If you are shopping Mitsubishi Evo X clutch kits, the first thing to know is that the 2008–2015 Lancer Evolution X runs the 4B11T 2.0L turbo — a completely different engine and clutch from the 4G63-powered Evo VIII/IX. That means Evo 8/9 clutches do not fit, and the parts below are the ones built specifically for the CZ4A 5-speed. The factory 4B11T makes roughly 291 hp and 300 lb-ft, and the OEM clutch starts slipping once a tuned Evo X pushes past 350–400 wheel-torque. In our Tampa, FL shop we sell these six kits — from a $567 budget single to a $2,312 Exedy Hyper Twin — more than almost any other Evo drivetrain part. This guide compares Exedy, ACT and Competition Clutch head-to-head so you buy once.
Our Verdict
For a big-power street/track Evo X, the Exedy Hyper Twin Cerametallic is the clutch to buy; for most 350–450 whp street cars, the Exedy Stage 2 single is the value sweet spot.
The twin-disc Exedy Hyper Twin ($2,312) holds serious boost while keeping a usable street pedal. Want the same twin-disc security with a lighter wallet hit and a factory-feel pedal? The ACT Mod Twin HD is rated to 700 ft-lb. On a budget, the Competition Clutch Stage 2 covers stock-to-mild builds for $567.
Shop Our Top Pick →Why the Evo X (4B11T) Needs Its Own Clutch
The Evo X clutch is a 4B11T-specific part — it does not interchange with the 4G63 clutch used in the Evo VIII/IX. The CZ4A chassis (2008–2015) came two ways: the GSR with a 5-speed manual and the MR with the SST twin-clutch automated gearbox. Every kit in this guide is for the GSR 5-speed manual — SST cars use a wet dual-clutch pack, not a bolt-in disc.
Stock, the 4B11T makes about 291 hp and 300 lb-ft, and the OEM single-disc organic clutch is a known weak point once you add boost. A simple access-port tune, bigger turbo, or E85 pushes wheel torque past what the factory clutch can clamp, and it slips under full boost in third and fourth gear. That is why Evo X owners upgrade early — a $567 to $2,312 clutch is cheaper than a burned flywheel and a tow bill. The right choice depends on power target, how often you drive in traffic, and whether you can live with a heavier pedal.
Organic vs Cerametallic vs Twin-Disc: The 30-Second Version
Clutch choice comes down to disc material and disc count. An organic (sprung) disc engages smoothly and feels near stock — ideal for daily driving and mild power. A cerametallic (paddle) disc uses a metallic friction puck that grabs harder and holds more torque, at the cost of a more abrupt, on/off engagement. Going from one disc to a twin-disc setup roughly doubles friction area, so it holds far more torque without a brutal pedal — the reason serious Evo X builds run twins. Here is how each kit in this comparison lands.
The 6 Best Evo X Clutch Kits Compared
This is the clutch for the Evo X owner chasing big boost. The Hyper Twin uses two cerametallic discs on a sprung hub, so it clamps like a race clutch but still engages smoothly enough to sit in Tampa traffic. It is the most capable street-drivable Exedy option for the 4B11T and the reason it is our overall top pick for 450+ whp builds.
Want twin-disc holding power with the softest possible pedal? The Twin-Organic pairs two organic discs for near-OEM engagement and drivability, while still tolerating far more torque than any single-disc setup. It is the pick for a high-power Evo X that still sees daily-driver duty, and it undercuts the Hyper Twin by about $40.
ACT is the only kit here with a published torque number on the box: 700 ft-lb. The Mod Twin HD uses a sprung mono-drive hub for smoother street engagement than a rigid race twin, and at $1,988 (before the extra 5% off) it is the most affordable twin-disc in this comparison. Note the 5-speed-only fitment — it will not work on the SST.
Twin-disc kits nearly double friction area, holding big torque without a race-only pedal.
For the largest slice of Evo X owners — a Stage 2 tune, upgraded turbo, and a car that still gets driven — the Stage 2 Cerametallic single is the value sweet spot at $1,112. The paddle disc grabs harder than the organic Stage 1 for stronger clamp, without stepping up to twin-disc money. Expect a firmer, quicker engagement than stock.
Running a near-stock or lightly tuned Evo X and want a fresh clutch that feels factory? The Stage 1 Organic is the answer at $833. Its sprung organic disc engages smoothly and quietly, so it is the easiest kit here to live with in traffic — just do not ask it to hold a big-turbo, E85 tune.
