Important conversion-clutch warning
The factory clutch disc is advertised at 8-7/8 inches, while the ClutchMaxPRO disc measures 8-5/8 inches.
| Component | Advertised diameter |
|---|---|
| Original factory disc | 8-7/8 inches |
| ClutchMaxPRO disc | 8-5/8 inches |
| Difference | 1/4 inch smaller |
ClutchMaxPRO states that the smaller disc reduces rotating mass. A smaller diameter can reduce rotational inertia, but clutch performance also depends on pressure-plate load, friction material, effective friction radius and heat capacity.
Do not reuse the original pressure plate with the smaller ClutchMaxPRO disc. The replacement disc and pressure plate are engineered as a matched set and must be installed together.
Is a flywheel included?
No flywheel is listed among the included components.
The statement that the conversion “must be used together as a kit” refers to the supplied clutch disc, pressure plate, bearings and related components. It does not appear to mean that a flywheel is included.
Before installation, ask the seller whether the kit:
- Reuses the original flywheel
- Requires the factory flywheel to be resurfaced
- Requires a specific replacement flywheel
- Has an approved flywheel step-height specification
- Works with single-mass conversion flywheels
- Requires different pressure-plate hardware
This distinction should be clearly stated on the product page. Removing a transmission and discovering that “complete kit” was feeling philosophical that day is generally frowned upon.

No horsepower or torque capacity is provided in the supplied listing. Avoid advertising the kit for forced-induction or high-output applications without a documented torque rating.
OEM-style driving characteristics
The full-face clutch disc is intended to maintain reasonable street manners. Compared with a puck-style ceramic clutch, drivers should expect:
- Smoother engagement
- Better low-speed modulation
- Manageable pedal effort
- Reduced chatter
- Predictable commuting behavior
- Appropriate operation for stock or mildly modified engines
A heavy-duty pressure plate may produce slightly firmer pedal effort than the original assembly, but this should remain more civil than a dedicated competition clutch.
Read the Pro Street performance clutch guide for a comparison of organic, Kevlar and ceramic clutch materials.
Why use a smaller clutch disc?
ClutchMaxPRO claims the reduced disc diameter lowers rotating mass for improved performance and service life.
Reducing clutch-disc diameter may provide:
- Slightly lower rotational inertia
- Quicker synchronization during shifts
- Reduced mass carried by the transmission input shaft
- More responsive engine-speed changes
There are potential tradeoffs. A smaller disc can have less friction area and thermal mass, depending on its inner diameter and construction. Clamping load and friction material must compensate for those changes.
Because no detailed engineering data or torque rating is supplied, describe these as manufacturer-stated benefits rather than independently established performance gains.
Who should buy this kit?
This clutch kit is best suited to:
- Stock K24-powered Accord and TSX models
- Daily-driven manual-transmission vehicles
- Cars with basic intake or exhaust modifications
- Drivers seeking factory-style engagement
- Vehicles needing a complete clutch refresh
- Owners willing to keep the matched conversion components together
A higher-capacity performance clutch may be more appropriate for:
- Turbocharged K24 builds
- Supercharged engines
- High-torque tuning
- Repeated drag launches
- Dedicated track vehicles
- Engine-swapped applications

Signs the clutch may need replacement
Common symptoms include:
- Engine speed increasing without matching acceleration
- Slipping in higher gears
- Burning friction-material odor
- Engagement near the top of pedal travel
- Chatter during takeoff
- Difficulty selecting gears
- Release-bearing noise
- Reduced acceleration under load
Hydraulic faults can create similar symptoms. Inspect the clutch master cylinder, slave cylinder, hydraulic line and pedal adjustment before removing the transmission.
Flywheel inspection
Because a flywheel is not included, inspect the existing flywheel for:
- Heat spots
- Cracks
- Scoring
- Warpage
- Excessive wear
- Incorrect step height
- Damaged ring-gear teeth
Resurface the flywheel only when permitted by Honda and ClutchMaxPRO specifications. Confirm that machining will preserve the correct pressure-plate mounting relationship.
If the vehicle already has an aftermarket flywheel, verify compatibility before installing this conversion clutch.
Installation recommendations
While the transmission is removed, inspect:
- Rear main engine seal
- Transmission input-shaft seal
- Clutch fork and pivot
- Release-bearing guide
- Master and slave cylinders
- Hydraulic clutch hose
- Axle seals
- Engine and transmission mounts
- Flywheel and pressure-plate bolts
Before installation:
- Confirm the vehicle, engine and transmission.
- Compare the new and original clutch assemblies.
- Verify the 24-spline hub.
- Keep the ClutchMaxPRO disc and pressure plate together.
- Check clutch-disc orientation.
- Inspect or resurface the flywheel correctly.
- Clean every friction surface.
- Tighten the pressure plate gradually.
- Follow Honda’s torque specifications.
- Bleed and adjust the clutch hydraulic system.
Break-in procedure
Follow the instructions included with the exact ClutchMaxPRO kit. A full-face street clutch generally requires several hundred miles of moderate driving.
During break-in:
- Avoid hard launches
- Avoid full-throttle acceleration
- Stay out of boost, if applicable
- Do not perform dyno pulls
- Avoid track use
- Minimize unnecessary clutch slipping
- Use repeated normal engagement cycles
Steady highway driving provides very few engagement cycles and should not represent the entire break-in period.
Warranty coverage
The kit is advertised with a 12-month or 15,000-mile limited warranty covering qualifying fitment, material and functional defects.
Keep:
- Proof of purchase
- Installation invoice
- Flywheel resurfacing receipt
- Product packaging
- Component part numbers
- Photographs from installation
- Break-in documentation
Incorrect component mixing, improper flywheel preparation, contamination or abuse may affect warranty eligibility.
Final verdict
The ClutchMaxPRO conversion clutch is a practical option for compatible 2.4L manual-transmission Honda Accord and Acura TSX models. Its full-face disc should preserve reasonable street manners, while the smaller diameter may modestly reduce rotating mass.
The important requirement is keeping the 8-5/8-inch disc paired with its matching ClutchMaxPRO pressure plate. Confirm flywheel requirements and exact vehicle fitment before installation, especially because the package itself does not include a flywheel.
