This is a set (left and right housings) of missing bush that is not sold by Powerflex. If you have a kit by them you are missing this polyurethane bush in your rear suspension.
Polyurethane bushings work ideally in performance suspensions. Rubber suspension bushings are a proven compromise in performance vehicles. When additional horsepower is added, plus-size tires then OEM or rubber bushings tend to stress beyond design limits. Polyurethane bushings are strong enough to control movement and maintain wheel alignment.
