Why Choose Mantic Clutches?

100% Billet construction will not flex under heavy usage like other stamped steel units. The red cover and components are machined from billet stock adding strength and durability. This Mantic Corvette clutch kit uses our unique sprung center with cushioned ceremetallic twin discs which aids in dampening engine harmonics for smooth clutch performance. The Mantic twin uses dual 9in diameter discs that greatly reduces the Moment of Inertia (MOI) for a seamless transition of power between gears. More power to the ground as well as quicker more precise shifts is the huge benefit over the stock clutch. The lightweight steel flywheel allows quicker revs compared to the heavier OE units.

Completely Rebuildable

The clutch is modular in construction for ease of service and is completely rebuildable. This is a popular alternative for worn out clutch discs and flywheels. Also, we can easily convert an existing twin disc clutch to a triple disc clutch.
