Kit Features:

• SunCoast proprietary C1, C2, C3, and C4 Alto carbonite frictions/Raybestos SCZ frictions that contain no center slots
• Frictions utilize a waffle pattern in the material to help retain oil helping the clutch cool when not applied.
• Redesigned apply pistons with improved rubber compounds proven to hold higher heat
• Allows use of thicker spring apply plate which replaces the thin OEM one that will cone & cause uneven apply surface resulting in premature clutch failure
• Custom SunCoast apply plate that redirects fluid to better lubricate frictions from the inside out which lubes the entire friction rather than OEM style that lubricates from the center out leaving the inner half of the clutch burnt
