Action Clutch Stage 3 Clutch & Flywheel Kit - 2009-2014 Acura TSX (CU2)
The Action Clutch Stage 3 (1MS) clutch and flywheel kit is built for the 2009-2014 Acura TSX (CU2, K24) and delivers 170% more holding capacity than the factory clutch. That makes it the go-to upgrade for K24 builds pushing past stock power on the street, at the drag strip, or on the drift course, and this version pairs the clutch with a lightened flywheel for a complete drivetrain upgrade in one box.
Read This First: Tuning Required
This kit requires a Hondata FlashPro or equivalent tuning device for proper clutch engagement calibration. The lightened flywheel changes how the engine picks up and holds idle, and the CU2 needs the tune to keep drivability right rather than fighting the factory calibration. Do not install this kit on an untuned vehicle, if FlashPro isn't already on the car, plan for it as part of this job.
Sprung MIBA Ceramic Disc
The kit centers on a sprung MIBA ceramic disc, available in 4-puck or 6-puck, paired with a heavy-duty single-diaphragm pressure plate with reinforced drive straps. The ceramic disc delivers quicker, more positive engagement than a stock organic setup, which is where the extra holding capacity comes from, while the sprung hub keeps it from being brutal on the street. Expect some clutch chatter during break-in, that's completely normal for this disc material and minimizes significantly after the recommended 500-mile break-in.
4-Puck Or 6-Puck
You can run the disc as a 4-puck or a 6-puck. The 4-puck is a bit more forgiving on engagement and easier to modulate, while the 6-puck adds surface area for more holding capacity and a slightly firmer grab. Pick based on your power level and how much low-speed smoothness you're willing to trade.
Included Lightened Flywheel
A lightened flywheel is included to drop rotating mass off the heavy factory piece. That sharpens throttle response and quickens rev pickup, something you'll feel on the first drive, and it's matched to the clutch so both fresh parts go in together while the transmission is already out. A little added noise and vibration at idle is the normal trade for the quicker response.
Built To A Standard That Holds Up
One of the biggest failure points on high-performance clutches is springs ejecting from the disc hub under load. Action Clutch addresses this with patented fully enclosed spring retainers, which keep the torsional springs contained at all times and eliminate that failure mode entirely. Every kit is inspected and signed off by engineers with over 60 years of collective experience before it ships.
Break-In
A proper 500-mile break-in is required. Easy driving lets the friction surface seat and heat cycle evenly, which settles the engagement and the initial chatter and builds the disc's full holding capacity. Avoid riding the clutch during break-in, since repeated slipping works against that.
What You Get
- Sprung MIBA ceramic clutch disc (4-puck or 6-puck)
- Heavy-duty single-diaphragm pressure plate with reinforced drive straps
- Lightened flywheel
- Patented fully enclosed spring retainers
- 170% more holding capacity than stock
Fitment
Direct bolt-on for the 2009-2014 Acura TSX (CU2) with the K24 engine and 6-speed manual transmission. Requires Hondata FlashPro or equivalent tuning. Not compatible with automatic-transmission TSX variants.
Best For
- K24 CU2 TSX builds making power beyond stock, already tuned
- Heavy-duty street use plus occasional drag, road, or drift racing
- Drivers who want maximum holding capacity and quicker response, and will accept a grabbier, chattier clutch
Not Ideal For
- Cars that won't be tuned, FlashPro or equivalent is required
- Daily drivers who want OEM-smooth, chatter-free engagement, look at the Stage 1 or Stage 2
If your CU2 TSX is making real power and the stock clutch can't hold it, the Stage 3 is the one that will while still letting you drive it on the street: a sprung MIBA ceramic disc in 4 or 6 puck, a reinforced heavy-duty pressure plate, a lightened flywheel, and 170% more capacity. Just make sure the car is on FlashPro, break it in over 500 miles, and it'll deliver everywhere it's meant to.
FITMENT
2009-2014 Acura TSX (K24Z3) - Direct bolt-on fitment. No modifications required.
Note: This kit does not fit the V6 TSX. K24 four-cylinder applications only.
