Clutch Masters 02-06 Acura RSX Base 725 PRO Series Triple Disc Clutch w/Steel Flywheel
A turbocharged K20 RSX making four or five times its factory 160 horsepower will slip a single-disc clutch no matter how aggressive the facing is. Clutch Masters part number 08037P3D7RS is the 725 PRO Series Triple Race clutch with a dedicated steel flywheel for the 2002 through 2006 Acura RSX. It is built for drag and road race K-series cars on big boost, E85 or nitrous, not for a stock or bolt-on daily driver.
The RSX was designed around one organic disc. This kit swaps that for three 7.25 inch rigid ceramic discs with floater plates in one cover, so it has six friction faces instead of two while keeping the diameter small. A small, light clutch pack lets the K20 rev freely between shifts, which is a big part of why multi-disc units are popular on high-rpm Hondas.
In the part number, P3D7R is the Triple Race stage and the trailing S means a steel flywheel is included. Clutch Masters lists the 7.25 inch PRO clutch pack, an alignment tool, the steel flywheel and a release bearing in the box, with an estimated torque capacity of 900 ft-lb. The PRO design uses twelve heat-treated 4140 steel stands where the older FX 725 used six aluminum posts, a change Clutch Masters made because the aluminum posts flexed and wore in high-horsepower use. The steel flywheel is cut from 1045 billet and black-oxide coated. It is a conversion kit and will not work with the Honda flywheel.
We also carry the earlier design as the FX 725 Race three-disc for the RSX, and the 725 PRO twin disc for cars that do not need the third disc.
Log a pull in a high gear and compare engine rpm with wheel speed, or watch for the tach to jump when boost comes in. Then rule out the cheap causes: a clutch master or slave that does not fully release, a misadjusted pedal, or oil from the crank seal or transmission seal at the bellhousing will make any clutch slip. Our slipping diagnosis guide covers separating clutch slip from other driveline faults, and the twin disc vs single disc comparison helps match the clutch to your power.
Our listing is for the 2002 through 2006 Acura RSX. Clutch Masters lists 08037P3D7RS for both RSX versions, the base car with the K20A3 and five-speed and the Type-S six-speed, plus 2002-2015 Civic Si, 2004-2014 TSX, 2003-2012 Accord 2.4, 2006-2011 CSX Type-S and 2013-2015 ILX 2.4 manual. K-swapped chassis, mixed K20 and K24 combinations and aftermarket transmissions need a check before ordering, so send the year, engine code, transmission code and the last 7 of the VIN. More options are in our rebuild kits department.

Clutch Masters lists 08037P3D7RS for both the 2002-2006 RSX base five-speed and the Type-S six-speed.
For most street RSX builds, yes. It is rated around 900 ft-lb with rigid ceramic discs, so it suits high-boost race cars. A twin disc or a single puck clutch fits moderate power better.
No. This is a conversion kit that only works with the Clutch Masters steel flywheel, which is included.
The PRO version uses twelve 4140 steel stands instead of six aluminum posts, so the pressure plate holds up better to heat and abuse at high power.
Honda manual transmission fluid.
Expect rattle at idle and a quick, sharp engagement. That is normal for a rigid multi-disc race clutch.
