KYB Suspension Strut Bellows P/N:SB163
Shield your strut's polished shaft with the KYB strut bellows kit SB155, a direct-fit front replacement for the listed applications. It fits many vehicles, among them the 2018-2020 Chevrolet Traverse, 2017-2020 GMC Acadia and 2018-2020 Buick Enclave. This KYB Strut Boot Kit wraps the entire strut shaft to block dirt, dust, sand, salt and other road debris — the abrasive contaminants that wear the polished shaft, upper seal and bushing and can lead to leaks. See the Buyer's Guide tab for the full list and engine-level fitment.
If a torn or missing boot has left your strut shaft exposed to grit, this kit is designed to replace that protection during a strut service.
What is the KYB strut bellows SB155?
It's a KYB Strut Boot Kit with a durable plastic bellows that covers the full strut shaft, plus a poly foam jounce bumper. It helps keep dirt, dust, sand and salt off the shaft, upper seal and bushing.
Which vehicles does the SB155 fit?
It's a front application for many vehicles, including the 2018-2020 Chevrolet Traverse, 2017-2020 GMC Acadia and 2018-2020 Buick Enclave. See the Buyer's Guide tab for the full list.
What does the poly foam bumper do?
The travel-limiting poly foam bumper is designed to keep the strut from bottoming out and to protect other components from extreme-movement damage.
Why does a strut need a boot?
Dirt, sand, salt and road debris cause abrasive wear to the polished shaft, upper seal and bushing. The bellows covers the shaft to block those contaminants, which can help extend strut life.
Does this kit include the strut?
No. This is a boot kit consisting of the bellows and poly foam bumper only; it protects a strut but does not replace one.
