Clutch Masters 94-01 Acura Integra 1.8L VTEC FX500 6-Puck Clutch Kit
Clutch Masters 08913-HRB6 is the FX500 6-puck kit for the B-series Honda drivetrain: the 1994-2001 Acura Integra 1.8L, the 1994-1997 Civic del Sol 1.6L DOHC and the 1999-2001 Civic Si. It is the kit for a drag car or a high-boost turbo B18 or B16 that has already burned through Kevlar and sprung ceramic discs. It is not a daily-driver clutch, and Clutch Masters labels it race only.
The B-series cars use a hydraulic clutch: the master cylinder feeds a slave cylinder on the bellhousing, which pushes the fork and release bearing into the diaphragm fingers. The FX500 replaces the factory pressure plate with the Clutch Masters Power Plus II cover, which uses two stacked heat-treated diaphragms, heavy-duty straps and a hi-leverage design for very high clamp load. The disc is a solid-hub six-puck ceramic button disc with no Marcel cushion. Clutch Masters rates the FX500 at 200 to 400 percent more holding capacity than stock, and states it is SFI certified to spec 1.2 for sanctioned drag and road racing.
The trade-off is drivability. With no hub springs and no Marcel, the disc engages and releases almost instantly, pedal effort is heavy, and it chatters. Clutch Masters says ceramic discs are never recommended for stock or near-stock cars. If your car sees regular street miles, the sprung 6-puck FX400 kit 08913-HRC6 is the closer fit.
Make sure the problem is really the clutch. A slipping clutch lets engine speed jump with no matching gain in road speed during a full-throttle pull in a high gear. Check the clutch reservoir level and look for wetness at the slave cylinder, because a sticking or leaking hydraulic circuit can hold the bearing against the fingers and fake a slip. Oil on the bellhousing seam points to a crank seal that will contaminate any new disc. Grinding into gear with a good disc is usually hydraulics or worn synchros. Our slipping diagnosis guide walks through the road test.
Clutch Masters lists 08913-HRB6 for the 1994-2001 Acura Integra 1.8L, VTEC and non-VTEC, excluding the Type R, plus the 1994-1997 Honda Civic 1.6L DOHC (del Sol) and the 1999-2001 Civic Si 1.6L DOHC. Our listing names the Integra only, but the part number is the same. The kit has no flywheel. B-series swaps into other chassis, aftermarket transmissions and Type R gearboxes can differ, so match the part number on your old parts or send us your year and VIN before ordering.
Compare it against the Competition Clutch Stage 4 rigid ceramic kit if you want another race option, and see our manual transmission repair cost guide to budget the labor.

Clutch Masters labels the FX500 race only. The solid-hub ceramic disc engages instantly and chatters, and pedal effort is heavy. For a street car, look at the sprung FX400 6-puck (08913-HRC6) or the FX300.
No. Clutch Masters lists 08913-HRB6 for the 1994-2001 Integra 1.8L VTEC and non-VTEC models, excluding the Type R.
Yes. The same part number is listed for the 1999-2001 Civic Si 1.6L DOHC and the 1994-1997 Civic 1.6L DOHC used in the del Sol.
No. Resurface your flywheel if it is within spec, or replace it. A lightweight flywheel will add to the harsh engagement.
Bleed the clutch hydraulics with DOT 3 brake fluid and refill the gearbox with Honda MTF.
Clutch Masters states the FX500 is SFI certified to spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA.
