​Traction bars are a necessary upgrade when increasing the horsepower to prevent the axle from twisting which can lead to broken u-joints, driveshafts, and even twisted axle housings. Wehrli Custom Fabrication's 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.
