The SunCoast Category kits utilize the latest proven friction materials and steel technology from industry leading companies such as Alto and Raybestos. SunCoast works directly with these companies to design and manufacture proprietary SunCoast exclusive product lines, giving the end user uncompromised quality throughout the entire transmission.
SunCoast has designed these kits in house to exact specifications for many in tents, including but not limited to towing, sled pulling, racing or simply having a vehicle to get from point A to point B.
Designed for light commercial vehicles in both on highway and public transport applications, Allison Transmission's 1000 and 2000 Series are rated up to 400 horsepower from the factory. Allison 5-speed transmission started in 2001 with GM equipped Duramax engines.
Kit Exclusives:
- SunCoast-Proprietary C1, C2, C3, C4 ALTO® Carbonite Frictions & RAYBESTOS® SCZ Frictions, which contain no center slots. These 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 more heat. This custom piston allows us to use a thicker spring apply plate, which replaces the thin OEM one and, in turn, causes an uneven apply surface.
- Custom apply plate that redirects fluid to better lubricate frictions from the inside out, which lubes the entire friction rather than the 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.
New Internal Wiring Harness
Every build here at SunCoast reliability is our number one priority. Each one of our (Category) Allison rebuild kits comes with a new internal wiring harness. As the transmission continues to age, the plastic connectors become brittle and will break during disassembly. This often leaves builders scrambling around looking for a replacement last minute. This is a new GM harness with all new connectors.
