C-1- Custom stepped apply plate, (8) Carbonite C1 external
clutches, (8) Carbonite internal splines clutches with a custom
C1 top plate.
C-2- Custom stepped apply plate with (7) C-2 frictions and
(8) steels and (1) waved steel.
C-3- includes our (6) Carbonite double sided frictions with
no center slots and a waffle pattern in the material to help
retain oil to cool clutch when it’s not applied. (5)
Custom steels with no center slots. This design works great
in your daily driver, towing and even your extreme race conditions.
Suncoast has also redesigned the apply piston with improved
rubber compounds that are proven to hold more heat if the
circumstances arise. The custom piston allows us to use our
thicker spring apply plate that replaces the thin OEM one
deflects from the spring pressure and causes a uneven surface
for apply. This plate also redirects the oil to better lube
plates from the inside out which lubes the entire friction
rather than OEM style that lubes from the center out leaving
the inter half of the clutch burnt. Top apply plate is also
machined and included with kit.
C-4- includes (6) Carbonite single sided waffle pattern external
frictions and (6) Carbonite single sided waffle pattern internal
frictions. Suncoast also has redesigned the apply piston for
C4 with improved rubber compounds that is proven to hold up
to more heat if put in that situation than the OEM brands
will. The custom piston allows us to use our thicker spring
apply plate that replaces the thin OEM one that deflects from
the spring pressure and causes a uneven surface for apply.
This plate also redirects the oil to better lube plates from
the inside out which lubes the entire friction rather than
OEM style that lubes from the center out leaving the inter
half of the clutch burnt. Top apply plate is also machined
and included with kit.
