The patented Centerforce Dual-Friction disc system distributes pressure plate clamping force evenly over a 360-degree friction-facing on one side of the clutch disc, while the opposing side uses a segmented friction-facing to concentrate clamping pressure and maximize clutch holding-capacity. This combination of dual configured friction-facings, coupled with our performance pressure plate, creates the ultimate clutch system that is engineered for smooth drivability, maximum longevity and awesome grip!
