PRODUCT DETAILS
Action Clutch 7.25" Triple Disc Race Clutch Kit (ACR-2226-3D) - 2006-2011 Civic Si (K20Z3)
This is a serious race clutch, the kind that goes in 7-second drag cars. Action Clutch's 7.25" triple disc kit holds 1200 ft-lb of torque through three sintered metallic race discs, in a lightweight billet aluminum cover, with the matched flywheel included as part of the assembly. It's built for 8th gen Si builds making the kind of power that overwhelms anything less, a dedicated race component, not a street clutch, with the requirements that come with that.
⚠ RACE USE ONLY — PEDAL STOP REQUIRED
This is a race-only clutch, not for street or daily driving. A pedal stop is required, running a multi-disc clutch without one can overextend the release system and cause premature wear or damage. Do not use without a pedal stop, and expect the aggressive on/off engagement of an unsprung race clutch.
1200 ft-lb Through Three Sintered Discs
The holding capacity is the headline, and the triple disc design is how it gets there.
The kit uses three sintered metallic race discs, formulated in the USA, which together hold 1200 ft-lb of torque. That's genuine big-power territory, the reason this is the chosen clutch for many 7-second drag cars, where a twin disc or single disc would slip.
Spreading the clamping across three discs is how you get that enormous holding power without a brutal pedal, the load is split, so it clamps far harder than fewer discs could while keeping the pedal usable. Sintered metallic friction material gives it the heat capacity to take repeated hard launches without fading, and it's formulated for smoother engagement than typical race discs, so it's aggressive without being purely on-off.
Twin Disc Or Triple Disc?
Being straight about where this sits, since it's a lot of clutch for an Si.
A triple disc is for serious power, the kind of build where a twin disc is no longer enough to hold what the engine makes. If you're making enough torque to slip a twin disc, or you're building a dedicated drag or high-power race Si, this is the clutch that holds it.
If your power level is within what a twin disc handles, Action's 7.25" twin disc for the Si holds up to 800 ft-lb, that's the more sensible choice, less clutch, a bit more forgiving, and still race-grade. Step up to this triple disc when the power genuinely demands the extra capacity.
Lightweight Billet Cover
The cover design does more than clamp.
It's a ventilated 6061-T6 billet aluminum cover, machined to trim weight and vented to help manage heat. Less rotating mass at the clutch means quicker throttle response and less rotational inertia for the engine to spin up, useful on a K20Z3 built to launch and accelerate as hard as this clutch implies.
High-strength steel pressure and floater plates handle the enormous clamping load, adding that clamp force without doubling your pedal effort. It's the combination that lets a triple disc hold 1200 ft-lb while staying drivable enough to actually launch.
The Flywheel Is Part Of The Assembly
Worth stating, since it's a complete package.
A multi-disc clutch includes its flywheel by design, the discs and floater plates stack against and mount to it, so the flywheel isn't a separate purchase, it's an integral part of the assembly. This kit comes with the matched flywheel the triple disc is built around.
That means you're getting the complete, engineered-as-a-unit assembly: discs, floaters, pressure plate, cover, and flywheel all designed to work together, with nothing else to source.
Checked By Hand Before It Ships
Worth knowing on a part holding this kind of power.
Every kit is inspected by Action Clutch's engineers, who bring over 60 years of collective experience, and each is signed off as safe before it ships. On a race clutch holding 1200 ft-lb, that per-unit quality check is the difference between consistent, reliable performance and a failure at the worst possible moment.
What To Expect
Two things that come with a triple disc, both normal.
The engagement is aggressive and on/off, that's the nature of an unsprung multi-disc race clutch, and it's the tradeoff for the holding power. And you need a pedal stop to avoid over-stroking the release system. Neither is a fault; both are characteristics of running a clutch this serious.

Part number ACR-2226-3D. 7.25" triple disc race clutch kit, includes flywheel. Race use only. Requires a pedal stop.
Who Should Grab This
This is for the 8th gen Si builder making serious power, drag, time attack, or dedicated race, who needs a clutch that holds 1200 ft-lb when a twin disc can't. Three sintered discs, a lightweight billet cover, and the matched flywheel that's part of the assembly. It's race-only, it needs a pedal stop, and it engages like the race component it is. If your power demands it, this holds it.

If running Graf gear set, please ensure you're running the V2 input shaft. The V1 input shaft is NOT compatable with our Multi-Disc Kits as the shaft placement is incorrect causing the top disc to overhang on the splines.
If running Gear-X gear set, please ensure your input shaft is machined fully. There are some gear sets that are circling around without complete machining which will cause any multi disc to not properly release.
Break-in Requirements 100 street miles / Keep RPM’s under 4500, no more than half-throttle, no boost (if applicable). Proper break-in is required in order to retain product warranty, ensure longevity and holding capacity.
Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment.
