Part #: SB171

Overview

The KYB Hybrid Rear Strut Boot Jounce Bumper and Bellows are essential components designed to protect your vehicle's rear suspension system. Specifically engineered for Ford Fusion models from 2013 to 2020, as well as Police Responder and SSV variants from 2019 to 2020, these strut boots serve as a vital shield against environmental contaminants. Whether you're a daily driver or an enthusiast seeking to maintain optimal suspension performance, these boots help extend the lifespan of your struts by preventing dirt, dust, salt, and other debris from entering and damaging the sensitive components.

By installing these durable bellows, you ensure that your suspension remains responsive and reliable over time. They are particularly beneficial in harsh driving conditions, off-road adventures, or urban environments where road debris is prevalent. The inclusion of a poly foam travel-limiting bumper further enhances protection by preventing the strut from bottoming out, reducing wear and potential damage during aggressive driving or rough terrain.
