KYB Strut Boots Front

Part #: SB123

Overview

The KYB Strut Boot Kit is engineered to protect the front struts of your Scion FR-S, Subaru BRZ, or Toyota 86 from harmful contaminants such as dirt, dust, sand, and road salt. These elements can cause abrasive wear on critical strut components including the polished shaft, upper seal, and bushing, leading to premature failure. By fully encasing the strut shaft in a durable plastic bellows, the KYB Strut Boot Kit effectively prevents debris from entering and damaging the strut assembly.

Designed for enthusiasts and daily drivers alike, this kit helps extend the life of your vehicle’s suspension system, maintaining optimal performance and ride quality. Additionally, the included poly foam travel-limiting bumper cushions the strut against bottoming out, protecting both the strut and surrounding components from damage caused by extreme suspension travel.

Construction & Design
