Fabtech heavy-duty rear traction bars are engineered to reduce rear leaf spring axle wrap on lifted 2017–2021 Ford F250/F350 4WD trucks, addressing torque loads from powerful engines and oversized tires. The shackle-style end allows movement with the leaf spring arch to avoid binding while providing positive resistance to axle wrap. Built for full wheel travel, these bars aim to preserve a smooth highway ride and strengthen traction.
