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.
- – SunCoast proprietary C1, C2, C3, and C4 Alto carbonite frictions/Rabestos SCZ frictions that 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 higher heat. This custom piston allows us to use a thicker spring apply plate which replaces the thin OEM one that will cone and 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.
- – C5 clutches are not included but can be added to your kit upon request.
SunCoast Allison series rebuild kits cover all years from 2001-2015 (kit part number depen-dent upon year).

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.