If the budget is tight, the Competition Clutch Stage 2 gets a fresh, stronger-than-stock clutch under your Evo X for $567 — less than a third of the twin-disc kits. Its Steelback Brass Plus disc adds clamp for stock-to-mild power. Check the fitment window: this listing covers 2008–2010 Evo X, so 2011–2015 owners should choose one of the Exedy or ACT kits above.
Key Specifications — Exedy Hyper Twin (Top Pick)

| Competition Clutch Stage 2 | Single Brass Plus | Stock to mild (08–10) | Firm street | $567.00 |
Power ranges above are general guidance for a street-driven 4B11T; your safe holding torque depends on tune, flywheel, and how the car is driven. When in doubt, size up — a clutch that slips at your target power will not last.
Exedy twin-disc kits ship with a matched flywheel for the 4B11T 5-speed.

Installing an Evo X Clutch: Break-In and Fitment Notes
Whichever kit you choose, budget for a few supporting parts and a proper break-in. The Exedy and ACT twin-disc kits include a matched flywheel, so plan to replace the pilot and throwout (release) bearing at the same time — they are inexpensive and the transmission is already out. Inspect the slave cylinder and clutch line while you are in there; a tired hydraulic system masks itself as a “bad clutch” and will undo a fresh install.
Break-in matters most on the cerametallic and twin-disc kits. Organic discs (Exedy Stage 1 and Twin-Organic) seat quickly and feel normal almost immediately. Cerametallic paddle discs (Exedy Stage 2 and Hyper Twin) need roughly 300–500 miles of easy, varied driving to bed the friction material before you launch or hold high boost — skip it and you risk glazing and premature slip. Twin-disc kits also idle with a light rattle; that floating center disc is normal, not a defect. On the 4B11T 5-speed, torque the pressure plate to spec in a star pattern and set the release bearing per the instruction sheet. Plan on 4–6 hours of labor at a shop, or a full day in the driveway.
Frequently Asked Questions
What is the best clutch for a Mitsubishi Evo X?
The best all-around clutch for a big-power 2008–2015 Evo X is the Exedy Hyper Twin Cerametallic ($2,311.92), a twin-disc kit that holds 450+ whp while staying street-drivable. For most Stage 2 street cars (350–450 whp), the single-disc Exedy Stage 2 Cerametallic ($1,112.34) is the better value, and the ACT Mod Twin HD ($1,988) is the most affordable twin-disc, rated to 700 ft-lb.
Does an Evo 8/9 clutch fit an Evo X?
No. The Evo VIII/IX uses the 4G63 engine and a different clutch and flywheel than the Evo X, which runs the 4B11T 2.0L turbo. You must buy an Evo X (CZ4A) 4B11T-specific clutch — every kit in this guide is built for the 2008–2015 Evo X 5-speed manual (GSR).
How much horsepower can the stock Evo X clutch hold?
The factory Evo X clutch is matched to the stock 291 hp / 300 lb-ft output and typically begins to slip once a tuned car exceeds roughly 350–400 wheel-torque. A basic access-port tune, larger turbo, or E85 will push most Evo X cars past that point, so a clutch upgrade is one of the first supporting mods owners buy.
Do these clutches fit the Evo X MR (SST)?
No. Every kit here is for the GSR 5-speed manual only. The Evo X MR uses the SST twin-clutch automated gearbox, which has a wet dual-clutch pack rather than a bolt-in disc clutch, so these single- and twin-disc kits do not apply.
Single-disc or twin-disc clutch for the Evo X?
Choose a single-disc clutch (Exedy Stage 1 or Stage 2) for stock-to-Stage-2 power up to roughly 450 whp — it is cheaper, lighter on the wallet, and simpler. Step up to a twin-disc (Exedy Hyper Twin, Exedy Twin-Organic, or ACT Mod Twin HD) when you are targeting 450+ whp, since twin discs nearly double friction area to hold big torque without a race-only pedal.
What is the cheapest Evo X clutch upgrade?
The Competition Clutch Stage 2 Steelback Brass Plus is the budget pick at $567, covering stock-to-mild power on 2008–2010 Evo X models. Owners of 2011–2015 cars, or anyone chasing bigger power, should move up to the Exedy Stage 2 single ($1,112.34) or a twin-disc kit.
