Clutch Masters 02-06 Acura RSX 2.0L Type-S 6 Sp (High Rev) / 02-06 Honda Civic SI 2.0L& 6 Sp (High R
Clutch Masters 08037-HRC6 is the FX400 sprung 6-puck ceramic clutch kit for the six-speed K20: the 2002-2006 Acura RSX Type-S, the 2006-2011 Honda Civic Si and the 2006-2011 Acura CSX Type-S. It is built for a turbo or supercharged K20, or a hard-driven track car, where a Kevlar or organic disc keeps slipping under full load but you still need hub springs to keep the drivetrain from banging on the street.
The K20 six-speed uses a hydraulic clutch with a slave cylinder on the transmission case that pushes the release fork. The FX400 pairs the Clutch Masters Power Plus I hi-leverage heavy-duty pressure plate with a sprung ceramic button disc in a six-puck paddle layout. Clutch Masters rates it at a 170 percent increase in holding capacity and calls it a race and street system. The sprung hub gives moderate dampening, which is what separates it from the rigid FX500 kit for the same car.
The six-puck disc has solid rivets and no Marcel cushion, so it engages quickly and may chatter slightly in first gear and reverse. Clutch Masters says ceramic discs are not meant for stock or near-stock cars, where they can actually shorten clutch life. If you want the same cover with a smoother engagement, the FX300 Kevlar kit 08037-HRTZ is the street-friendly choice.
Run a full-throttle pull in fourth gear from low rpm. If the tach climbs faster than the speedometer, the disc is slipping. Before blaming the clutch, check the clutch reservoir, look for fluid at the slave cylinder and confirm the pedal returns fully. Oil weeping from the bellhousing seam means a crank or input seal needs attention or it will soak the new disc. Our slipping diagnosis guide covers the test, and the rebuild vs replace guide helps if the gearbox also has worn synchros.
Clutch Masters lists 08037-HRC6 for the 2002-2006 Acura RSX 2.0L Type-S six-speed, the 2006-2011 Honda Civic Si 2.0L six-speed and the 2006-2011 Acura CSX Type-S six-speed. Our listing title reads 02-06 Civic Si; the maker's list covers the 2006-2011 eighth-generation Civic Si, not the 2002-2005 hatchback. The five-speed base RSX is not on the list, and the 2012-up Civic Si moved to the K24, which takes the 08240 kits. No flywheel is included. Match the part number on your old parts, or send us the year and VIN before ordering.
Need even more holding for a race car? The FX500 race kit 08037-HRB6 uses the Power Plus II cover with a rigid disc. Our manual repair cost guide helps you plan the labor.
