Frequently Asked Questions
Product Info
Noise reduction in a clutch is largely achieved by increasing the angular torsional dampening capacity. UniClutch has 35 degrees of angularity, similar to a dual mass flywheel, and the patented 4-stage radial dampening centre uses a combination of springs in series and parallel encased in patented sleeves plus a urethane shock absorber stage. This allows the UniClutch to have up to twice the torque capacity of the traditional clutch with similar angularity to a dual-mass flywheel. This design is unique and one of the key technologies, which means the UniClutch will perform extremely well on a wide range of engines and increase the amount of driveline noise that is absorbed by the UniClutch over a traditional clutch.
Traditional Twin-Plate clutches are often noisy as the intermediate plate which separates the two frictional discs is floating when the clutch is disengaged. Users of these types of clutches will experience clutch plate rattle, and many aftermarket clutch manufacturers sell these products with a ‘buyer beware’ bulletin or video as the noise can be onerous. Mantic engineering has long had a suite of proven technologies to eliminate this rattle, and the UniClutch is no exception to this. After years of R&D and road/track-proven testing with Mantic, UniClutch utilizes a new noise suppressant system called silent shift technology. Silent shift technology utilizes spring loaded intermediate plates to stop them from rattling during engagement and disengagement.
Traditional heavy-duty/performance clutches rely on the pressure plate to have more clamp load which requires a stiffer diaphragm and more pedal effort to actuate the pressure plate to release the clutch. After extensive R&D by the UniClutch engineering team, the UniClutch has been designed in a way that requires less effort to actuate the clutch diaphragm to release the clutch. Thanks to this unique design, 90% of vehicle applications that are covered by UniClutch will offer a lighter or OE-level pedal effort.
No matter your application, the UniClutch will offer superior torque handling capacity compared to an OEM Clutch. When searching for your specific vehicle in the UniClutch catalogue, it will give you an indication of the potential torque capacity over an OEM clutch and the torque capacity rating for each UniClutch option.

Driving experience
As the UniClutch has 4 friction surfaces compared to a traditional clutch which has 2, it is critical that a proper bedding-in procedure is undertaken to ensure the product functions as intended.
During the bedding-in period, you may experience some minor clutch shudder which is normal. The friction surfaces need to mate to create full, even contact. The Bed in period allows some friction material to transfer from the friction discs to the intermediate plates and pressure plate surfaces which provides a uniform coefficient of friction for the entire clutch.
During the initial bedding-in phase, the coefficient of friction of the clutch discs will drop and then slowly increase over time to a stable level.
During the bed-in period, if the vehicle RPM increases at a rate that is not proportionate with the normal rotation of the wheels, you must back off the throttle to ensure you do not generate excessive heat. If excessive heat is generated, it will not allow the product to reach its full potential.
To correctly bed-in your new UniClutch, we recommend operating the vehicle in normal driving conditions such as regular city driving. During this period, the clutch must be actuated regularly at low RPM, such as take-off and normal shifting for at least the first 1000kms.
Failure to appropriately bed-in the UniClutch may result in glazing or damage of the friction surfaces resulting in shudder, slippage and noise during operation and not allow the clutch to transmit the torque to its maximum ability.
Failing to properly “Bed, or Wear In” the clutch will immediately void any warranty on the clutch.
While the UniClutch replaces OE clutches, it will not feel exactly like an OE clutch. Most aftermarket twin plates on the market will offer more compromises to the driveability & NVH comparable to the OE clutch. The UniClutch will provide all the benefits of a twin plate clutch with fewer compromises. In a small percentage of UniClutch applications, there may be a compromise with increased pedal effort or levels of shudder compared to the OE clutch it is replacing.
UniClutch has been designed to feel like an OE clutch or lighter in most applications. When searching for your specific vehicle in the UniClutch catalogue, it will give you an indication of the expected pedal effort after the UniClutch is installed.
In most instances, the release point will be like OEM. When searching for your specific vehicle in the UniClutch catalogue, it will give you an indication of the potential clutch release point.
