Built To Keep Your Power Where It Belongs

If you are pushing more power through your 6.7L Powerstroke, controlling axle wrap is not optional. The Wehrli 100399 68 inch Traction Bar Kit is designed to keep your rear axle planted when torque hits hard, whether you are towing heavy or laying into the throttle. Right away, the bars add a more connected and confident feel, especially under load or aggressive acceleration. Additionally, the combination of a RockJock Johnny Joint at the frame and polyurethane bushings at the axle helps maintain smooth drivability without the clunks and vibrations common with solid heims. Everything about this kit feels purpose-built, from the thick wall bars to the precise mounting hardware. What is more, the durable powder coat with epoxy primer ensures it holds up to road salt, mud, and daily abuse. Backed by a lifetime warranty against bending or breaking, this is the kind of upgrade you install once and trust for the long haul.

Designed Around Real World Fitment And Durability

This 68 inch traction bar kit is engineered specifically for 2017-2024 Ford F-250 and F-350 SRW trucks running Sterling 10.5 or Dana M275 rear axles with 4 inch axle tubes. The longer bar length is optimized for Regular Cab Long Bed, Super Cab Long Bed, Super Cab Short Bed, and Crew Cab Long Bed configurations, ensuring proper geometry and effective axle control. On the axle side, the mounts bolt directly to the factory u-bolts, keeping installation straightforward while maintaining strength. At the frame, weld-on mounts provide a solid attachment point that handles repeated load cycles without flex. Furthermore, the rebuildable and greaseable Johnny Joint allows for adjustment if ride height changes over time. Every kit includes Grade 8 hardware and is built in house at WCFab, ensuring consistent quality and precise fitment from start to finish.
