Spec clutch kits include a new pressure plate, clutch disc, release bearing, alignment tool and even a new pilot bearing. Stage 1: High clamp pressure plate, steel-backed woven organic disk, bearing(s), and installation alignment tool. Excellent high performance replacement clutch for naturally aspirated (non-supercharged) engines. Stage 2: Performance pressure plate, segmented chatter free Kevlar disc with H.D. sprung hub, plus bearings & install tool. Higher grip clutch recommended for power adder cars (supercharged, nitrous oxide, etc.) and stroker engines using regular street tires. Stage 3: High-clamp pressure plate, 3-piece disc* with carbon or ceramic material, bearing(s) and install tool. ULTIMATE HIGH HORSEPOWER STREET/STRIP CLUTCH. Sharp but smooth engagement with moderate pedal effort. Recommended for higher boost supercharged or nitrous cars, blower+stroker combinations, racing with slicks or high torque cars with drag radials. *The Stage 3 three-piece disc has a heavy duty sprung hub, as traditionally used on street clutches. Stage 4 & 5 clutches with a solid hub and no Marcel spring between the two sides of the disc are available by special order. Note: solid hubs are not recommended for street transmissions due to the severe shock-load that can be transmitted to the driveline. Call for more information. Clutches listed are for the Ford Mustang. We will be glad to special order clutches for any application. *These parts are over-sized and may incur additional freight* Spec 10.5" Stage 1 Clutch Kit Fits: 86-95 5.0 96-98 4.6L Cobra 96 thru Jan. 01 4.6L GT 351 Conversions 1995 Cobra R Rated Torque Capacity 410 lb-ft.
