Designed and manufactured to replace the clutch system installed as Original Equipment, a Heavy Duty replacement clutch kit features a torque capacity increase due to a higher clamp load (typically 20% increase compared with original equipment (OE). Each component has been thoroughly tested and developed for a specific application. This range provides a Quality Assured replacement part that will meet or exceed the requirements of the original unit. After 15 years of experience in developing and manufacturing clutch kits for Aftermarket use, PHC is the trusted source for a complete range of Clutch Kits suited to your vehicle. PRODUCT NOTES: PHC Heavy Duty Clutch Kits are manufactured with a (typical) 20% increase in clamp load, resulting in an equivalent increase in torque capacity. Increasing clamp load by more than 20% can put the vehicles hydraulic system under stress, significantly reduce clutch system life and result in very high clutch pedal actuation effort. Therefore if additional torque capacity is required, please consider a 4Terrain or Mantic clutch kit to suit your application. Beware of imitation products with clamp loads greater than 20% over OE specification. Heavy Duty clutch kits with a SSCC/SSC/SC suffix, feature upgrade cerametallic clutch plates. SSCC clutch plates feature dual sided cerametallic friction material, designed to further increase torque capacity, with a moderate reduction in pedal feel and more sudden engagement. SSC clutch plates feature dual sided cerametallic friction material with no segment cushioning, designed to further increase torque capacity, with a significant reduction in pedal feel and aggressive sudden engagement. SC clutch plates feature dual sided cerametallic friction material with no segment cushioning and a non-sprung hub, designed to further increase torque capacity, but offering very little pedal feel and ultra aggressive sudden engagement - not suitable for street use.This kit includes : Heavy duty cover assembly with 20% (typical) increase in torque capacity / clamp load, Clutch plate, Release bearing Features and SpecificationsHeavy Duty Clutch Kit Suits OE FlywheelTypical 20% Increase in Torque CapacityDual Mass Flywheel: Not IncludedFlywheel Step: Torque Capacity: Solid Flywheel: Not IncludedConcentric Slave Cylinder: Not IncludedSpigot: RSB590Alignment Tool: CAT186Fitment:Buick 1964-1967, 300ci 1/64-12/67Chevrolet Bel Air 1972-1973, 250ci, 6 Cyl 1/72-12/73Chevrolet Camaro 1969-1973, 307ci, V8 1/69-12/73Chevrolet Camaro 1967-1969, 327ci, V8 3 Speed, 1/67-12/69Chevrolet Camaro 1976-1977, 305ci, V8 1/76-12/77Chevrolet Chevelle 1964-1967, 283ci, V8 4 Speed, 1/64-12/67Chevrolet Chevelle 1968-1973, 307ci, V8 3 Speed, 1/68-12/73Chevrolet Chevelle 1964-1968, 327ci, V8 1/64-12/68Chevrolet Chevelle 1964-1967, 283ci, V8 3 Speed, 1/64-12/67Chevrolet El Camino 1964-1969, 230ci, 6 Cyl 1/64-12/69Chevrolet El Camino 1978-1978, 3.3 Ltr, V6 1/78-12/78Chevrolet El Camino 1968-1970, 250ci, 6 Cyl 1/68-12/7Chevrolet El Camino 1976-1978, 305ci, V8 1/76-12/78Chevrolet El Camino 1964-1965, 194ci, 6 Cyl 1/64-12/65Chevrolet Impala 1972-1973, 250ci, 6 Cyl 1/72-12/73Chevrolet Malibu 1964-1967, 327ci, V8 1/64-12/67Chevrolet Malibu 1976-1978, 305ci, V8 1/76-12/78Chevrolet Malibu 1964-1967, 283ci, V8 4 Speed, 1/64-12/67Chevrolet Malibu 1978-1978, 3.3 Ltr, V6 1/78-12/78Chevrolet Malibu 1973-1973, 307ci, V8 3 Speed, 1/73-12/73Chevrolet Malibu 1964-1967, 283ci, V8 3 Speed, 1/64-12/67Chevrolet Monte Carlo 1978-1978, 3.3 Ltr, V6 1/78-12/78Chevrolet Monte Carlo 1976-1978, 305ci, V8 1/76-12/78Chevrolet Monte Carlo 1978-1978, 3.8 Ltr, V6 1/78-12/78Oldsmobile Cutlass 1978-1978, 305ci, V8 1/78-12/78Oldsmobile Cutlass 1978-1978, 231ci, V6 1/78-12/78Oldsmobile Cutlass 1965-1967, 330ci, V8 1/65-12/67Oldsmobile Cutlass 1971-1973, 350ci, V8 3 Speed, 1/71-12/73, 2 BarrelOldsmobile Delmont 88 1967-1967, 330ci, V8 1/67-12/67Oldsmobile Delta 88 1967-1967, 330ci, V8 1/67-12/67Oldsmobile Delta 88 1971-1973, 350ci, V8 3 Speed, 1/71-12/73, 2 BarrelOldsmobile F85 1965-1967, 330ci, V8 1/65-12/67Oldsmobile F85 1971-1972, 350ci, V8 3 Speed, 1/71-12/72, 2 BarrelOldsmobile Omega 1977-1978, 305ci, V8 1/77-12/78Oldsmobile Omega 1978-1978, 231ci, V6 1/78-12/78Oldsmobile Omega 1973-1973, 350ci, V8 3 Speed, 1/73-12/73, 2 BarrelOldsmobile Vista Cruiser 1971-1973, 350ci, V8 3 Speed, 1/71-12/73, 2 BarrelOldsmobile Vista Cruiser 1965-1967, 330ci, V8 1/65-12/67Pontiac Bonneville 1970-1970, 350ci, V8 3 Speed, 1/70-12/7Pontiac Bonneville 1961-1964, 389ci, V8 1/61-12/64, 2 BarrelPontiac Catalina 1970-1973, 350ci, V8 3 Speed, 1/70-12/73Pontiac Catalina 1961-1964, 389ci, V8 1/61-12/64, 2 BarrelPontiac Executive 1970-1970, 350ci, V8 3 Speed, 1/70-12/7Pontiac Firebird 1977-1978, 231ci, V6 1/77-12/78Pontiac Firebird 1977-1978, 305ci, V8 1/77-12/78Pontiac Firebird 1968-1977, 350ci, V8 3 Speed, 1/68-12/77Pontiac Grand Am 1973-1973, 350ci, V8 3 Speed, 1/73-12/73Pontiac Grand Am 1978-1978, 305ci, V8 1/78-12/78Pontiac Grand Am 1975-1975, 350ci, V8 3 Speed, 1/75-12/75Pontiac Grand Prix 1962-1964, 389ci, V8 1/62-12/64, 4 BarrelPontiac Grand Prix 1962-1964, 389ci, V8 1/62-12/64, 2 BarrelPontiac Lemans 1978-1978, 231ci, V6 1/78-12/78Pontiac Lemans 1971-1971, 350ci, V8 3 Speed, 1/71-12/71Pontiac Phoenix 1978-1978, 231ci, V6 1/78-12/78Pontiac Phoenix 1978-1978, 305ci, V8 1/78-12/78Pontiac Ventura 1977-1977, 305ci, V8 1/77-12/77Pontiac Ventura 1972-1977, 350ci, V8 3 Speed, 1/72-12/77Pontiac Ventura 1961-1966, 389ci, V8 1/61-12/66, 2 Barrel
