Clutch Masters 02-06 Acura RSX 2.0L Type-S 6 Sp (High Rev) 725 Race Three Disc w/Steel FW
Turbo K20 RSX owners who keep frying single disc clutches at the drag strip end up shopping for a multi-disc unit. Clutch Masters 08037-3D7R-S is the FX725 Race three disc clutch packaged with a billet steel flywheel for the 2002-2006 Acura RSX Type-S six-speed. It is a dedicated drag racing clutch: three small 7.25 inch (184 mm) discs stacked inside a billet cover, built to hold power that would slip any street clutch in a K-series bell housing.
The K-series bell housing limits how big a clutch can be, so instead of a larger disc Clutch Masters stacks three 7.25 inch discs. Three friction pairs give far more holding capacity than a single factory-style disc while keeping rotating mass very low, which lets the engine rev freely between shifts. The Race stage uses rigid ceramic discs with no springs in the hub, so engagement is abrupt and you will hear and feel it more than a sprung street clutch. The cover is machined from billet aluminum and hard anodized; Clutch Masters says it flexes only about .003 inch compared with up to .030 inch for a cast or stamped cover, which keeps the release point consistent pass after pass. Their QR quick release system uses three spring-loaded bolts to separate the plates evenly and reduce internal chatter. The included flywheel is machined from a 1045 billet steel core and black oxide coated, a better choice than aluminum if the car still sees some street miles.
Bleed the clutch hydraulics and check the master and slave before blaming the clutch, because a K-series pedal that does not fully release feels a lot like a worn disc. Look for oil on the bottom of the bell housing from a leaking rear main seal. Then do a rolling test in fourth gear at low RPM and give it full throttle; if RPM rises faster than road speed, the clutch is slipping. Our transmission slipping diagnosis guide explains how to separate clutch slip from other problems, and the rebuild vs replace guide helps if gearbox damage shows up when it comes apart.
This listing is for the 2002-2006 Acura RSX Type-S with the 2.0L K20 and six-speed manual. Clutch Masters lists the same 08037-3D7R-S for the 2002-2006 RSX base 5-speed, the 2002-2005 Civic Si 5-speed, 2006-2011 Civic Si 6-speed, 2012-2015 Civic Si 2.4L, 2004-2014 TSX, 2003-2012 Accord 2.4L, 2013-2015 ILX 2.4L and 2006-2011 CSX Type-S. Swapped engines and transmissions are common on these cars, so confirm you have a K-series engine and transmission before ordering, or send us the year and VIN. A street-friendlier option is the FX725 Race/Street twin disc 08037-TD7S-S, which pairs a ceramic disc with an organic disc.
Clean the crank flange, check the pilot area and use new flywheel bolts torqued to the factory spec. Keep the disc stack in the order supplied and center it with a clutch alignment tool before torquing the cover evenly in a crisscross pattern. While the transmission is out, replace a tired slave cylinder and line; our RSX clutch master, slave and braided line kit covers both. Refill the clutch hydraulics with fresh brake fluid of the type Honda specifies and refill the transmission with Honda MTF. Clutch Masters asks for at least 500 miles of normal stop-and-go driving for break-in, with no full-throttle shifts or compression braking. Expect more noise and a harsher engagement than stock; that is normal for a rigid race multi-disc and why Clutch Masters calls it only suitable for occasional street use.

Yes. Clutch Masters lists 08037-3D7R-S for both the 2002-2006 RSX Type-S six-speed and the 2002-2006 RSX base five-speed, plus several K-series Civic Si, TSX, Accord, ILX and CSX applications.
It is built for drag racing. Clutch Masters says the FX725 can handle occasional street driving, but the rigid ceramic discs engage abruptly and make more noise than a street clutch. For a daily driver, the Race/Street twin disc is the better fit.
Yes. This kit includes a billet steel flywheel machined from a 1045 core with a black oxide finish, matched to the 7.25 inch triple disc assembly.
The clutch hydraulics use the same brake fluid Honda specifies for the factory system, and the K-series manual transmission takes Honda MTF. Use fresh fluid and bleed the slave after the install.
Clutch Masters calls for a minimum of 500 miles of normal stop-and-go driving with no full-throttle shifting or compression braking before you race it.
