Want to reduce bushing deflection and change out your tired OEM rear knuckle bushings? We have the solution. We have made replacements, however, they are a spherical bushing rather then a polyurethane or rubber bushing to significanty reduce bush deflection and ensure a much smoother operation throughout the range of suspension travel. As with all of the bearings that we use throughout our suspension arms, these spherical inserts use common sized bearings which essentially makes them rebuildable at a very low cost should the need arise. Sold as a set of 8. Vehicle Compatibility: - Nissan Z33 350z - Infiniti G35 - Nissan Z34 370z - Infiniti G37
