Clutch Masters 02-06 Acura RSX Base 725 PRO Series Twin Disc Clutch w/Steel Flywheel
A boosted K20 in a 2002-2006 Acura RSX will eventually find the limit of any single-disc clutch, usually as rpm flare on the 2-3 shift or in fourth at full boost. Clutch Masters part number 08037PTD7RS is the 725 PRO Series Twin Race clutch with a matched billet steel flywheel. Clutch Masters estimates its torque capacity at 700 ft-lb, enough for a big-turbo street and strip RSX while staying lighter and more manageable than a triple disc.
The K-series bell housing does not leave room for a larger single disc, so Clutch Masters doubles the friction surface instead. Two 7.25 inch rigid ceramic discs with a floater plate between them give four friction faces inside one compact cover. The small diameter keeps rotating mass down, which helps a K20 that likes to rev drop rpm quickly between shifts.
In the part number, PTD7R means the Twin Race stage and the trailing S means a steel flywheel is included. The PRO version replaces the six aluminum posts of the older FX 725 with twelve heat-treated 4140 steel stands. Clutch Masters made that change because the aluminum posts flexed and wore under high-horsepower abuse. The steel flywheel is machined from 1045 billet and black-oxide coated, which suits a car that still sees street miles. This is a conversion kit; it will not bolt to the Honda flywheel. Clutch Masters lists the box contents as the 7.25 inch PRO clutch pack, an alignment tool, the steel flywheel and a release bearing, and says the kits are SFI certified and made in the USA.
Make a full-throttle pull in fourth from low rpm and watch whether engine speed rises faster than road speed. Before blaming the disc, bleed the hydraulics and check that the master and slave fully release, and look under the bell housing for oil from the rear main seal. Our slipping diagnosis guide covers separating clutch slip from other driveline problems, and the twin disc vs single disc comparison helps decide whether you need two discs or three.
Our listing covers the 2002-2006 Acura RSX. Clutch Masters lists 08037PTD7RS for both RSX versions, the base 2.0L five-speed and the Type-S 2.0L six-speed. The same part also covers the 2002-2005 Civic Si five-speed, 2006-2011 Civic Si 2.0L and 2012-2015 Civic Si 2.4L six-speeds, 2004-2014 TSX, 2003-2012 Accord 2.4L, 2006-2011 CSX Type-S and 2013-2015 ILX 2.4L six-speed. K-swaps and mixed engine and transmission combinations are common on these cars, so confirm your engine and transmission codes or send us the year and last 7 of the VIN. Need more holding power? The 725 PRO triple disc for the RSX is rated at 900 ft-lb. For a more forgiving street engagement, the 725 Race/Street twin disc pairs a ceramic disc with an organic one. More options are in our rebuild kits department.

Expect some rattle at idle and a quick, firm engagement. That is normal for a rigid ceramic multi-disc clutch.
Refill the transmission with Honda manual transmission fluid, bleed the hydraulics, and drive at least 500 miles of normal stop-and-go before any hard launches.
