Product Details

Unity Automotive has more than 40 years of aftermarket suspension manufacturing experience, and this assembly reflects that focus on OE-style fit and function. The Unity product line is built around complete suspension solutions that simplify replacement on vehicles such as the BMW 525i, BMW 530i, BMW 528i, and BMW 535i. Part number 15552 is engineered as a complete rear right strut assembly so the spring, mount, and related components are already combined for service.

Common Problems This Part Can Address
