Competition Clutch 1991-1998 Nissan 240SX Stage 2 - Steelback Brass Plus Clutch Kit
The Competition Clutch 6054-2100 is a Stage 2 clutch kit for the 1991-1998 Nissan 240SX with the KA24DE twin-cam 2.4L and the five-speed manual. It is the kit to look at if your S13 or S14 is slipping on the highway, shudders when you leave a light, or you are adding a header, cams or a light turbo setup and want a clutch that will hold it without turning the car into a chore to drive every day.
The 240SX is a rear-drive car with a hydraulic clutch: the master cylinder at the pedal feeds a slave cylinder on the bellhousing, which moves the release fork and throwout bearing. When the pedal is up, the pressure plate clamps the disc against the flywheel and the disc drives the transmission input shaft. On a high-mileage KA24DE car the disc wears thin, the diaphragm spring loses clamp load, and the original bearing gets noisy, so replacing the set together is the sensible way to do the job once.
The 6054-2100 includes a Competition Clutch performance pressure plate, one full-face disc, a throwout bearing, a pilot bushing and an alignment tool. It does not include a flywheel. The maker's spec table describes the disc as organic, full face, and its product text puts the gain at 40-50 percent more torque capacity with a slightly firmer pedal; the broader Stage 2 family description quotes up to 80 percent and Brass Plus friction on an alloy backing. For a street 240SX the takeaway is the same: a full-face disc that engages smoothly and holds noticeably more than the factory clutch.
Check the hydraulics first. A clutch that will not release, grinds into gear or has a pedal that slowly sinks is more often a master or slave problem than a worn disc, and those parts are cheaper and do not need the transmission pulled. Our guide to a high or low engagement point explains what the pedal height is telling you. To prove slip, use the high-gear load test in our slipping diagnosis guide. If you are also chasing gear noise or a worn synchro, read our 240SX FS5W71C transmission problems page so the transmission gets looked at while it is out.
Our listing covers the 1991-1998 Nissan 240SX, and Competition Clutch lists 6054-2100 for the 1991-98 240SX 2.4L DOHC, which is the KA24DE. That is the later S13 coupe and hatch plus every S14. The 1989-1990 cars with the single-cam KA24E are not on the 6054 application list. Swapped cars, especially SR20DET conversions, use a different clutch. If your 240SX has been swapped or you are not sure which engine and transmission it has, send us the year, VIN and engine code and we will confirm before you order.

Planning more power? The Stage 4 six-puck ceramic kit covers the same KA24DE cars with far more grip and much less street manners.

No. Competition Clutch lists this kit for the 1991-98 240SX 2.4L DOHC (KA24DE). The 1989-90 single-cam KA24E cars are not on its application list.
No. An SR20DET swap uses the SR transmission and a different clutch. Send us your engine and transmission details and we will point you to the right kit.
Pressure plate, one full-face disc, throwout bearing, pilot bushing and an alignment tool. No flywheel is included.
It suits a street or occasional-event KA24DE car with bolt-ons. Repeated clutch kicks on a high-power car are better served by a puck-style disc such as the Stage 4 kit.
At minimum have it resurfaced. Since the transmission is already out, many owners fit a lighter steel flywheel at the same time.
Competition Clutch recommends shifting as often as possible over the first 500 miles so the disc material embeds into the pressure plate and flywheel.
