Exedy / CMPRO K20 K24 Clutch Kit Specifications

Vehicle Fitment

According to the supplied application data, this kit is intended for select:

The application list is broad, and K-series Honda/Acura vehicles were offered with different transmissions, flywheels and clutch configurations.

Always verify:

year + model + engine + transmission + flywheel

before ordering.

Important Clutch Pedal Adjustment Note

The supplied product information states:

“May require clutch pedal adjustment for proper engagement.”

That warning should not be ignored.

After installation, clutch pedal free play and master-cylinder pushrod adjustment may affect:

• Engagement height
• Complete clutch release
• Pedal travel
• Shifting quality
• Release-bearing preload

An incorrectly adjusted pedal can create symptoms that resemble a defective clutch.

Do not compensate for a hydraulic or installation problem by randomly adjusting the pedal.

Use the proper Honda or Acura service procedure for the exact vehicle.

K20 and K24 Fitment Does Not Mean Universal K-Series Fitment

This package covers several K20 and K24 vehicles, but that does not mean it fits every Honda K-series combination.

Honda produced numerous:

• K20 engine variants
• K24 engine variants
• 5-speed transmissions
• 6-speed transmissions
• Accord transmissions
• RSX transmissions
• Civic Si transmissions
• TSX transmissions

The K-series became one of Honda’s most popular swap platforms precisely because so many combinations are possible.

That makes transmission verification even more important.

Exedy Clutch Components

EXEDY supplies the clutch disc and pressure plate in this package.

EXEDY is a long-established clutch manufacturer whose parent company dates to 1923. EXEDY Globalparts Corporation states that the company supplies manual clutches, flywheels and other powertrain components for OEM and aftermarket applications.
https://www.exedyusa.com/corporate-profile/

For its OE replacement clutch products, EXEDY states that the clutch cover assemblies are tested for proper clamp load and release characteristics, while its clutch discs use proprietary friction materials and spring dampers designed to reduce drivetrain vibration.

CMPRO Heavy-Duty OEM-Style Flywheel

The package pairs the Exedy clutch components with a:

ClutchMaxPRO HD OEM-style flywheel.

Replacing the flywheel during clutch service eliminates many of the concerns associated with reusing an old friction surface.

An older flywheel can develop:

• Heat checking
• Hot spots
• Grooves
• Glazing
• Cracks
• Uneven friction surfaces
• Excessive previous machining

A new flywheel gives the clutch disc a fresh surface for proper bedding.

Why Replace the Flywheel With the Clutch?

EXEDY specifically recommends that the flywheel be resurfaced or replaced, depending on application, when installing an OE replacement clutch.
https://www.exedyusa.com/faq/

This package includes the flywheel, so there is no need to rely on an unknown or potentially worn original friction surface.

That can save time during installation and reduce uncertainty about:

• Surface condition
• Minimum thickness
• Prior resurfacing
• Heat damage

Acura RSX Fitment

The supplied listing includes:

2002–2006 Acura RSX 2.0L K20

applications.

That includes both the standard RSX and:

RSX Type-S

according to the seller.

However, the RSX lineup used multiple K20 engines and different transmissions.

For example, the base RSX and Type-S are not mechanically identical.

Do not assume clutch interchangeability based only on the RSX badge.

For more background on K20 variations, see:

https://my.prostreetonline.com/2014/10/19/faq-k20-engine/

Acura RSX Type-S Fitment

The RSX Type-S is one of the most important applications in this listing because it is frequently modified.

Before ordering for a Type-S, verify:

• Model year
• Transmission
• Flywheel
• Previous clutch modifications
• Engine swap history

A 20-plus-year-old RSX Type-S may no longer have the transmission or flywheel it left the factory with.

Acura TSX Fitment

The supplied listing includes:

2004–2014 Acura TSX 2.4L K24

applications.

This is a broad range spanning multiple model generations.

The TSX used K24 engines and manual transmissions that made the platform popular with K-series enthusiasts.

However, transmission and clutch specifications vary by generation and configuration.

Verify exact fitment before ordering.

Acura ILX Fitment

CMPRO lists:

2013–2015 Acura ILX 2.4L K24

applications.

