Wehrli Traction Bar Kit

1994–2024 Dodge Ram 2500/3500 5.9L & 6.7L Diesel

Part #: WCF100854-RED

Overview

The Wehrli 60-inch Traction Bar Kit is a vital upgrade for Dodge Ram diesel trucks from 1994 through 2024 equipped with 5.9L and 6.7L engines. Designed to combat axle wrap and twisting caused by increased horsepower and torque, this kit protects critical drivetrain components such as u-joints, driveshafts, and axle housings from premature failure. Ideal for diesel truck owners who have enhanced their engine performance or who demand improved rear suspension stability, this traction bar kit ensures reliable power transfer and durability under heavy loads and aggressive driving conditions.

By reinforcing the rear axle assembly, the Wehrli traction bars maintain proper alignment and reduce drivetrain stress, enhancing both vehicle longevity and driving confidence.

Key Features

This traction bar kit combines robust engineering with practical design features to deliver superior performance and durability:

• Heavy-duty brackets that weld securely to the bottom of the axle tube and frame front for maximum strength
• RockJock rebuildable and grease-able Johnny Joint heim connection at the frame end for precise torsion adjustment and adaptability to rear ride height changes
• Polyurethane bushings at the axle connection to minimize noise and vibration, improving ride quality compared to solid heim joints
• Grade 8 hardware for secure, long-lasting attachment of bars to mounts
• Professional in-house powder coat finish with an epoxy primer base coat for enhanced corrosion resistance—over ten times greater than standard single-coat powder finishes
• Bright red powder coat color for a distinctive, durable appearance
• 60-inch bar length optimized for Dodge Ram 2500 and 3500 models

Construction & Design

Manufactured with high-quality steel components, the Wehrli traction bar kit is engineered to withstand the rigors of heavy-duty diesel truck use. The weld-on brackets provide a solid foundation by attaching directly to the axle tube and frame, ensuring minimal flex and maximum control. The use of a RockJock Johnny Joint heim connection at the frame allows for easy adjustment and rebuildability, extending the service life of the kit. Polyurethane bushings at the axle end reduce unwanted noise and vibration, a common issue with solid heim joints, delivering a smoother driving experience.

The entire assembly is finished with a durable powder coat process that includes an epoxy primer base coat, significantly enhancing corrosion resistance and ensuring the kit maintains its structural integrity and appearance over time, even in harsh environments.

Installation & Fitment

Installation requires welding the brackets to the axle tube and frame, making professional installation or welding experience recommended. The adjustable heim joint at the frame end allows for fine-tuning torsion on the axle and accommodates changes in rear suspension height, such as lifts or lowering. This kit is specifically designed to fit the following Dodge Ram models:

• 1994–2007 Dodge Ram 2500 5.9L Diesel
• 1994–2007 Dodge Ram 3500 5.9L Diesel
• 2008–2010 Dodge Ram 2500 6.7L Diesel
• 2008–2009 Dodge Ram 3500 6.7L Diesel
• 2011–2013 Ram 2500 6.7L Diesel
• 2011–2024 Ram 3500 6.7L Diesel

Proper fitment ensures optimal performance and protection for your truck’s drivetrain components.
