ACT 1989 Nissan 240SX XT/Race Sprung 6 Pad Clutch Kit
The ACT NX1-XTG6 is a race-level clutch for the 1989 Nissan 240SX with the single-cam KA24E and five-speed. It pairs ACT's Xtreme pressure plate with a six-pad sprung ceramic disc. Buyers usually land on this kit because a turbocharged or heavily built KA24 is slipping a stock or street clutch, or because a drift or track car keeps cooking organic discs on clutch kicks and long sessions.
The Xtreme pressure plate uses a stiffer diaphragm for more clamp load, and the six ceramic pads keep their grip at heat levels that would glaze a full-face organic disc. ACT rates the NX1-XTG6 at 475 ft-lb at the crank, 168 percent over the factory clutch. The disc is 224 mm (8.8 in) with a 1 in input shaft, and the complete kit weighs 14.9 lb.
The spring center is what separates this kit from ACT's rigid race version. The springs soak up torsional shock from hard launches and clutch kicks, which protects the rear diff and axles on an S13. The trade-off is still real: ACT describes moderate to heavy pedal effort, aggressive engagement and OE to mild gear rattle, and recommends it for high-horsepower street or race use. On a near-stock car in traffic it will feel on-off; ACT's street-disc kits for the same car are the better match there.
Do a third-gear pull from about 2,500 rpm with the pedal fully released. If the tach jumps ahead of road speed, the disc is slipping. Before you drop the transmission, check the clutch master and slave for leaks and old fluid, and make sure the pedal returns fully, since a dragging or soft pedal can mimic a bad clutch. Our slipping diagnosis guide covers the road test, and the flare vs. slip guide helps separate real slip from other drivability issues. For budgeting the job, see our manual repair cost guide.
Our listing is for the 1989 Nissan 240SX. ACT's own application list for NX1-XTG6 is wider: the 1989-1990 240SX with the 2.4L KA24E, the 1995-1998 240SX with the 2.4L KA24DE, the 1974-1983 280Z and 280ZX, the 1990 Axxess 2WD, the 1981-1984 Maxima 2.4L and 2.8L diesel, and several 620 and 720 pickups. ACT does not list the 1991-1994 240SX on this kit. Those years take ACT's NX4 series, such as the NX4-HDG6 race kit. SR20DET swaps are a different application entirely. Check your model year and engine, and send us your year and VIN if anything about the car has been changed. More kits are on our rebuild kits page.

No. ACT lists this kit for the 1989-1990 KA24E cars and the 1995-1998 KA24DE cars only. The 1991-1994 240SX uses ACT's NX4 series kits.
Yes. ACT lists the 1995-1998 240SX 2.4L KA24DE on NX1-XTG6 alongside the 1989-1990 KA24E cars.
It can be driven daily, but ACT describes moderate to heavy pedal effort, aggressive engagement and some gear rattle. It is aimed at high-horsepower street or race cars. A stock or lightly modified 240SX will be happier with a street disc kit.
ACT rates NX1-XTG6 at 475 ft-lb measured at the crank, 168 percent over the factory clutch.
The N023X pressure plate, 6224206 sprung six-pad ceramic disc, RB016 release bearing, AT01 alignment tool and PB1012 pilot bushing. A flywheel is not included.
Not always, but the friction face must be flat and clean. Resurface it with the correct step height or replace it, and replace it if it is cracked or heat checked deeply.
