTD7RS FX725 PRO Twin Disc Clutch Kit with Steel Flywheel

The Clutch Masters FX725 PRO Twin Disc Clutch Kit (10306PTD7RS) is a race-engineered, 7.25-inch (184mm) dual-disc clutch system built for high-horsepower applications demanding maximum clamping force and reliability. This kit includes two ceramic rigid discs and a 4140 billet steel flywheel, making it the "Twin Race" (PTD7R) configuration with steel flywheel — purpose-built for drag racing and track use.

The FX725 PRO represents a ground-up redesign of Clutch Masters' proven FX725 platform, addressing the known limitations of the original unit for extreme race applications. The most significant upgrade is the pressure plate stand configuration: the PRO features 12 heat-treated 4140 steel posts, doubled from the standard aluminum 6-post design, delivering superior structural integrity under high torque, heat, and sustained abuse.

Key Features:

• 7.25" (184mm) twin disc design — optimized for smaller bellhousing applications
• Two ceramic rigid friction discs — maximum heat resistance and grip for race use
• 12-post 4140 heat-treated steel pressure plate stands — vs. standard 6-post aluminum for greater durability
• Billet aluminum cover assembly — Type 3 hard anodized, offering approximately 25% more tensile strength than cast competitors
• QR (Quick Release) Pressure Plate System — three spring-loaded bolts for smooth, even engagement and up to 50% reduction in clutch noise/chatter
• Steel flywheel included — CNC machined from 1045 billet steel, zero balanced, with black oxide coating for rust protection
• SFI Certified — clutch kit and flywheel meet SFI performance standards for motorsport competition
• 100% serviceable — rebuild kits and replacement components available separately
• Made in the USA — designed, manufactured, and assembled in-house by Clutch Masters

The FX725 PRO's minimal rotational mass makes it the ideal choice for focused drag racing and track applications. The included steel flywheel is precision CNC machined from 1045 billet steel, zero balanced, and finished with a black oxide coating for long-lasting rust protection. All components are 100% serviceable, with rebuild kits and individual parts available for economical long-term ownership.
