XClutch 93-98 Nissan Skyline GT-R 2.6L R33 Stage 1 Sprung Organic Clutch Kit
XClutch XKNI25003-1A is a Stage 1 single-plate clutch with a sprung organic disc for the R33 Nissan Skyline GT-R and its 2.6L RB26DETT twin-turbo straight six. It is the kit for an imported R33 GT-R that is mostly stock or lightly modified, where the original clutch is worn out, slipping on boost, or chattering on takeoff, and the owner wants more clamp than stock without giving up easy street manners.
XClutch's Stage 1 range is its street upgrade: a single organic disc with a stronger pressure plate than the factory unit. XClutch says the sprung organic kits offer the best dampening and the highest driveability in its lineup, which matters on an all-wheel-drive GT-R where every bit of driveline shock is shared between the gearbox, transfer and both axles. The sprung hub cushions takeoff and gear changes, and the organic facing grabs progressively instead of on-off like a ceramic button disc.
The R33 GT-R uses a pull-type clutch release, and XClutch publishes a dedicated pull-type technical bulletin with this kit. In a pull-type system the release bearing clips into a locating collar on the pressure plate and the fork pulls it away from the flywheel to free the disc, so correct assembly of that bearing is the difference between a clutch that releases and one that does not.
Run a slip test in fourth gear from low rpm at full throttle and watch whether the tach outruns road speed. On a 25-plus-year-old import, check the clutch fluid, master and slave cylinder and the hose first; a soft or sinking pedal is a hydraulic fault, not a disc. Look for oil at the bellhousing seam from the rear main or gearbox input seal, since oil on the disc causes slip and chatter on any clutch. Our slipping diagnosis guide covers how to separate these, and the rebuild versus replace guide helps if the gearbox itself is noisy or popping out of gear.
Our listing is titled for the 1993 to 1998 R33 Skyline GT-R 2.6L. The R33 chassis began in 1993, but the GT-R version with the RB26DETT arrived in 1995, so in practice this covers 1995 to 1998 GT-R cars. XClutch's own catalog also tags XKNI25003 kits to the R32 GT-R RB26DETT and to the 2001 Nissan Pathfinder SE 3.5L. It is not for the R33 GTS-t with the RB25DET, which uses a different clutch. If your car has had a gearbox swap or an aftermarket flywheel, match the flywheel and release style before ordering, or send us the chassis code and model so we can check. Stepping up in power later? The SPEC Stage 2 Skyline kit and the Clutch Masters FX350 Skyline kit hold more torque. More options are in our rebuild kits category.

No. This kit is for the GT-R with the RB26DETT. The GTS-t uses the RB25DET and a different clutch, so it needs a different part number.
It is meant for stock and lightly modified street cars. XClutch positions Stage 1 for light modifications and street use; for big boost, track use or heavy launches, step up to a Stage 2 or a twin-plate kit.
At minimum the flywheel must be resurfaced. XClutch's warranty requires the flywheel to be machined or replaced when the clutch is installed.
On a pull-type clutch the release bearing must go on the gearbox input sleeve and fork first, not onto the pressure plate. XClutch's pull-type bulletin warns that fitting it to the cover beforehand makes assembly impossible.
Use DOT 3 or better and never silicone DOT 5. Drive about 1,000 km gently at low rpm before launches or hard shifts.
