Clutches/Steels/Pressure Plates/C3/4 Pistons. All kits have been designed and tested by SunCoast with parts that have been designed and/or manufactured by us. All items included in this kit are recommend and used by SunCoast. No Hydraulic upgrades, gaskets or filters are included. *Core Charges for the C1 Pressure Plate, C3 Pressure Plate and C4 Pressure Plate apply.

Parts included are:

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 (7) steels.

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.

*C5 clutches are NOT included do to the fact they are normally good to re-use unless the unit has been contaminated by water or other foreign elements. C5 clutches are optional and can be added to our kit upon request.
