FAQ

What problem do traction bars fix on Duramax trucks?

Traction bars prevent axle wrap, which occurs when the rear axle rotates under heavy torque. This rotation causes wheel hop and loss of traction. Traction bars stabilize the axle and improve power delivery to the ground.

Do I need traction bars on a stock Duramax?

Stock trucks can benefit from traction bars when towing or launching under heavy load. They become especially important on trucks with performance tuning, upgraded turbos, or increased horsepower.

Will traction bars affect ride quality?

Properly designed traction bars like the WCF100851 are engineered to maintain normal suspension movement while controlling axle wrap. Most drivers experience minimal change in ride quality.

Are these traction bars adjustable?

Yes. The rod ends allow adjustment so the bars can be properly preloaded and aligned for optimal suspension geometry and performance.

Is this kit difficult to install?

The kit is designed as a bolt-on system using supplied brackets and hardware. Installation typically takes a few hours with standard tools.
