SPEC Clutch - RB20 RB25 RB26 (Push Type)
Why upgrade your clutch in your Nissan Skyline?
Well, the clutch is the point where your engine and transmission meet. It acts as a torque converter. We all want to make more power but without the proper clutch you won't be able to transmit that power and your clutch will slip. The factory Nissan Skyline RB clutch will not be able to sustain the extra power your motor is demanding to transmit. An upgraded performance clutch will be designed with materials to withstand higher temperatures and clamping force. Know your power goals and use our handy chart below to help decifer which trim will suit your needs.
SPEC clutches and flywheels are manufactured on-site (in the USA) using the most advanced methods under the strictest tolerances. The commitment to making the very finest parts is at the core of what SPEC stands for as a company.
All clutch kits include pilot bushing, aligntment tool, clutch disc, and pressure plate.
| Stage | SKU | Usage | Torque |
| 1 | SN231 | Features an integrally molded carbon kevlar-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally bonded steel backing for strength under high clamp loads and temperatures. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street and many track/off-road applications. |

415 |
| 2+ | SN233H | Features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the 2+ offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rally and drift. |

| 3 | SN233 | Features a carbon semi-metallic 6 puck sprung hub disc that has been the leading puck clutch in drivability, life and torque capacity. This unit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Also available in 3 puck configuration. Great for street, drag, road racing, pulling, rally and drift. |

| 4 | SN234 | This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rally and drift. |
515 |
| 5 | SN235 | Features a full-metallic disc with the highest possible friction co-efficient. Street drivable but not street-friendly. The hub is solid 12-rivet and the assembly is heat treated for strength and durability. Best for extreme street and drag racing. |
