Stock trucks can benefit from traction bars with the animals these Duramax's are from the factory. But once you throw some mods at these trucks then it's almost necessary! Curb axle hop and twist with these Wehrli traction bars and let's be honest.....traction bars look sweet too!
Built in house at WCFab carrying a LIFETIME WARRANTY against bending or breaking (to the original purchaser). Traction bars are a necessary upgrade when increasing the horsepower on your diesel truck to prevent the axle from twisting which can lead to broken u-joints, driveshafts, and even twisted axle housings. Our traction bar brackets bolt onto the bottom of the axle tube via the axle u-bolts and weld to the frame on the front end. We use a high-quality RockJock rebuild-able and grease-able “Johnny Joint” heim connection at the frame to allow for adjustment of torsion on the axle or if you raise/lower the rear of your truck. At the axle connection, we use a heavy-duty Poly Urethane Bushing for decreased noise and vibration which is a common complaint if a solid heim is used on both ends. Grade 8 hardware connects the bars to the mounts on the frame and axle. We complete our traction bar kit with our professional in-house powder coat process in your colour choice and comes standard with an epoxy Primer base coat before the final colour which increases corrosion resistance by more than ten times compared to just your standard powder single coat application.
