BD Diesel FleX-Plate

2007–2018 Dodge Ram 2500/3500 5.7L Hemi, 5.9L Diesel, 6.4L 392, 6.7L Diesel

Part #: 1041221

Overview

The BD Diesel FleX-Plate is engineered to withstand the extreme power and torque produced by modified Dodge Ram Cummins and Hemi engines. Stock flex plates often fail under the high stress of upgraded 5.9L and 6.7L diesel engines, leading to costly repairs and downtime. Designed as a direct bolt-in replacement, the BD FleX-Plate offers exceptional durability and reliability for both street and race applications.

Whether you are towing heavy loads, racing, or simply upgrading your truck’s drivetrain for enhanced performance, this flex plate provides the strength and peace of mind needed to handle torque levels well beyond factory limits. It is an ideal upgrade for Ram 2500 and 3500 models equipped with 5.7L Hemi, 5.9L Diesel, 6.4L 392, and 6.7L Diesel engines from 2007 through 2018.

Key Features

Built to deliver superior strength and longevity, the BD Diesel FleX-Plate includes the following key features:

• Handles over 2000 lb.-ft of torque, with capacity up to 3500 lb.-ft when paired with the BD Slip Eliminator shim kit
• Forged billet construction with twice the material thickness of the stock flex plate
• Precision-balanced for smooth operation and reduced vibration
• SFI approved for use in racing applications, ensuring high safety and performance standards
• Black Oxide coating resists corrosion and prevents hydrogen embrittlement that can cause cracking
• Compatible with any OEM or aftermarket torque converter
• Direct bolt-in replacement for easy installation without modifications
• Affordable upgrade option during converter or transmission swaps

Construction & Design

The BD Diesel FleX-Plate is crafted from forged billet steel, providing exceptional strength and durability compared to stamped or cast stock plates. The increased material thickness significantly reduces the risk of cracking or shattering under extreme torque loads common in modified diesel engines. Each flex plate undergoes precision balancing to ensure smooth drivetrain operation and minimize vibrations that can lead to premature wear.

The black oxide finish not only enhances corrosion resistance but also protects against hydrogen embrittlement, a common cause of flex plate failure in high-stress environments. This advanced coating extends the service life of the flex plate, making it suitable for demanding applications such as towing, racing, and heavy-duty use.

Installation & Fitment

The BD Diesel FleX-Plate is designed as a direct bolt-in replacement for the stock flex plate, requiring no modifications to your existing torque converter or transmission setup. It fits a wide range of Dodge Ram 2500 and 3500 models from 2007 to 2018, including:

• 2007 Dodge Ram 2500/3500 5.9L Diesel
• 2007–2015 Ram 2500/3500 5.7L Hemi
• 2014–2015 Ram 2500/3500 6.4L 392
• 2008–2018 Ram 2500/3500 6.7L Diesel

Installation is straightforward and can be completed during a torque converter or transmission swap, making it a convenient upgrade for enhanced drivetrain reliability.
