_Steel Back Heavy Duty Street System, 70% over stock holding capacity_ The FX100 System uses the Power Plus I Pressure Plate with the Steel Back organic disc. This clutch is engineered for heavy-duty street use. It is specifically designed for extended wear and additional clamping force for the enthusiast who has added an exhaust system, an intake system, up to 50hp NO2 upgrade, or other non-forced induction external bolt-ons. As with most Clutch Masters clutches, the FX100 incorporates the Hi-Leverage pressure plate design and the steel back disc. It features only slightly increased pedal pressure (over stock components), longer life than stock, and normal clutch feel during engagement and disengagement for a very smooth operation *Features* * High performance street system * Holding capacity 70% over stock * Heavy-Duty reinforced pressure plate * Hi-Leverage pressure ring design * Sprung hub/cushioned disc * Steel backed organic friction material *Includes* * Pressure Plate * Clutch Disc * Throw-out Bearing (when applicable) * Pilot Bearing or Bushing (when applicable) * Alignment Tool PartNumber : cm07051-HR00-H Description : FX100 Clutch Kit; High Rev Pressure Plate; Sprung Hub Steel-Backed Organic Lined Disc; Hydraulic Slave Cylinder Included 2012-2013 Ford Mustang Boss 302 V8.4951cc Drivetrain::Clutch Kits - Single 2011-2017 Ford Mustang GT V8.4951cc Drivetrain::Clutch Kits - Single 2015 Ford Mustang GT 50 Years Limited Edition V8.4951cc Drivetrain::Clutch Kits - Single 2015-2017 Ford Mustang GT Premium V8.4951cc Drivetrain::Clutch Kits - Single
