KYB SB133 Suspension Strut Bellows - Front

KYB Strut Boot for Explorer and Mountaineer

KYB SB133 is a front suspension strut bellows built for 2002-2005 Ford Explorer and 2002-2005 Mercury Mountaineer applications. It helps shield the strut shaft and internal sealing surfaces from road grit while adding travel protection at full compression.

Key Features

• Superior-quality boot helps protect the strut shaft from dirt and debris that can contribute to seal wear
• Poly foam bumper helps prevent the strut from bottoming out
• Built to match or exceed OE design and quality expectations
• Helps protect the upper seal and bushing from contamination
• Designed specifically for Ford Explorer and Mercury Mountaineer front suspension applications

Product Details

KYB Strut Boots are made to cover the strut shaft with a durable plastic bellows, reducing exposure to dust, sand, salt, and other road debris. By keeping abrasive contaminants away from the polished shaft and upper seal area, SB133 supports longer service life for the strut assembly. The included poly foam travel-limiting bumper adds compression protection during suspension movement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For buyers searching for a front strut boot for a 2002-2005 Ford Explorer or a 2002-2005 Mercury Mountaineer, KYB SB133 is the direct OE-style service part to review.

What It Helps Address

• Strut shaft wear caused by dirt, dust, sand, and salt
• Contamination around the upper seal and bushing
• Impact damage from suspension bottoming out
• Premature strut deterioration from road debris exposure
• Front suspension service needs on Explorer and Mountaineer models

Installation Notes and Tips

KYB SB133 is a focused fitment part for 2002-2005 Ford Explorer and 2002-2005 Mercury Mountaineer front applications.
