SunCoast Category 1 kits offer the same recipes as their in house builds that have been proven for years both at the track and on the road. This rebuild kit includes everything you will need to build your Allison the same way SunCoast builds them in house, including detailed instructions that will walk you through each step of the process. These kits utilize the latest proven friction materials and steel technology from industry leading companies such as Alto and Raybestos. This kit is best suited for daily driver/tow applications with little to no modifications done to the truck. Perfect for customers who already have their own torque converter.

Includes:

• Custom clutches & steel
  
• Custom billet plates
• Custom overhaul kit
• Valve body calibration kit
• Gasket kit
• Internal Filter

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
  
• Includes exclusive smart trim/clutch control valve
• Includes all items needed to modify the C2 clutch piston for increased clutch durability
