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: RSB520Alignment Tool: CAT120Fitment:Nissan 160B 1976-1980, 1.6 Ltr, L16 J810, 1/76-12/80, New Zealand ModelNissan 180B 1972-1979, 1.8 Ltr, 6 Bolt Crank KPL610, 1/72-12/79, Imported ProductionNissan 180B 1972-1979, 1.8 Ltr, 5 Bolt Crank KPL610, 1/72-12/79, Imported ProductionNissan 180B 1972-1977, 1.8 Ltr, 6 Bolt Crank P610, 1/72-12/77, Imported ProductionNissan 180B 1972-1977, 1.8 Ltr, 5 Bolt Crank P610, 1/72-12/77, Imported ProductionNissan 180B 1972-1977, 1.8 Ltr, 6 Bolt Crank WP610, 1/72-12/77, Imported ProductionNissan 180B 1972-1977, 1.8 Ltr, 5 Bolt Crank WP610, 1/72-12/77, Imported ProductionNissan 200B 1980-1981,, L20 KN810, 1/80-12/81Nissan 200B 1980-1981,, L20 N810, 1/80-12/81Nissan 200B 1980-1981,, L20 NJ810, 1/80-12/81Nissan 200B 1980-1981,, L20 WHL810, 1/80-12/81Nissan 620 Series 1973-1983, 1.5 Ltr GN620, 1/73-12/83Nissan 620 Series 1973-1983, 1.5 Ltr N620, 1/73-12/83Nissan 720 Series 1979-1981, 1.6 Ltr, J16 720, 9/79-11/81Nissan Bluebird 1981-1984, 2.0 Ltr NJ910 Series I, 5/81-5/84Nissan Bluebird 1983-1986, 2.0 Ltr NJ910 Series II, 9/83-1/86Nissan Bluebird 1981-1984, 2.0 Ltr NJW910 Series I, 5/81-5/84Nissan Bluebird 1983-1986, 2.0 Ltr NJW910 Series II, 9/83-1/86Nissan E23 Urvan 1980-1982, 1.6 Ltr VBE23, 1/80-12/82Nissan Navara 1985-1989, 1.6 Ltr, Z16 D21, 8/85-9/89, New Zealand ModelNissan Navara 1989-1997, 1.6 Ltr, NA16 D21, 9/89-12/97, New Zealand ModelNissan Stanza 1978-1983, 1.6 Ltr, L16 KPA10, 1/78-12/83Nissan Stanza 1978-1983, 1.6 Ltr, L16 PA10M, 1/78-12/83Nissan Stanza 1978-1983, 1.6 Ltr, L16 PLA10, 1/78-12/83Nissan Vanette 1986-1990, 2.0 Ltr Diesel, LD20 UC22, 1/86-12/9Nissan 160J 1973-1974, 1.6 Ltr, L16 KP710, 1/73-12/74, New Zealand Model