The 2.4L ILX shares important drivetrain architecture with other performance-oriented K24 Honda/Acura applications, but application-specific verification is still required.

Acura CSX Fitment

The supplied fitment includes:

2006–2011 Acura CSX 2.0L K20

models.

The Acura CSX was sold primarily in Canada, so U.S.-based catalogs may not always show it prominently.

If ordering for a CSX, confirm the exact transmission and engine configuration rather than substituting Civic fitment automatically.

2002–2011 Honda Civic Si Fitment

CMPRO lists:

2002–2011 Honda Civic Si 2.0L K20

applications.

This spans more than one Civic generation.

Earlier EP3 Civic Si models and later eighth-generation Civic Si models use different K20 variants and transmission designs.

Our K20 EP3 Swap Guide discusses some of those drivetrain differences:

https://my.prostreetonline.com/2016/04/21/k20-ep3-swap-guide-need/

2012–2015 Honda Civic Si Fitment

For the ninth-generation Civic Si, the supplied listing includes:

2012–2015 Honda Civic Si 2.4L K24.

This generation moved away from the earlier 2.0L K20 and into the larger-displacement K24 family.

That distinction matters when shopping for:

• Clutch kits
• Flywheels
• Transmissions
• Swap parts

Do not order purely by the words:

Civic Si.

Confirm the engine and transmission generation.

Honda Accord K24 Fitment

The supplied product data lists:

2003–2012 Honda Accord 2.4L K24

applications.

The Accord deserves extra attention because manual-transmission availability varied by:

• Model year
• Trim
• Body style
• Market

This kit is only relevant where the vehicle has the correct manual K24 drivetrain.

Do not assume fitment for an automatic Accord.

K20 vs K24 Clutch Selection

K20 and K24 engines share substantial architecture, but their transmission combinations can differ.

A clutch package should be selected based on the:

transmission and flywheel combination

rather than engine displacement alone.

This becomes even more important on swaps.

For a broader overview of selecting engines and transmissions for K-series builds, see:

https://my.prostreetonline.com/2014/09/25/k20-swap-guide-what-you-need-to-swap-a-k20/

K-Series Swapped Cars Require Extra Verification

If you’re buying this package for a K-swapped vehicle, stop before ordering and identify exactly what drivetrain is installed.

A swapped Civic might use:

• RSX base transmission
• RSX Type-S transmission
• EP3 Civic Si transmission
• 8th-gen Civic Si transmission
• TSX transmission
• Accord transmission
• Mixed K20/K24 engine combination

The engine code alone does not determine which clutch is required.

Our K-series swap guide explains why transmission choice matters:

https://my.prostreetonline.com/2016/01/05/how-to-k-series-swap/

Exedy OEM Replacement Clutch vs Performance Clutch

This package uses Exedy OEM-style clutch components rather than an EXEDY Stage 1 or Stage 2 performance clutch.

That distinction matters.

EXEDY states that its OE replacement clutch kits are rated for:

OEM power levels.

For engines producing substantially more torque than stock, EXEDY recommends looking at its performance clutch lines instead.
https://www.exedyusa.com/faq/

Good Choice for a Daily-Driven K-Series Honda

This package is best suited to vehicles used primarily for:

• Daily driving
• Commuting
• Street use
• Factory restoration
• Stock engines
• Mild bolt-on modifications

For these applications, factory-like clutch behavior is generally more useful than aggressive engagement.

Modified K20 and K24 Engines

If the engine has modifications such as:

• Turbocharger
• Supercharger
• High-compression build
• Large camshafts
• Built cylinder head
• Significant ECU tuning

the clutch should be selected using actual torque output.

Do not assume an OEM replacement clutch will hold significantly more torque simply because the flywheel is described as heavy duty.

Turbo K-Series Applications

A turbocharged K20 or K24 can exceed OEM clutch capacity quickly.

For turbo builds, evaluate:

• Peak torque
• Boost pressure
• Tire grip
• Vehicle weight
• Launch frequency
• Intended competition use

Use an appropriately rated performance clutch when required.

What Comes in the Kit?

According to the supplied product description, this package contains:

• ClutchMaxPRO HD OEM-style flywheel
• Exedy pressure plate
• Exedy clutch disc
• Release bearing
• Pilot bushing
• Grease pack
• Alignment tool
• Installation guide

That gives the installer the major components needed for a comprehensive clutch and flywheel replacement.

