Strength You Can Count On When Power Matters Most

If you’re pushing your Duramax harder than stock, you know the flex plate is one of the first places weak links start to show. The SoCal Diesel BFP Billet Flex Plate gives you the strength and reliability needed to handle serious torque without hesitation. Whether you’re launching at the track or towing heavy uphill, this billet plate holds strong where the factory one just can’t keep up. It’s lighter than stock too, which means faster engine response and smoother power delivery under load. Designed specifically for 2001–2010 GM Silverado and Sierra 2500HD/3500HD models with the 6.6L Duramax, this flex plate is also a great upgrade for performance street builds. And because it’s already properly counterweighted, it bolts onto assembled engines without needing rebalancing. When you want confidence every time you hit the throttle, this is the kind of upgrade that delivers it.

Built For Torque Tested To Perform Under Pressure

The SoCal Diesel BFP Billet Flex Plate is engineered for precision fitment and high-torque durability across multiple generations of the 6.6L Duramax. It meets the demanding SFI 29.3 specification, which qualifies it for competitive motorsport use while also delivering real-world reliability on the street or worksite. This flex plate is CNC machined from high-strength billet material to ensure consistency, balance, and long-term durability even under intense drivetrain stress. SoCal Diesel offers separate part numbers to precisely match LB7, LLY, LBZ, and LMM engines, as well as their own stroker engine platforms. Each unit is carefully counterweighted so you can install it on an already assembled engine without requiring rebalancing, which simplifies installation and saves time. The lighter weight reduces rotating mass, allowing for quicker throttle response and smoother acceleration. Designed with both racers and heavy-duty diesel owners in mind, this flex plate is a serious upgrade for anyone looking to improve drivetrain reliability without compromising performance.
