KYB Suspension Strut Bellows P/N:SB146

Block out the grit that chews up your shaft seal with the KYB strut bellows SB146, a rear strut boot kit that wraps the strut shaft in a durable plastic bellows. It installs as a direct-fit replacement for the rear position on the 2018-2021 Mazda 6, 2016-2020 Mazda CX-3, and 2013-2025 Mazda CX-5 — see the Buyer's Guide tab for engine-level fitment.

Dirt, dust, sand, salt and other road debris cause abrasive wear to the polished shaft, upper seal and bushing. This kit covers the entire strut shaft to help keep those contaminants out, which can help extend the life of the strut.

• Durable plastic bellows: covers the entire strut shaft to help block leak-causing dirt and debris.
• Poly foam travel-limiting bumper: included in the kit; helps keep the strut from bottoming out and helps protect other components from extreme-movement damage.
• Protects the upper seal and bushing: shields the wear surfaces the strut relies on.
• Built to a design and quality that matches or exceeds OE.

If a torn, missing or deteriorated boot is exposing your strut shaft, this replaces it and re-covers the shaft.