Release Bearing Included

A new release bearing is included.

Because transmission removal is required for clutch replacement, reusing an old release bearing generally creates unnecessary risk.

A worn release bearing may cause:

• Noise with the clutch pedal depressed
• Rough release operation
• Premature failure

Inspect all associated release hardware during installation.

Pilot Bushing Included

The kit also includes a:

pilot bushing.

Install the appropriate component where specified for the exact K-series drivetrain.

Follow the factory service procedure for the vehicle and transmission.

Grease Pack Included

Lubrication should only be applied to the appropriate clutch-release and spline contact areas.

Do not put grease on:

• Clutch disc friction surfaces
• Flywheel friction surface
• Pressure plate friction surface

A clutch depends on friction.

Removing that friction is impressively effective but generally not part of the installation procedure.

Use the Alignment Tool

The clutch disc must be centered before the pressure plate is fully tightened.

The included alignment tool helps position the disc relative to the flywheel and pilot location.

If the clutch disc is not centered, the transmission input shaft may refuse to slide into place.

Never use bellhousing bolts to force the transmission against the engine.

Pressure Plate Installation

Install the pressure plate:

• Evenly
• Gradually
• In sequence
• To factory torque specification

EXEDY specifically recommends using the vehicle manufacturer’s pressure-plate bolt torque specification.
https://www.exedyusa.com/faq/

Replace or Inspect Flywheel Bolts

While the flywheel is removed, inspect the flywheel bolts and follow the appropriate Honda or Acura service information regarding replacement and tightening procedures.

Our K20 Swap Guide also discusses K-series flywheel and clutch fasteners:

https://my.prostreetonline.com/2014/09/25/k20-swap-guide-what-you-need-to-swap-a-k20/

Inspect the Rear Main Seal

Removing the flywheel gives access to the rear of the engine.

Inspect for:

• Oil seepage
• Active leakage
• Contamination

A leaking rear main seal can contaminate the new clutch disc and cause:

• Slipping
• Chatter
• Burning odor
• Premature failure

Fix active leaks before installing the new flywheel and clutch.

Inspect the Transmission Input Area

Check the bellhousing and input shaft area for transmission-fluid leakage.

Oil contamination from either side of the bellhousing can ruin a new friction disc.

Check the Clutch Master Cylinder

A clutch that does not disengage correctly may have a hydraulic problem rather than a friction-disc problem.

Inspect the:

• Clutch master cylinder
• Slave cylinder
• Hydraulic hose
• Fluid level
• Pedal adjustment

before assuming the clutch itself is defective.

Check the Slave Cylinder

K-series vehicles use hydraulic clutch-release systems.

A failing slave cylinder can cause:

• Poor release
• Hard shifting
• Low pedal
• Fluid leakage
• Gear grinding

A hydraulic fault can remain even after installing a new clutch.

Why Pedal Adjustment Matters on This Kit

Because the supplied product listing specifically warns that clutch pedal adjustment may be required, pedal setup deserves careful attention after installation.

Incorrect adjustment may:

• Keep the release bearing partially loaded
• Prevent full clutch engagement
• Prevent full clutch release
• Change engagement height

Follow the exact vehicle’s service procedure.

Do not simply adjust the pedal until it “feels right.”

Clutch Break-In

EXEDY recommends a break-in period for its OE replacement clutch kits of approximately:

500 city miles or 1,000 highway miles

with easy driving and no high-RPM shifts, quick shifts or hard launches during that period.
https://www.exedyusa.com/faq/

Follow any instructions supplied with the actual kit first.

Why Break-In Matters

A new clutch disc, pressure plate and flywheel need time to develop a consistent friction contact pattern.

Aggressive use immediately after installation can contribute to:

• Hot spots
• Glazing
• Uneven transfer
• Chatter
• Premature wear

Normal stop-and-go engagement cycles are generally more useful during break-in than simply accumulating highway mileage.

Symptoms of a Worn K-Series Clutch

Common signs include:

• Engine RPM rises without proportional acceleration
• Clutch slips in higher gears
• Burning clutch smell
• High engagement point
• Chatter during takeoff
• Difficulty transmitting torque

Clutch slip often becomes most noticeable under heavy load.

