Wehrli Traction Bar Kit

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

Part #: WCF100854-SGB

Overview

The Wehrli 60-inch Traction Bar Kit is an essential 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. Whether you’re upgrading your truck for towing, hauling, or performance driving, these traction bars provide enhanced stability and durability under demanding conditions.

By reinforcing the rear axle assembly, the Wehrli traction bars help maintain proper alignment and reduce drivetrain stress, ensuring your truck’s power is efficiently transferred to the ground without damaging costly components. This kit is ideal for diesel truck owners looking to maximize reliability and performance while preserving factory driveline integrity.

Key Features

Engineered for durability and adjustability, the Wehrli Traction Bar Kit includes:

• Heavy-duty brackets that weld securely to the axle tube and frame for a robust connection
• RockJock rebuildable and greaseable Johnny Joint heim connection at the frame end for torsion adjustment and rear ride height changes
• Polyurethane bushings at the axle connection to reduce noise and vibration commonly associated with solid heim joints
• Grade 8 hardware for superior strength and corrosion resistance
• Professional in-house powder coat finish with an epoxy primer base coat, offering over ten times the corrosion resistance compared to standard single-coat powder finishes
• 60-inch bar length optimized for Dodge Ram 2500 and 3500 models with 5.9L and 6.7L diesel engines
• Compatible with a wide range of model years from 1994 to 2024, covering multiple generations of Dodge Ram trucks

Construction & Design

The Wehrli traction bars are constructed from high-strength steel components designed to withstand the rigors of heavy-duty diesel truck use. The weld-on brackets provide a secure foundation by attaching directly to the axle tube and frame, ensuring minimal flex and maximum torsional control. The use of a RockJock Johnny Joint heim connection at the frame end allows for precise adjustment and long-term serviceability through rebuild and greasing.

At the axle end, polyurethane bushings replace solid heim joints to minimize vibration and noise, enhancing ride comfort without sacrificing strength. The entire assembly is finished with a durable semi-gloss black powder coat applied over an epoxy primer base, delivering exceptional corrosion protection and a professional appearance that lasts.

Installation & Fitment

Installation requires welding the included brackets to the axle tube and frame, making this kit best suited for professional installation or experienced DIYers with welding capabilities. The adjustable heim joint allows for fine-tuning to accommodate torsional changes or rear suspension height adjustments, such as lifts or lowering. This kit fits the following Dodge Ram models and engines:

• 1994–2007 Dodge Ram 2500 5.9L Diesel
