Product Information
A pair of spherical bushings that replace the rubber bushing where the rear traction arm bolts to the knuckle. Each one holds a Teflon-lined FK spherical bearing in a CNC-machined 6061-T6 aluminum housing, so the arm deflects less under heavy load and moves through its travel with less bind. SPL Parts uses the largest bearing that fits this spot for longer life and less noise and vibration.
