Ditch the Dual Mass and Step Up the Strength

If you’ve been dealing with the factory dual mass flywheel in your Duramax and you're ready for something stronger and more reliable, South Bend's 10701066-1 Single Disc Flywheel is the upgrade your truck deserves. Built specifically for 2001 to 2009 Silverado and Sierra 2500HD and 3500HD models with the 6.6L Duramax, this flywheel eliminates the weak points that come with a stock setup. Instead of the layered, failure-prone design of a dual mass unit, this one-piece solid flywheel offers straightforward durability that can take a beating without letting you down. Whether you're towing heavy loads, hauling tools to the job site, or pushing the truck harder than stock ever intended, this flywheel keeps everything spinning smooth and steady.

Engineered for Precision and Long-Term Reliability

What sets this flywheel apart is the attention to detail South Bend puts into every unit. It's crafted from low carbon, hot rolled steel—chosen specifically for its ability to resist warping, even under serious heat and pressure. The CNC machining process ensures exact tolerances and perfect balance, giving you better-than-stock performance right out of the box. Extensive field testing helps dial in the optimal weight for your truck, so you get smoother shifts and consistent performance without the chatter or vibration that can plague cheaper replacements. When you're putting your truck to work day in and day out, you want a flywheel that’s built to handle it. This one is.
