XClutch 99-02 Nissan Silvia S15 2.0L Stage 1 Extra HD Sprung Organic Clutch Kit
The XClutch XKNI24540-1AX is a street clutch kit for the 1999 to 2002 Nissan Silvia S15 with the 2.0L SR20. It suits the imported S15 that has picked up a boost controller, exhaust and tune, where the stock clutch now slips in the upper gears but the car is still driven on the street. The Stage 1X recipe keeps a forgiving organic disc and pairs it with an extra heavy duty pressure plate, so you get more holding power without the on-off engagement of a puck disc.
In the S15, the clutch pedal works a hydraulic master and slave that move the release bearing against the diaphragm of the pressure plate. With the pedal up, the diaphragm clamps the disc between the cover and the flywheel and engine torque passes into the gearbox. XClutch's Stage 1X raises clamping force at the cover while keeping a sprung organic disc in the middle, so engagement stays progressive and the springs in the hub still absorb driveline shock. The maker says it designs each cover's pivot point and diaphragm for positive pedal feel along with the higher clamp.
This is a full package. Per the product data, the kit includes the friction disc, the extra heavy duty diaphragm pressure plate, a flywheel, the release bearing, a pilot bearing, an aligning tool and technical service bulletins where required. Having the flywheel in the box matters on an S15 that may have twenty-plus years and an unknown history behind it.
An imported car often has old hydraulics, so start there. Bleed the system and check that the pedal returns cleanly; a tired master or slave can stop the clutch from clamping fully. Look under the bellhousing for oil from the rear main seal, which contaminates any new disc. Then do a high-gear roll-on from low rpm and watch the tach. Our slipping diagnosis guide covers the full test, and shift flare vs slip helps separate a real slip from other drivetrain issues.
Our listing covers the 1999 through 2002 Nissan Silvia S15 2.0L. The S15 was sold new in Japan and a few other markets, and engine and gearbox swaps are common, so match the car you actually have. The six-speed SR20DET turbo car is the usual fit for this kit. If your S15 has a five-speed, a different engine or an aftermarket flywheel, send us the year and chassis number or VIN before ordering. Shipping weight is about 42 lb because the flywheel is included. More clutch parts are in our rebuild kits category.

It is the Stage 1 organic setup paired with an extra heavy duty pressure plate, giving more clamping force for higher horsepower street cars while keeping organic engagement.
Yes. The kit includes a flywheel along with the disc, pressure plate, release bearing, pilot bearing and aligning tool.
It is listed for the 1999 to 2002 Silvia S15 2.0L. The six-speed turbo car is the usual application, so send us your chassis number or VIN if you have a five-speed or a swap.
Yes. The kit is designed for street use, and the sprung organic disc keeps engagement smooth.
Xtreme Clutch advises driving gently for the first 1,000 km with low rpm engagements so the friction material beds into the flywheel.
It can be. The maker notes a single mass flywheel loses dual-mass dampening and may add some noise and vibration, which is not harmful with the correct disc.