Hard Shifting Doesn’t Automatically Mean a Bad Clutch

Other possible causes include:

• Clutch hydraulic problems
• Incorrect pedal adjustment
• Worn synchros
• Shifter cable issues
• Transmission damage
• Improper clutch release

Diagnose first.

Replacing the clutch, master cylinder, slave cylinder and transmission simultaneously is one way to find the problem, but there are cheaper diagnostic strategies.

Inspect the Shifter System

K-series manual transmissions use cable-operated shifters.

Inspect:

• Shift cables
• Cable bushings
• Shifter base
• Cable adjustment
• Transmission selector mechanism

if the car has difficult or inconsistent gear selection.

Our K-Series Transmission Differences guide covers additional drivetrain considerations:

https://my.prostreetonline.com/2015/02/20/k-series-transmission-differences/

Exedy OEM Clutch Warranty

EXEDY currently states that its standard OEM replacement clutch kits carry a:

12-month / 20,000-mile warranty

against manufacturing defects, subject to its warranty conditions.

EXEDY also states that performance use and improper flywheel preparation can affect warranty eligibility.
https://www.exedyusa.com/warranty-policy/

Because this product combines Exedy components with a CMPRO flywheel, verify which manufacturer’s warranty applies to each component of the actual package before installation.

CMPRO Warranty

The supplied seller information advertises a ClutchMaxPRO limited warranty of:

12 months or 15,000 miles

for covered issues.

Since mixed-brand packages can have different warranty terms for individual components, review the current terms at purchase rather than assuming the entire package follows one warranty policy.

Exedy + CMPRO vs Complete Exedy Kit

This package is not the same as buying a complete EXEDY-manufactured clutch-and-flywheel kit.

This Package

Uses:

• Exedy clutch disc
• Exedy pressure plate
• CMPRO flywheel

Complete EXEDY Package

Would use EXEDY-designated components throughout where available.

That distinction should be clearly stated in the product description.

Who Should Consider This Kit?

This package makes the most sense for someone with a compatible:

• Acura RSX
• Acura RSX Type-S
• Acura TSX
• Acura ILX
• Acura CSX
• Honda Accord
• Honda Civic Si

who wants a complete OEM-style clutch and flywheel replacement rather than reusing the old flywheel.

Who Should Verify Further?

Additional verification is particularly important if:

• The vehicle is engine swapped
• The transmission has been swapped
• The car has an aftermarket flywheel
• The engine is turbocharged
• The engine makes substantially more than factory torque
• The vehicle has a mixed K20/K24 combination

K-series swaps are famous for mixing and matching components.

That’s great for building cars.

It’s less great for ordering clutch parts based solely on the VIN.

Final Fitment Checklist

Before ordering, verify:

Year → Make → Model → Engine → Transmission → Flywheel → Clutch Application

Supplied Applications

2006–2011 Acura CSX — 2.0L K20

2013–2015 Acura ILX — 2.4L K24

2002–2006 Acura RSX / RSX Type-S — 2.0L K20

2004–2014 Acura TSX — 2.4L K24

2003–2012 Honda Accord — 2.4L K24

2002–2011 Honda Civic Si — 2.0L K20

2012–2015 Honda Civic Si — 2.4L K24

Also remember the manufacturer’s note:

Clutch pedal adjustment may be required for proper engagement.

Final Take

The Exedy clutch kit and CMPRO flywheel package for Honda and Acura K-series vehicles is a practical choice for owners looking to replace both major clutch components and the flywheel during one repair.

It combines:

Exedy clutch disc

Exedy pressure plate

CMPRO HD OEM-style flywheel

release bearing

pilot bushing

alignment tool

and:

installation hardware.

Its strongest application is a stock or near-stock K20/K24 vehicle that needs reliable everyday clutch operation.

For heavily modified K-series builds, especially turbocharged cars, use actual torque output to select an appropriately rated performance clutch instead.

And on a swapped Honda, remember the golden rule:

identify the transmission before ordering the clutch.

The K20 badge on the valve cover doesn’t tell you what’s bolted to the other side of the engine.
