Competition Clutch 1991-1998 Nissan 240SX Stage 4 - 6 Pad Ceramic Clutch Kit
The Competition Clutch 6054-1620 is a Stage 4 Strip Series clutch kit for the 1991-1998 Nissan 240SX with the 2.4L DOHC KA24DE, covering both the late S13 and the S14 chassis. It is built for the cars that have outgrown every street clutch: turbocharged KA builds, nitrous cars and dedicated drift or drag cars where a slipping disc mid-run ends the session. If your KA24DE is close to stock, this is more clutch than you need.
The 240SX is rear-wheel drive with a longitudinal five-speed, so the clutch sits between the crank-mounted flywheel and the gearbox input shaft, released by a hydraulic slave cylinder pushing the fork. Competition Clutch rates its Stage 4 Strip Series at up to a 250 percent increase in torque capacity over stock. The disc is a six-paddle design with ceramic buttons on a sprung hub; the sprung center softens some of the shock a solid hub would send into the gearbox and differential. Ceramic buttons grab hard and tolerate heat that would glaze an organic disc, which is why they suit clutch kicks and repeated launches. Expect an abrupt engagement point and some chatter when creeping in traffic.
Rule out the hydraulics and oil contamination first. A soft or sinking pedal points to the master or slave cylinder, not the disc, and a leaking rear main seal will make any new clutch slip. With the hydraulics healthy, a top-gear roll-on at partial boost that raises rpm without road speed confirms slip. Our clutch slipping guide covers the test, and if the pedal is the problem, see how to bleed a hydraulic clutch.
Slip has a clear signature that differs from a missed shift or a flare; flare vs slip explains what to watch on the tach.
Competition Clutch lists the 6054-1620 for the 1991-1998 Nissan 240SX 2.4L DOHC, which is the KA24DE. It does not cover the 1989-1990 cars with the single-cam KA24E, and it is not for SR20DET-swapped cars, which take a different clutch and flywheel. Many of these chassis have been swapped and re-swapped, so check that the engine and gearbox are still the factory KA24DE and five-speed, or send us your year and VIN and we will confirm before it ships. Every 240SX clutch and flywheel we carry is in the rebuild kits and clutch category.
Per the Competition Clutch specification table: performance pressure plate, single 6-paddle ceramic disc, throwout bearing, pilot bushing and alignment tool. A flywheel is not included.
Not making big power yet? The 6054 Stage 2 kit is far friendlier on the street.

No. Competition Clutch lists 6054-1620 for 1991-1998 cars with the 2.4L DOHC KA24DE. The 1989-1990 single-cam KA24E cars are a separate application.
No. An SR20DET swap uses the SR engine and gearbox clutch, which is a different kit. This one is for the factory KA24DE and five-speed.
No. The kit includes the pressure plate, six-paddle ceramic disc, throwout bearing, pilot bushing and alignment tool. Resurface your flywheel or buy a new one.
This 1620 version is sprung. Competition Clutch uses the -0620 suffix for its solid-hub six-puck kits.
You can, but engagement is quick and low-speed chatter is normal with a six-puck ceramic disc. For a mildly modified street car, a Stage 2 is the better match.
Competition Clutch recommends shifting as often as possible during the first 500 miles before launches or clutch kicks.
