Spec Nissan RB25/20 Stage 2 Clutch Kit
SPEC's SN232 is the Stage 2 clutch for the push-type Nissan RB20 and RB25 cars: the R31 and R32 Skyline and the R33 GTS. It is the kit RB owners look at when the old clutch flares under boost after a turbo, injector or ECU upgrade, when a Stage 1 has already been outgrown, or when an import has arrived with a tired, high-engaging pedal. SPEC rates it at 439 ft-lb, which leaves real headroom over a stock or mildly built RB without stepping to a puck disc.
Rear-drive RB Skylines bolt the clutch to the back of a long inline six, and the GTS-t style cars release it with a push-type bearing that presses the pressure plate fingers toward the flywheel. SPEC's Stage 2 level uses a Kevlar disc with steel backing. SPEC describes it as keeping excellent drivability while giving longer life and more torque capacity than its organic Stage 1. On the R33 GTS push-type chart the jump is clear:
SPEC lists the SN232 at 19 lb. Kevlar engages progressively like an organic disc, so it suits a car that still sees traffic, while the higher stages trade that smoothness for grip.
On a car this age, check the hydraulics before anything else: old fluid, a weeping slave or a tired master cylinder can feel like slip or poor release. Then load the clutch in a high gear at low rpm with full boost and watch for the tach running ahead of road speed. Our clutch slipping symptoms and fixes page covers the test, and the flare vs. slip guide helps rule out other causes.
Our listing names it as the RB25/RB20 Stage 2. SPEC's application list for SN232 includes:
The key word is push type. A pull-type release, as on the RB26 GT-R, needs a different kit such as our SPEC SN262 Stage 2 for pull-type GT-Rs. Imported cars often have swapped engines and gearboxes, so check your release bearing style and flywheel before ordering, or send us the chassis code and engine and we will check it. More clutch kits are in our rebuild kits collection.
