You’ve invested your time, hard earned money, and passion (maybe even tears, it's okay we don’t judge) into upgrading your Cummins to make serious horsepower and torque. As those numbers climb, the stress on your drivetrain also increases, often revealing a critical weak point… the factory flexplate.

At D&J Precision Machine, we know that the reliability of your build is only as strong as its weakest component. That's why we feature purpose built flexplates designed to handle the massive output of modified 5.9L and 6.7L Cummins engines. Don't let a snapped or cracked stock plate get  you down. 

Here is a breakdown of the upgraded components we offer and how they ensure your power gets reliably delivered to the road (or the track).

1. Eliminate Slip: The HI5 12-Bolt Flexplate for 5.9L Cummins (47RH/47RE/48RE)

For those running the legendary 5.9L Cummins with a 47RH, 47RE, or 48RE transmission, you understand the demands of high torque applications. The factory flexplate setup often leaves room for failure where the torque converter bolts meet the plate, notorious for slippage.

The Benefit of a 12-Bolt Upgrade:

• Twice the Clamping Load: By moving from the standard 6-bolt design to a superior 12-bolt configuration, you gain double the clamping force. This effectively eliminates slippage between the torque converter and the flexplate, ensuring immediate, consistent power delivery.

• Maximized Torque Capacity: The HI5 Flexplate is engineered for performance, often including features like BD's Diamond Bite Shims to further maximize the holding capacity of the torque converter.

• Built to Last: This upgrade is a direct solution to a common failure,, giving you confidence when you put your pedal to the floor. 

2. Unbreakable Strength: The Flexplate for 6.7L Cummins (68RFE)

If you're driving a 6.7L Cummins equipped with the 68RFE transmission, you're likely leveraging the incredible torque potential of this modern diesel platform. However, the immense power and torque generated by modified engines can quickly stress a stock flexplate to its breaking point, often resulting in cracking or shattering.

Engineered to Endure Extreme Power:

• The Ultimate Insurance: Our upgraded flexplates are proven to handle power levels that would instantly destroy stock units. These components are specifically designed to reinforce your drivetrain against the violence of extreme torque.

• Built for the Big Numbers: They are proven to handle over 2000 lb-ft of torque right out of the box, with options available to push that limit even higher, up to 3500 lb-ft with additional BD Diesel components.

• Peace of Mind: When you're running a build that demands maximum performance, you need a component that is as tough as your engine. This upgrade ensures that the foundation connecting your engine to your transmission is solid.

The Bottom Line

When you’re pushing big power, your transmission components need to be ready for the stress. A performance flexplate is not just a replacement part, it’s a necessary upgrade that solidifies the connection between your powerful Cummins engine and the rest of your drivetrain.
