ACT 2002 Acura RSX HD/Perf Street Sprung Clutch Kit
The ACT AR1-HDSS is the clutch most K20 owners actually want: more holding power than the factory unit with an organic disc that still drives smoothly in traffic. It fits the 2002-2006 Acura RSX base and Type-S, the 2004-2008 Acura TSX 6-speed and the 2002-2011 Honda Civic Si. If your RSX has an intake, header and tune and the original clutch has started to slip at the top of third, or the old disc is simply worn out at high mileage, this kit is the sensible replacement.
The RSX uses a single dry disc clamped between the flywheel and pressure plate, with a hydraulic slave pushing the release bearing. ACT's Heavy Duty pressure plate (H024) uses a revised diaphragm to raise clamp load and reduce deflection. The disc (3000108) is ACT's Performance Street sprung disc: a full organic face with high copper content for heat transfer, steel-backed lining for burst strength and a spring-damped hub. ACT rates the kit at 255 ft-lb at the crank, 35 percent over the factory clutch, and describes the feel as light to moderate pedal effort with smooth, positive engagement. ACT's own FAQ says to expect pedal effort to rise 15 to 40 percent with a Heavy Duty plate, depending on the car.
Compared with the 6-pad race version of this kit, the HDSS gives up some torque capacity in exchange for normal street manners. That is the right trade for a naturally aspirated or lightly modified K20. Boosted cars belong in the HDG6 or Xtreme kits.
Do a load test: fifth gear around 2,500 rpm, then full throttle. If engine speed jumps ahead of road speed, the disc is slipping. Separate that from a release problem: if the clutch grinds into gear or the pedal feels soft, inspect the master, slave and line first. A wet bellhousing seam means oil on the disc, which has to be fixed at the same time. Our slipping diagnosis guide walks through the road test, and shift flare vs. slip helps if you are not sure what you are feeling.
Our listing title says 2002 Acura RSX. ACT's application chart for AR1-HDSS lists the 2002-2006 RSX 2.0L (K20A2, K20A3, K20Z1) in both base and Type-S trim, the 2004-2008 TSX 2.4L (K24A2) 6-speed and the 2002-2011 Civic Si 2.0L. The disc is 214 mm (8.4 in) with a 1.03125 in input shaft. Swapped K-series engines in other chassis are outside ACT's list, and some cars carry aftermarket flywheels that change the setup. Match the disc size and spline on your current clutch, or send us your year and VIN and we will check it. Every RSX clutch, flywheel and hydraulic part is in the rebuild kits and clutch category.
There is no flywheel in the kit. ACT lists the kit weight at 11.0 lb.

ACT lists both RSX base and Type-S from 2002 to 2006 on the AR1-HDSS chart. Check that your disc and flywheel match the 214 mm setup, or send us your VIN and we will confirm.
ACT rates it at 255 ft-lb at the crank, 35 percent over the factory clutch. That covers bolt-on and tuned naturally aspirated K20 cars. Boosted builds should look at AR1-HDG6 or the Xtreme kits.
Slightly. ACT says its Heavy Duty plates typically raise pedal effort 15 to 40 percent depending on the car, and describes the feel as light to moderate.
No. You get the pressure plate, disc, release bearing, pilot bushing and alignment tool. Resurface the old flywheel or install a new one.
ACT recommends 300 to 500 miles of gentle engagement, like everyday city driving, before racing or hard launches, and warns against overheating it during that time.
