The WEHRLI CUSTOM FAB WCF100876 2020-2024 DURAMAX 68" TRACTION BAR KIT is designed to control axle wrap and maximize traction on high-power L5P Duramax trucks. When torque increases from tuning, towing, or performance upgrades, the factory leaf spring suspension can allow axle rotation under load. This causes wheel hop, inconsistent traction, and unnecessary stress on drivetrain components.

The Wehrli Custom Fab traction bar system eliminates those issues by stabilizing the rear axle while still allowing normal suspension articulation. Using heavy-duty fabricated steel bars, precision heims, and durable frame mounts, the WCF100876 system provides consistent traction, smoother launches, and improved driveline stability whether your truck is daily driven, towing heavy loads, or making serious horsepower.

Each kit is manufactured in the USA with high-quality components and engineered for easy installation on long bed GM HD trucks. The long 68-inch bars provide proper geometry for optimal suspension movement while controlling axle wrap during acceleration.

FAQ

What problem do traction bars solve on Duramax trucks?

Traction bars prevent the rear axle from rotating under heavy torque loads. This eliminates wheel hop, improves traction, and reduces stress on driveshafts, leaf springs, and U-joints.

Will these traction bars affect ride quality?

No. The Wehrli system is designed to allow normal suspension movement while controlling axle wrap. Daily driving comfort is maintained while traction and stability improve.

Are these compatible with lifted trucks?

Most lifted trucks can run this system depending on suspension configuration. Spacer or bracket adjustments may be required depending on lift height.

What bed length are these traction bars designed for?

The WCF100876 kit is designed specifically for Duramax long bed trucks (DCLB and CCLB) using 68 inch traction bars for proper suspension geometry.

Are these traction bars adjustable?

Yes. The heim joint design allows adjustment to properly preload the bars and fine tune axle control for different power levels and driving conditions.
