Tuff Country 6-degree axle shim, 2-inch wide with 3/8-inch center pins, is intended for rear axle installations on trucks and SUVs with leaf springs. The tapered shim rotates the axle to alter pinion angle, which can reduce or eliminate driveline vibration after lift kit installation and improve rear-end alignment with the drivetrain.
