Clutch Masters Clutch Kit

Why Clutch Masters Clutch Kits Stand Apart

Clutch Masters has spent over four decades solving one of the most stubborn problems in performance drivetrain engineering: how to dramatically increase a clutch's holding and clamping capacity without burdening the driver with a brutally heavy pedal. The answer is their proprietary Hi-Leverage™ technology — a re-engineered leverage and fulcrum point on the pressure plate that clutch kit buyers simply won't find replicated anywhere else in the aftermarket.

By re-engineering the leverage or fulcrum point on the pressure plate through the Hi-Leverage™ technique, Clutch Masters has increased the clamping power of their single-disc offerings without changing pedal pressure — by as much as 400 percent for racing vehicles. This matters especially because increased pedal pressure raises the chances of damaging the crank thrust bearing, which can lead to crank-walk, and puts additional strain on clutch linkages, throwout bearings, and hydraulic systems, causing them to fail prematurely.

The FX Series: A Kit for Every Stage of Performance

Clutch Masters organizes their clutch kit lineup into a clearly tiered FX Series, so drivers can match the right kit to their actual power level and intended use:

• FX100 (Stage 1): The FX100 uses a Power Plus I Heavy-Duty Pressure Plate with a steel-backed organic friction disc, engineered for street vehicles with minor bolt-ons such as exhaust or intake systems — featuring only slightly increased pedal pressure over factory with longer service life and a smooth engagement feel.
• FX300 (Stage 3): The FX300 offers a 110% holding capacity increase over stock with a segmented Kevlar disc for exceptional holding power and long life — the ideal choice for aggressive drivers who still desire smooth engagement.
• FX400 (Stage 4): The FX400 utilizes a 6-puck ceramic sprung disc with a bulletproof hub assembly, designed for cars with significant power upgrades, with hard and quick engagement using the Power Plus I Pressure Plate paired with an extremely durable sprung ceramic disc.
• FX725 & FX850 Twin Disc: The FX725 and FX850 PRO Series multi-disc clutch kits are built for one purpose — handling serious power without compromise, redesigned from the ground up to deliver unmatched strength, improved reliability, and race-proven performance.

The QR System and Twin Disc Innovation

What separates Clutch Masters twin disc kits from the competition goes beyond raw clamping force. Unique to Clutch Masters is the QR System, or Quick Release Pressure Plate, which incorporates three spring-loaded bolts allowing the pressure plate to engage and disengage evenly and smoothly. The QR System reduces internal clutch noise and chatter by up to 50%, and was developed specifically to provide quiet, smooth operation for the street user while still delivering the performance a multi-disc race clutch demands.

For extreme-duty applications, the FX850 Strapped bridges the gap between a single disc clutch that is easy to drive on the street and the original FX850 Twin Disc — utilizing drive straps to isolate the pressure plate and mid-plate between the two discs to virtually eliminate chatter and allow for a much smoother engagement.

Friction Materials and USA Manufacturing

Having specialized in performance clutches for decades, Clutch Masters has researched and tested hundreds of different friction materials — from organic to ceramic, sintered iron and everything in between — using only the best materials for each intended application, resulting in a line of clutches that provide ultimate performance in virtually any severe environment. Importantly, as a premier manufacturer of aftermarket clutch kits, flywheels, and hydraulics, everything Clutch Masters makes is built in the USA.

All stages come as a complete kit including disc, pressure plate, throwout bearing, and pilot bearing (when applicable) — everything needed for a clean, confidence-inspiring installation.
