Customers appreciate the excellent quality and adjustability of our ball joint which also offers the ability to be rebuilt. They note it successfully corrected the lower control arm angle when lowering the chassis. Its compatibility with polyurethane dust covers was mentioned positively. However, customers suggest that inclusion of a protective boot would enhance the product, as they faced difficulty in finding a correct fit. Despite this minor concern, the superior quality and functionality of our product encourage customers to recommend it.

Great product, corrected the lower control arm angle when lowering the chassis between 4 and 5 inches. Only problem is that it doesn't come with a protective boot and finding something to work was difficult!
