KYB SB137 Suspension Strut Bellows - Front

KYB Strut Boot Kit for Nissan and Infiniti

The KYB SB137 strut boot kit helps protect the strut shaft from road grit that can wear seals and bushings over time. It also adds a travel-limiting bumper to help reduce bottoming-out impact on the suspension.

Compatible with select Nissan Armada, Nissan TITAN, Infiniti QX56, and Nissan Pathfinder Armada front applications, this KYB Boot Kit is built for direct-fit service on the front suspension.

Key Features

• Protects the strut shaft from dirt, dust, sand, salt, and other road debris
• Helps shield the upper seal and bushing from abrasive wear
• Poly foam bumper helps prevent the strut from bottoming out
• Built to match or exceed OE design and quality
• Designed specifically for Nissan and Infiniti front suspension applications

Product Details

KYB Boot Kits are made to cover the exposed strut shaft with a durable plastic bellows, reducing contamination that can lead to premature seal damage and fluid loss. The included foam bumper adds suspension travel control, helping protect the strut and nearby components during extreme compression. For drivers searching for a KYB SB137 replacement for a Nissan Armada front strut boot kit or an Infiniti QX56 front suspension strut bellows, this part provides a focused OE-style service solution.

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

What It Helps Address

• Strut shaft wear caused by road debris
• Seal damage from dirt and contamination
• Bushing wear from abrasive particles
• Bottoming-out impact during suspension compression
• Damage to nearby suspension components from extreme movement

Installation Notes

Install on the front strut assembly only for the listed applications. Inspect the strut shaft, seal area, and surrounding suspension parts before installation, and replace worn components as needed. Verify vehicle fitment by year, make, model, and front position before ordering.

Quality Assurance

KYB builds this boot kit with design and quality that matches or exceeds OE expectations. The KYB Boot Kits line focuses on protecting suspension components from contamination and travel-related damage in service applications.
