The WEHRLI CUSTOM FAB WCF100852 2001-2010 DURAMAX 68" TRACTION BAR KIT FOR ECLB & CCLB is engineered to eliminate wheel hop, control axle wrap, and maximize traction for long-bed Duramax trucks. Built from heavy-duty materials and designed for both street and competition use, this traction bar system provides the strength and geometry needed to keep power planted to the ground.

High-horsepower Duramax trucks often suffer from axle wrap when launching or towing heavy loads. This can lead to wheel hop, poor traction, and premature drivetrain wear. Wehrli Custom Fab solves this problem with a precision-engineered traction bar kit that stabilizes the rear axle while maintaining suspension travel and ride quality.

Featuring 68-inch ladder bars designed specifically for Extended Cab Long Bed and Crew Cab Long Bed trucks, this kit provides the ideal mounting geometry for long wheelbase Duramax applications. Heavy-duty brackets, high-strength hardware, and adjustable joints allow precise setup while delivering race-proven durability.

Key Benefits:

• Eliminates wheel hop and axle wrap
• Improves traction during acceleration and towing
• Designed specifically for long bed Duramax trucks
• Heavy-duty fabricated steel ladder bars
• Adjustable rod ends allow proper suspension preload
• Maintains suspension articulation for street driving
• Built for high horsepower diesel performance builds
• Engineered and manufactured in the USA by Wehrli Custom Fab

This system is commonly used on performance street trucks, towing rigs, sled-pull trucks, and drag builds where maintaining consistent traction is critical. The durable design and proven geometry help protect driveline components while keeping the rear axle stable under heavy torque loads.

FAQ

What problem do traction bars solve?

Traction bars prevent axle wrap which causes wheel hop during acceleration. By stabilizing the rear axle housing, the bars help maintain tire contact with the ground and improve traction.

Will these traction bars affect ride quality?

No. When properly adjusted, the traction bars allow normal suspension movement while controlling excessive axle rotation under load.

Do these traction bars work with lifted trucks?

This kit is designed for trucks near factory ride height. Some lifted applications may require additional bracket adjustments depending on suspension setup.

Are these traction bars good for towing?

Yes. Many Duramax owners install traction bars to improve stability when towing heavy loads, especially on trucks producing higher torque levels.

Are these made in the USA?

Yes. Wehrli Custom Fab products are designed and manufactured in the United States using high-quality materials and fabrication processes.
