For drivers searching for a rear strut boot for 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, or 2006-2010 Mercury Mountaineer, KYB SB134 provides a direct-fit solution focused on shaft protection and suspension travel control.

Key Features

• Superior-quality boot helps protect the strut shaft from dirt and debris that can contribute to seal wear and leaks

Product Details

The KYB Boot Kits line focuses on keeping exposed strut components shielded from dust, sand, salt, and other road debris. On the SB134, a durable plastic bellows covers the strut shaft to reduce abrasive wear on polished surfaces and help preserve the upper seal and bushing. The included poly foam travel-limiting bumper adds impact protection during suspension compression. KYB SB134 is a practical choice for rear suspension service on the Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
