Built in house at WCFab carrying a LIFETIME WARRANTY against bending or breaking (to 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 on to 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 Polyurethane Bushing for decreased noise and vibration which is 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 color choice and comes standard with a Epoxy Primer base coat before the final color which increases corrosion resistance by more than ten times compared to just your standard powder single coat application. - - FITMENT NOTES: - 2011-2016 Ford F-250 & F-350 Super Cab / Crew Cab Short Bed use WCF100399 - 2017 or newer F-350 or F-450 Dually (DRW) trucks equipped with Dana M300 rear axle (4.5" diameter axle tubes) please see WCF100501 & separate bar options WCF100837 or WCF100839. - If you have a Lift Kit and your REAR lift block is taller than 5" or your total lift height is 6" or more, use WCF100399.
