Strength Where It Matters Most

When you're putting serious work through your Duramax-powered Silverado or Sierra, you need transmission components that can handle the pressure. The SunCoast A1-C2S Sleeved C2 Clutch Hub is built with that exact goal in mind. This isn't just a reinforced version of a stock part—it’s a thoughtfully engineered upgrade designed to take on the high torque loads that come with towing, hauling, or running power-enhancing tunes. By integrating a precision-fit sleeve into the clutch hub, SunCoast has added a layer of strength that helps prevent distortion under stress. That extra durability means less wear over time, better clutch engagement, and fewer worries when you're relying on your truck to do the hard jobs.

Built for the Long Haul

This clutch hub is tailored for 2001 through 2010 GM 2500HD and 3500HD trucks with the 6.6L Duramax and Allison 1000 transmission. It’s a direct replacement that fits cleanly without modification, so you're not stuck with a complicated install. The sleeved design provides extra support in an area that sees a lot of stress, especially under load or in tuned applications. SunCoast has long been respected for pushing innovation in the transmission world, and this part shows exactly why. Every component is machined in-house with attention to the details that matter, giving you the confidence to push your truck harder, whether you're pulling a trailer across state lines or crawling through job sites day after day.
