SunCoast Performance

The big diesel motor under the hood of your full-size truck is more than capable of making huge power with even the most basic tuning and parts, but you need to make sure that your truck's transmission can actually handle it. SunCoast offers up a full lineup of high-strength torque converters, billet transmission parts, and even complete transmissions that can handle all the power and torque that your big diesel truck can throw down. SunCoast offers Duramax transmission upgrades, Cummins transmission upgrades, and Powerstroke transmission upgrades that are all designed to handle big power and tough applications without letting you down.
