KYB SB140 Suspension Strut Bumper - Front

KYB SB140 Strut Boot for Jeep Front Suspension

The KYB SB140 strut boot is built to shield the strut shaft from dirt, dust, sand, salt, and other road debris that can wear down seals and bushings. For front suspension service on select Jeep Commander and Jeep Grand Cherokee models, it adds a durable protective layer where exposure is highest.

KYB Strut Boots are part of the KYB Strut Boots product line, focused on protecting exposed strut components from contamination and impact-related wear. The SB140 follows OE-style design and fit expectations for Jeep front suspension applications.

Key Features

• Superior-quality boot helps protect the strut shaft from leak-causing dirt and debris
• Poly foam bumper helps prevent the strut from bottoming out
• Built with design and quality that matches or exceeds OE
• Helps protect the upper seal and bushing from abrasive contamination
• Designed and built specifically for Jeeps

Detailed Description

The KYB SB140 is a suspension strut bumper and boot assembly designed for front applications on 2006-2010 Jeep Commander and 2005-2010 Jeep Grand Cherokee models. By covering the strut shaft with a durable plastic bellows, it helps keep abrasive road contaminants away from critical wear surfaces. The integrated poly foam bumper adds travel control to reduce harsh bottoming-out events and limit damage from extreme suspension movement. If you are servicing a Jeep Commander front strut or replacing worn front strut protection on a Jeep Grand Cherokee, the KYB SB140 provides a direct-fit service part for those applications.

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

What It Helps Address

• Strut shaft wear caused by dirt, dust, sand, and salt
• Seal and bushing damage from abrasive contamination
• Harsh suspension contact from bottoming out
• Damage from excessive suspension travel
• Premature deterioration of front strut protection components

Installation Notes and Tips

Install the SB140 during front strut service so the boot and bumper can be positioned correctly on the strut assembly. Inspect the strut shaft, upper seal area, and bushing surfaces before installation, and replace worn suspension components as needed. Confirm front fitment for 2006-2010 Jeep Commander and 2005-2010 Jeep Grand Cherokee before ordering.

Quality Assurance

KYB designs this strut boot kit to meet OE-style fit and quality expectations for Jeep front suspension service. The SB140 is engineered to provide durable protection for exposed strut components in demanding road conditions.