Converting from a dual mass to a solid mass flywheel will usually mean that you will experience an increase in the NVH (driveline vibration and noise). While the UniClutch does have superior noise and vibration dampening thanks to the patented 4-stage radial dampening centre (RDC), we still expect that you may experience an increase in the NVH generated by the engine as a result of removing the dual mass flywheel.
Installation info
Yes, there are instructions for every single UniClutch installation, these instructions can be found by scanning the QR code on your product box and going through to the online catalogue page and downloading the specific installation instructions for your vehicle application. The correct setup and installation are critical for the product to function as manufactured. Every UniClutch is built and tested before and will be recorded as functioning correctly before leaving CI. If these instructions are not followed, it can cause installation issues which will lead to the product not functioning correctly and the warranty being void.
No, it is critical to the correct operation of the UniClutch that the height spacers are installed as outlined in the specific vehicle install instructions.
No flywheel machining is required as the UniClutch does not utilize the flywheel as a friction surface like a traditional clutch. As the UniClutch is totally sealed, the flywheel only used as a bolt face so that the UniClutch can transmit the power from the engine to the gearbox. It is recommended that an installer carefully inspects the current flywheel to ensure it has no major defects that would prevent it from being reused when installing the UniClutch.
If your dual mass flywheel is still within the recommended factory tolerance, then it can be retained and reused when installing the UniClutch. If it is not within the factory tolerance, then a new DMF should be used or a Clutch industries solid mass flywheel (DMR) could be used in place of the DMF.
It is always recommended to review the spigot bearing at the time of the old clutch removal, if the condition is unknown best practice is to replace it with a new item.
It is best practice to ensure that the bell housing and gearbox case is completely cleaned and free of anything that could cause contamination to your new UniClutch. Any UniClutch found to have any external contamination will void its warranty.
Yes, if the rear main seal is leaking, the engine oil could contaminate your new UniClutch, which will affect the operation of the clutch and its performance. Any UniClutch found to have any external contamination will void its warranty.
It is good practice with any clutch replacement to look over the reason why the original clutch needed to be replaced and ensure that any components that could have caused an issue are reviewed. Look over the hydraulic system(Master cylinder, slave cylinder or clutch dampener etc) and any other components in the clutch system (Fork , pivot point etc) to ensure they in working and reusable condition. If there is any doubt about the condition of these components it is recommended that they are replaced with new items.
If you have used the correct components for the installation as outlined in your specific UniClutch installation guide, then you can dispose of the other components left in the fitment kit as they will not be required.

I have an aftermarket solid mass flywheel conversion installed in my vehicle. Can I use a UniClutch?
If you have a CI-branded Solid Mass Flywheel, then the UniClutch can be fitted with the correct fitting kit. Suppose another branded Solid Mass Flywheel is fitted. In that case, UniClutch cannot be guaranteed to work if that manufacturer has designed their Solid Mass Flywheel to use a different pressure plate bolt pattern from OEM. It would be recommended to purchase a new CI SMF for maximum compatibility.
If your aftermarket lightweight flywheel is a replacement for the OE flywheel, just lighter, then yes, you can. If your lightened flywheel has been made to suit a specific clutch pressure plate, then you may not be able to use UniClutch, contact the UniClutch technical team for clarity.
Spare parts
You can purchase any of the parts in the UniClutch fitment kit as individual spare parts. However, you cannot purchase any components in the assembled sealed UniClutch unit. You can contact the UniClutch sales or technical team for assistance with purchasing available spare parts.
No, each UniClutch is individually built and tested as a matched set of components. Any of the internal components of the UniClutch cannot be purchased separately. A complete UniClutch unit would need to be purchased if it’s required.
You can purchase a new UniClutch sport or track and reuse your existing fitment kit. The fitment kit components installed on the flywheel must be reviewed before installing the new UniClutch, if there is any doubt about the condition of those components, it is better to replace them with a new fitment kit.
