Spec 92-02 Honda Prelude Stage 2+ Clutch Kit
The SPEC SH143H is a Stage 2+ clutch kit for the fourth- and fifth-generation Honda Prelude, catalogued by SPEC for 1992 through 2002. It is aimed at the Prelude owner whose clutch now slips at the top of second or third, or who has added an intake, header, tune or cams to the H22 and wants a clutch with real margin that still drives like a street car. SPEC rates the kit at 365 ft-lb of torque capacity, far more than any naturally aspirated Prelude engine makes, which leaves headroom for aggressive driving and later upgrades.
The Prelude's five-speed manual transaxle is driven through a single-disc clutch. When you let the pedal up, the pressure plate clamps the disc between itself and the flywheel; pressing the pedal moves the hydraulic release fork and bearing to unload the diaphragm so the gearbox can shift. A clutch slips once engine torque exceeds what the clamp load and the friction material can hold, which is why a tired factory clutch often gives up first in the high-rpm VTEC range of an H22.
SPEC builds its clutches in stages. Its Stage 2 uses a steel-backed Kevlar disc for drivability and long life. Stage 2+, which this kit is, uses a multi-friction disc that SPEC says keeps the drivability of Stage 2 while adding 15 to 20 percent more torque capacity. Paired with a high-clamp pressure plate and a sprung hub, that gives a firm but streetable engagement rather than the on-off grab of a puck-style race disc. SPEC lists the kit's weight at 14 lb.
Check the hydraulics first. Look at the clutch master reservoir level, then for fluid at the slave cylinder and its line; a soft pedal or one that does not return points at the hydraulic side, which a new clutch kit will not fix. Next, do a load test in fourth gear from about 2,500 rpm at full throttle. If the tach rises faster than the car accelerates, the disc is slipping. Our clutch slipping guide covers the test step by step, and shift flare vs. slip explains what genuine slip feels like. If the problem is chatter rather than slip, read our clutch chatter guide before buying, because engine mounts and the flywheel can cause it.
Our listing and SPEC's catalog name the Honda Prelude for 1992 through 2002. The SPEC SH143H page also lists the 1997-1999 Acura CL and the 1990-2002 Accord four-cylinder, while some catalogs narrow the Accord to 1990-1993 and the CL to 1997 only. Because those lists disagree, Accord and CL owners in particular should compare the old disc's diameter and spline count with the new one before installation, and swapped cars should be matched to the engine and gearbox actually fitted, not the badge. The Prelude in these years used several 2.2L and 2.3L four-cylinders, including the H22 and H23. Send us the year and VIN with your order if you want the fit double-checked. More clutch and flywheel parts are in our rebuild kits and clutch section.

SPEC lists the 1992-2002 Honda Prelude. Check the engine and gearbox actually installed in your car, especially if it has been swapped, and compare the old disc before installing.
SPEC's own page adds the 1997-1999 Acura CL and the 1990-2002 Accord four-cylinder, but other catalogs list a narrower range. Accord and CL owners should send us the year and VIN or match the disc diameter and spline count first.
SPEC rates SH143H at 365 ft-lb. SPEC describes Stage 2+ as keeping Stage 2 drivability with 15 to 20 percent more torque capacity.
Stage 2+ uses a full-faced multi-friction disc on a sprung hub, not a puck-style race disc, so it is meant to stay usable on the street. Expect a firmer pedal than stock.
A flywheel is not in the kit. Resurface the factory flywheel at minimum, or replace it if it is cracked, heat-checked or worn past spec. Lightweight steel flywheels for the Prelude are listed on this page.
