KYB SB129 Suspension Strut Bellows - Front

KYB SB129 Strut Boot Kit Protection

The KYB SB129 strut boot kit helps protect the front strut shaft from road grit, salt, dust, and sand that can wear on seals and bushings. It also includes a poly foam bumper to limit travel and help prevent bottoming out on rough roads.

Compatible with a wide range of front suspension applications, including Ford Mustang, Chevrolet Cruze, Chevrolet Malibu, and Nissan Pathfinder fitments, this KYB Boot Kit is built to match or exceed OE design expectations for service replacement.

Key Features

• Superior-quality boot helps shield the strut shaft from dirt and debris that can lead to leaks
• Poly foam bumper helps prevent the strut from bottoming out
• Built to match or exceed OE design and quality
• Helps protect the upper seal and bushing from contamination
• Fits front suspension applications across multiple makes and models

Detailed Description

KYB Boot Kits are made to cover the full strut shaft with a durable plastic bellows, reducing exposure to abrasive contaminants that can shorten strut life. By keeping debris away from the polished shaft and sealing surfaces, the KYB SB129 supports cleaner operation in front suspension service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Part number SB129 is a direct-fit style suspension strut bellows for many front applications, including 2015-2021 Ford Mustang, 2011-2015 Chevrolet Cruze, and 1996-2004 Nissan Pathfinder front fitments. It is also listed for select BMW Z4, Mercedes-Benz E-Class, INFINITI M35/M45, and GM truck and SUV applications.

What It Helps Address

• Dust and road debris reaching the strut shaft
• Seal wear caused by contamination
• Bushing wear from abrasive particles
• Strut bottoming out over bumps and dips
• Premature suspension service from exposed components

Installation Notes and Tips

Install the boot on the front strut assembly during strut service or replacement. Confirm the vehicle is listed by year, make, model, position, and suspension notes before ordering. For example, this part fits 2015-2021 Ford Mustang, front, w/o Electronic Suspension and w/o Performance Package; 2008-2014 Cadillac Escalade, front, exc. Electronic Adjustable Suspension; and 2003-2009 Mercedes-Benz E320, front, w/o Air Suspension, w/ Sport Suspension.

Always verify suspension options such as electronic suspension, air suspension, premium ride packages, sport suspension, and police package exclusions where noted in the fitment data.

Quality Assurance

KYB is a suspension brand known for OE-style replacement parts, and the SB129 is built with design and quality that matches or exceeds OE expectations for front strut protection.
