Product Description

The SPEC SN263F is the Stage 3+ clutch kit for the pull-type Nissan Skyline GT-R and GT-T platforms, covering the R32, R33, and R34 generations. It is SPEC's flagship street/strip stage - the highest torque-capacity clutch in the SN26x pull-type lineup that is still recommended for street use. The full-faced carbon semi-metallic disc delivers a combination of high friction coefficient, long wear life, and street-friendly engagement that is unmatched by puck-style or Kevlar disc designs. Rated at 550 ft-lbs of torque at the flywheel, it is well-suited for heavily tuned RB26DETT engines running upgraded turbos, high boost, built motors, or extensive power modifications that exceed the capability of Stage 2 or Stage 3 clutches.

The Stage 3+ uses a double-sprung hub with spring cover reliefs to cushion engagement and minimize drivetrain shock, giving it better daily drivability and pedal feel compared to the rigid-hub Stage 4 and 5 race kits. This makes it the preferred choice for Skyline builds that see regular street use alongside occasional track days or drag strip runs. Flywheel resurfacing is mandatory prior to installation unless a new SPEC flywheel is used, and a 450-mile city/stop-and-go break-in period must be completed before aggressive driving. Fits pull-type GT-R and GT-T applications across R32, R33, and R34 only - for push-type GTS-T/GTS applications, see part number SN233F.
