The FX100 Heavy-Duty Clutch Kit by Clutch Masters is engineered to deliver 70% increased holding capacity, making it an ideal choice for street-driven vehicles with moderate performance upgrades. Featuring a steel-backed organic friction material disc, this clutch provides reliable engagement and extended wear life, even when subjected to added bolt-on modifications such as exhaust or intake systems, nitrous oxide setups up to 50 horsepower, or other external enhancements. Designed with smooth operation in mind, it offers only slightly increased pedal pressure over stock while maintaining a normal clutch feel during engagement and disengagement, ensuring driver confidence and vehicle reliability.
This kit includes a heavy-duty organic friction disc, OEM or better release bearing, pilot bearing if applicable, Marcel spring wafer, and an alignment tool for precise installation. The clutch assembly is suitable for both light performance upgrades and heavy-duty applications, making it an optimal choice for fleet, commercial, and enthusiast vehicles that demand durability and consistent performance. The use of high-quality components ensures long-lasting operation and minimal maintenance, essential for fleet reliability and high-mileage use.
Installation should be performed by experienced technicians familiar with clutch system servicing. Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of checking the mechanical linkage, ensuring precise pushrod alignment, and verifying a straight, unbinding travel path during installation. These steps are critical to prevent premature wear, internal cup binding, or system failure, especially on vehicles with modified powertrains or specific application constraints.
