What Advanced Clutch Technology does

Advanced Clutch Technology (ACT) is a privately held US manufacturer of high-performance drivetrain components, founded in 1994 and headquartered in Lancaster, California. The company designs, engineers, and manufactures performance clutches, flywheels, pressure plates, and clutch discs for the automotive aftermarket, with most products certified to SFI Spec 1.1 standards. Its core product families include ACT Single Disc Clutch Kits, Mod-Twin Multi-Disc Clutch Kits (featuring a proprietary Adjustable Positive Lift Floater system), XACT one-piece chrome-moly forged flywheels, four-stage heat-treated pressure plates, and both organic street and ceramic race friction discs, supported by bearings, engine swap kits, and rebuild components. The company also offers a smaller adjacent line of motorcycle gear sets and shift forks for off-road applications.

ACT manufactures in-house at its Lancaster facility with production test equipment for clamp load checking, release travel verification, computer dynamic spin balance (to .25 oz-in precision), and diaphragm cycling. Engineering is conducted in-house using CAD, FEA simulation, and CAM tools, with new diaphragms and pressure plate faces designed for each specific application rather than using off-the-shelf components. The catalog spans 2,442+ SKUs, with torque capacity increases ranging from 20% to 400% over stock depending on the configuration. A 1-year limited warranty is offered, which is materially longer than the 90-120 day industry standard.

The business model is hardware sales through three primary channels: a direct-to-consumer e-commerce site at advancedclutch.com with vehicle-specific product search, a global distributor and dealer network accessed through a dealer locator, and direct phone-based sales for technical support and custom applications. Products are sold as one-time unit purchases at price points ranging from small accessories under $20 to over $2,400 for triple-disc extreme race kits. Customer segments are primarily performance automotive enthusiasts, race teams, and motorcycle riders, with no disclosed enterprise or B2B anchor accounts. The company is founder/family owned, with no venture capital, private equity, or institutional funding evident in available materials.
