The New FX 725 PRO Series twin and triple disc units are the latest multi disc clutch kits developed by Clutch Masters for 2026. For over 15 years Clutch Masters has offered our traditional FX 725 kit which has been relied on by racers and enthusiast around the globe. With our continued focus on development and striving for perfection along the way, we have gone back to the drawing board to revamp and improve the FX 725. As a result, Clutch Masters has developed the FX 725 PRO series which has not only improved the product in several aspects, but we can confidently say this is the best 7.25” clutch option on the market today.

By increasing the pressure plate stands to 12-steel post versus the FX725 standard aluminum 6-post, the unit has a better structural integrity to handle more torque, abuse, and heat. High horsepower / race applications would cause the aluminum post to flex and wear due to the high amount of stress. To solve this weak point the stands were doubled to 12 and made from 4140 heat treated steel.

Clutch Masters is also very proud to say that these units are 100% made in the USA. Investing in the infrastructure to design, manufacture, and assemble in house was a crucial step to be able to achieve an improved clutch design for today's market. Being in the driver seat to make quick changes during the R&D phase allowed Clutch Masters to make improvements based off the feedback from the race teams who had a huge input in developing the FX 725 PRO. These clutch kits are SFI Certified, meeting performance standards for the automotive and motorsport industry.

Flywheels are made for each specific application in either aluminum or steel. Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert. Steel flywheels are machined from 1045 billet cores and are then black oxide treated for rust prevention.
