Sonic Clutch-Flywheel-Assembly Chevy (Late)

MACH I Button Clutch-Flywheel-Assemblies offer a cost-effective means to upgrade from a heavy OEM-style clutch assembly. They provide a significantly lower moment-of-inertia and a greater level of reliability then OEM-style clutches. If your track/series rules do not allow 5.5" (or smaller) clutches, or long-term durability is most desired, MACH I clutches are your ideal choice.

Button Clutch-Flywheel-Assemblies Include: 7.25" MACH I clutch, disc(s), billet steel button flywheel, clutch-to-flywheel bolt kit.

Note: MACH I Button CFAs are neutral balance, unless indicated.

MACH II Clutch-Flywheel-Assemblies are the ideal choice for racing series that allow 5.5" clutches, such as many asphalt Late Model series. MACH II 5.5" clutch-flywheel-assemblies provide a lower moment-of-inertia than 7.25" assemblies for quicker engine acceleration and deceleration.
 

Button Clutch-Flywheel-Assemblies Include: 5.5" MACH II clutch, discs, billet steel button flywheel, clutch-to-flywheel bolt kit and flywheel-to-crankshaft bolt kit.

MACH VIII 8.5" Clutch-Flywheel-Assemblies are designed for racing series that require a single plate clutch, but allow smaller (than OE) diameter clutches. MACH VIII clutch-flywheel-assemblies are ideal for use in most Stock Car classes that require a single-plate clutch. MACH VIII assemblies also provide a lower moment-of-inertia than 10.5" OE-type clutches and greater durability than 7.25" 1-plate clutches.
