KYB SB148 Suspension Strut Bellows - Rear

KYB SB148 Rear Strut Boot Kit

The KYB SB148 rear strut boot kit helps protect the strut shaft and seal area from dirt, dust, sand, salt, and road debris. It also includes a travel-limiting foam bumper to help reduce damage from bottoming out.

Key Features

• Durable plastic bellows covers the strut shaft
• Helps shield the polished shaft, upper seal, and bushing from abrasive contamination
• Poly foam bumper helps limit travel during suspension compression
• Direct replacement for rear strut boot applications on select Hyundai and Kia models
• KYB Strut Boots line focus: protection for strut components exposed to road debris

Product Details

KYB SB148 is a suspension strut bellows designed for rear applications on the 2021-2024 Hyundai Tucson and 2021-2022 Kia Sportage, plus earlier rear strut boot applications on the 2016-2020 Hyundai Tucson and 2017-2020 Kia Sportage. By covering the exposed strut shaft, the boot helps reduce wear caused by contaminants that can reach the seal and bushing area. The included foam bumper adds compression protection during extreme suspension movement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. KYB SB148 is a practical replacement when servicing rear strut protection on Hyundai Tucson and Kia Sportage models.

What It Helps Address

• Strut shaft wear from dirt, dust, sand, and salt
• Seal damage caused by road debris intrusion
• Bushing wear from abrasive contamination
• Bottoming-out impact on the rear strut assembly
• Damage from excessive suspension travel

Installation Notes

Install on the rear strut assembly only for the listed Hyundai Tucson and Kia Sportage applications. Inspect the strut shaft, seal area, and surrounding suspension components before installation, and replace worn parts as needed during service. Verify vehicle year, make, model, and rear position against the fitment list before ordering.

Quality Assurance

KYB manufactures suspension components with a focus on OE-style fit and function for service replacement applications. The SB148 follows that approach by providing a protective boot and bumper assembly for listed rear strut applications.
