KYB SB103 Suspension Strut Bellows - Front, Front Left, Front Right or Rear

KYB SB103 Strut Boot Kit

The KYB SB103 strut boot kit helps protect exposed strut components from road grit and moisture. It is built for front and rear applications across a wide range of vehicles, including Subaru Legacy, Subaru Outback, Ford Taurus, and Toyota Corolla fitments.

Key Features

• Superior-quality boot helps protect the strut shaft from leak-causing dirt and debris
• Poly foam bumper prevents the strut from bottoming out
• Built with design and quality that matches or exceeds OE
• Protects the upper seal and bushing
• Durable plastic bellows covers the strut shaft to block contaminants

Product Details

KYB Boot Kits are made to shield the polished strut shaft, upper seal, and bushing from abrasive contaminants such as dust, sand, salt, and other road debris. By covering the shaft with a durable bellows, the KYB SB103 helps reduce wear that can lead to premature strut damage. The included poly foam travel-limiting bumper adds impact protection by helping prevent bottoming out during suspension compression. This part cross-references Monroe Shocks & Struts 63620 for the same application.

Compatible With front and rear strut applications on many vehicles, including 2011-2017 Buick Regal, front; 2010-2016 Buick LaCrosse, front; 2008-2016 Subaru Legacy, front; 2000-2009 Subaru Outback, rear; and 1986-2007 Ford Taurus, front. Additional fitments include Subaru Impreza, Dodge Charger, INFINITI QX50, and Toyota Corolla applications listed in the vehicle table.

What It Helps Address

• Strut shaft wear caused by dirt, dust, sand, and salt
• Damage to the upper seal from road contamination
• Bushing wear from abrasive debris exposure
• Bottoming-out impact during suspension travel
• Premature strut deterioration on daily-driven vehicles

Installation Notes

Verify year, make, model, and position before ordering. Some applications include exclusions such as electronic suspension, adjustable suspension, air suspension, or specific wheel and package combinations. On certain Toyota and Honda applications, the original upper spring insulator portion may need to be retained and modified during replacement. Confirm the vehicle’s suspension configuration before installation.
